June in Your Patch

Ok, it’s official, winter is upon us. And while it may seem easier to curl up on the couch with a cup of tea and a good book, it is the perfect time to get amongst it in the patch! There is a sense of hibernation for a lot of us but wherever you are in this nation it’s time to don the boots and get to it.

Warm Areas

Frost free or occasional light frosts (North from about Coffs Harbour and all the way across to the west to Geraldton)

  • Time to plant some winter crops – think about some leeks, rocket, beetroot, celery, lettuce (oak leaf), broccoli, cabbage, carrots, cauliflower, onions, kale, kohl rabi, spinach and silverbeet.

  • Pop in some coriander and chamomile… perfect for warming winter curries and cups of tea!

  • Stick in some spuds, home grown is easy, and incredibly rewarding. The potato page is here! Don’t forget about sweet potatoes, they are great fun to grow as well!

  • There are a load of fruity favourites ready to go in, including kiwifruits and figs! Remember that kiwi fruits need to cross pollinate, so ensure you pick up one of each sex so that they can cross pollinate.

  • Nuts such as pistachio or pecan can also be planted. Beautiful trees in their own right, these nuts are number one in the garden!

  • A seaweed tea, or any low environmental impact liquid fertiliser is perfect for giving plants a kick start as they establish. Apply to the soil early in the morning and in the concentrations mentioned on the packet. Don’t forget to give the fruit trees a bit of a feed as well (particularly paw paw).

  • Much needed at this time of year is colour.  marigolds, lupins, pansies, violas, phlox, verbena and lavender (non-invasive varieties of course!). Popping these in around your veggies will give some colour and interest to the patch, and act as beneficial insect attractors!

  • Consider a green manure crop to add some life and love to an overworked patch. At this time of year, try millet, oats, lupins or field peas. This will improve your soil incredibly, and, as a bit of forward planning, you’ll find it well worth the effort!

  • Water smarter at this time of year. Water first thing in the morning, and instead of quickie irrigation, a nice, deep drink a couple of times a week is far more beneficial! Always check soil moisture before watering at this time of year….don’t waste your precious drinking water if Mother Nature has already done all the hard work for you!

  • Top up mulch on your veggie patches, herb gardens and ornamental beds, especially important for weed suppression at this time of year. A hot tip is to mulch after watering, to a depth of about 7cm. Keep mulch clear of plant stems, especially young seedlings. Choose sustainable, low environmental impact mulch, one that will enrich your soil as it breaks down. Also look for one that has done the lest amount of travel to get to you.

  • Weeding is still needed at this time of year. Most plant growth has slowed down though so it will not have to happen as often. But it also means that it is also a time of year to try and remove as many competitors as possible before the weather starts warming up again.

Cool to Cold Areas

Low temperatures for extended periods of time (all of Tasmania, most of Victoria, the southern highlands of NSW, the ACT and a tiny southern bit of SA)

  • You should start seeing bare rooted fruit and deciduous trees starting to appear in your local nursery. This is the cheapest and easiest way to purchase. The stress is less for the tree as it is dormant.  Pick trees with a nice shape, and don’t forget to prune them back before you plant them out (best thing to do is ask the local nursery to do it for you). Remember to make sure you have the correct pollinators to ensure a good crop. Some stone fruit trees will not fruit until they have been in the ground for a few years. So be patient.

  • Give Brassica’s a place in your patch, pop in the following: broccoli, cabbage, cauliflower and Brussels sprouts. Plant some sage with these guys as a great, caterpillar and moth-repelling companion!

  • For plants that will settle in over winter, so that when spring comes along, they will go gang busters are: peas, beans, radish, Swedes, turnips and spinach. Oh, and some spring onions would go a treat this month as well.

  • Set aside a bit of space and pop in an artichoke! These are gorgeous additions to the patch, look amazing, and taste pretty good too!

  • Plant some rhubarb crowns. Set aside some space in the patch, and check out out the Rhubarb fact sheet for all the tips and tricks.

  • Add some colour and movement to the patch, and pop in some of these little pretties- dianthus, cornflower, pansy, viola, verbena and lupins. Having these around your veggies will give some interest to the patch, and act as beneficial insect attractors!

  • Top up mulch on your veggie patches, herb gardens and ornamental beds, especially important for weed suppression at this time of year. A hot tip is to mulch after watering the patch, to a depth of about 7cm. Keep mulch clear of plant stems, especially young seedlings. Choose low environmental impact mulch, one that will enrich your soil as it breaks down. Also look for one that has done the lest amount of travel to get to you.

  • Green manure crops, including oats, wheat, faba beans and field peas are good to go now. Improve that nutrient deficient veggie patch, and get ready for next seasons heavy feeding plants!

  • A seaweed tea, or any low environmental impact liquid fertiliser are perfect for the seedlings you’ve just popped in. Apply to the soil early in the morning, and in the concentrations mentioned on the packet.

  • Weeding is still needed at this time of year. Most plant growth has slowed down, so it will not have to happen as often. But it also means that it is also a time of year to try and remove as many competitors as possible before the weather starts warming up again.

  • Water smarter at this time of year. Water first thing in the morning, and instead of quickie irrigation, a nice, deep drink a couple of times a week is far more beneficial! Always check soil moisture before watering, don’t waste your precious drinking water if Mother Nature has already done all the hard work for you!

  • Cold days mean a bit of shed time… why not build yourself a nice blackboard for the shed, to keep track of what has been planted in your patch where and when? This makes crop rotation a load easier, and allows you to keep track of feeding times and dates, what worked, what didn’t and what’s happening in the veggie garden.

Temperate Zones

Occasional winter frosts (pretty much the rest of Australia, most of the inland, some areas of Victoria, most of SA and the southern area of WA)

  • Great time to plant in the temperate zones, so pop in some Brussels sprouts, cabbage, cauliflower and broccoli. Peas and beans can also go in, as well as radish, turnips, Swedes and spinach.

  • It’s time to get happy with herbs, so try some chamomile and lemon grass. You could give mint and lemon balm a go as well, but be careful to contain them as they can take over.

  • Why not try some lovely flowering stuff in your patch as well, like: cornflower, calendula, dianthus, pansies, viola, snapdragons, stock, ageratum and marigolds. These guys are great at attracting pollinators and beneficial insects to your patch, and I reckon they look tops as well.

  • You should start seeing bare rooted fruit and deciduous trees starting to appear in your local nursery. This is the cheapest and easiest way to purchase. The stress is less for the tree as it is dormant.  Pick trees with a nice shape, and don’t forget to prune them back before you plant them out (best thing to do is ask the local nursery to do it for you). Remember to make sure you have the correct pollinators to ensure a good crop. Some stone fruit trees will not fruit until they have been in the ground for a few years. So be patient.

  • Consider a green manure crop to add some nutrients back into your patch, especially before planting heavy feeders in spring. At this time of year try faba bean, field pea, oats and wheat. This will improve your soil incredibly, and, for a bit of forward planning, you’ll find it well worth the effort!

  • Top up mulch on your veggie patches, herb gardens and ornamental beds, especially important for weed suppression at this time of year. A hot tip is to mulch after watering the patch, to a depth of about 7cm. Keep mulch clear of plant stems, especially young seedlings. Choose low environmental impact mulch, one that will enrich your soil as it breaks down.

  • Plants feel the need for a feed at this time of year. A seaweed tea or low environmental impact liquid fertiliser is perfect, especially for the seedlings planted this month. Apply to the soil early in the morning, and in the concentrations mentioned on the packet.

  • Weeding is still needed at this time of year. Most plant growth has slowed down, so it will not have to happen as often. But it also means that it is also a time of year to try and remove as many competitors as possible before the weather starts warming up again.

  • Water smarter at this time of year. Water first thing in the morning, and instead of quickie irrigation, a nice, deep drink a couple of times a week is far more beneficial! Always check soil moisture before watering, don’t waste your precious drinking water if Mother Nature has already done all the hard work for you!

Of course, this is just a rough guide, and many of you will find your situation varies from the above listing, due to microclimates created in your garden, location in relation to your nearest major city, extremes of weather (Mother Nature does like to keep us on our toes) and garden type.

Gall (of Australian Native Trees)


Hi, my name is: Gall (of Australian Native Trees)
Describe yourself: I guess some people would describe me as an abnormal growth on plant parts, but I reckon I'm just a regular lump, hanging around on stems, leaves, buds, and, when the mood strikes….roots! I may look pretty boring (and a little ugly) on the outside, but I'm actually really interesting under the surface! Size wise, I can go from minute to big and hideous, and my colours can vary from red to yellow and even brown!

Hobbies: I am the result of plant cells' reaction to invasion by my friends e.g. wasps, beetles, moths, coccids, psyllids or bacteria. I don't move around at all (I just hang out growing bigger and bigger) and, once I've settled in, I stay for a long while!

Likes: Loads of Australian native plants, but I really love Eucalypts, Acacias, Lilypillies and Hakeas. I like making your prized native trees look really ugly... but I don't always kill them!

Dislikes: Well... not much, but the little pests who cause me are not huge fans of birds and other insect eaters. You see, I am often formed when little wasps, beetles and insects lay their eggs in plant parts, so a really diverse habitat with loads of bird activity will certainly upset me!

You'll Know You've Met Me When: Certain parts of your trees have lumps on them. In wattle trees and hakeas, I grow on the branches and look like a big seed pod. But on eucalypts I can appear a bit like a little pimple on the leaves. When I hang out on lilly pillies, I look like bubbles and pimples on their beautiful foliage!

Breaking up ain't hard to do... if:

  • Accept that tiny lumps and bumps are all part of nature….I mean, we can't all look like supermodels!
  • Encourage backyard biodiversity….having birds, lizard and insects in the garden will help keep the critters that cause galls under control.
  • When buying Lillypillies, look for varieties that are less susceptible to psyllid….there's heaps of them out there!
  • Cut off areas if they are really offensive to you….as I said, I probably won't kill your tree, so this is a last resort!

March In Your Patch

March, the month named after Mars, the Roman God of War, is an excellent month to wage war on your patch. Be it ripping out the weeds, mulching up a storm, or popping in a plethora of plants, March is the ultimate time to launch a full scale (but well planned) attack on you patch! So, all you weekend warriors … March into action!Read more

Early Blight of Tomatoes

Hi, my name is: Early Blight of Tomatoes

Describe yourself: I'm a saucy little fungal disease with a real thing for the leaves of tomato plants! People say I'm common, but I reckon I'm an angel, a brown spot with a gorgeous yellow halo.

Hobbies: I adore the older leaves of tomato plants, but don't mind a stem, or entering the fruit through growth cracks or the fruit stalk. I'm movin' on up baby... I start on your older leaves and work my way to the top of the plant, causing defoliation as I go. If I have to have a young plant, I would definitely go for the base of the stem... I'm partial to a bit of collar rot!

Likes: Oh, I love to get busy when the weather is over 15⁰C and there is lots of moisture around... it really gets my spores flying and my lesions growing! Love humidity, when you over fertilise your tomatoes (oh yeah baby, I love that), shade and water lying around on leaves. I love really crowded gardens where there is no air movement.

Dislikes: Sun, well mulched garden beds, when you clean up fallen leaves, hate well prepared soil with heaps of organic matter, home made spray remedies (like milk sprays and bi-carb mixes), store bought good sprays. I really don't like gardeners who monitor their plants all year round!

You'll know you've met me when: Your tomatoes lack serious vigour, older leaves are seriously ugly with spots, and some fruit shows damage (at the stalk end). Check young plants for collar rot.

Breaking up ain't hard to do... if you

  • Mix fat-free milk with water in a 1:1 ratio and apply it using a spray bottle. Spray the solution directly onto the clean leaves of your tomatoes. Milk-and-water solution coats the leaves and leads to the growth of an invisible fungus that frightens off black spot!
  • To four litres of water, add 3 level teaspoons of bicarbonate of soda and a couple of good splashes of fish emulsion. Give it a good mix and spray it on weekly. Don't apply when it's hot. The Fish emulsion is very useful because it helps to make it stick. It also contains beneficial bacteria that have antifungal properties. And that's not all - the oils in fish emulsion will help to suffocate pests like mites/aphids/scale. You must use it weekly for it to be most effective.
  • Seaweed sprayed onto the leaves changes the pH of the leaf surface making it less attractive to the fungal spores. It also strengthens the cell walls making it more difficult for the invading fungi.
  • Low Environmental Impact fungicides are available, but success is limited and control can be difficult.
  • Destroy all infected plants and dropped leaves by bagging and disposing in rubbish, or burning. Do not compost.
  • Rotate your crops!!! Don't plant the same crops, or susceptible crops in the same area each season.

Pumpkin

Pumpkins, the source of many a young girl's daydreams. Turns into a carriage, takes you to the ball, something about glass slippers and a happy ending! As a young girl, and even as a not so young girl, I was never one for the whole Cinderella thing, but I too had dreams of pumpkins! Well, more specifically, my Mum's pumpkin soup! The secret ingredient to this oft imitated, never duplicated soup, was home grown pumpkinney goodness (or ginger, I can't quite remember). So now you too can grow your own giant orange balls of tastiness!

Planting Schedule

Warm Areas: All Year Round!
Temperate Areas: After last frost in winter
Cool to Cold Areas: After last frost in winter

Position, Position, Position!

The biggest thing to remember about pumpkins is that they LOVE space, and I reckon that each vine needs about 1m². So, here's a hot tip: find a sunny spot out of the way a bit (like the forgotten side of the house or shed), pile up some compost, whack in two vines and walk away. Pumpkins like their privacy, and can suffer a bit if they are trod on, cut or damaged.

Talking Dirty

Growing pumpkins is so easy, even my evil stepsisters can manage it (that's a joke by the way!). Pumpkins love compost, I mean they really love compost. That's why you'll often find a pumpkin vine growing out of old compost piles. So, the more compost the better! Pumpkins vines will root where they come into contact with the ground, and this should be encouraged as it produces more pumpkins and stronger plants.

Feed Me!

If you have planted your pumpkins in a nice, rich, compost filled Yummy Yard, there is absolutely no need to feed!

What about the Water?

The other thing that pumpkins love, in addition to compost and space, is a moist, well-drained soil. Soil with a high compost content will retain moisture, as will a nice mulch layer. Now, before you go nuts on the end of the hose, use your moisture sensor! What do you mean you don't have one? Your pointer finger is the greatest moisture sensor in the world... and most of us have two of those. Stick your chosen finger in the soil, and remove. Is it damp, and is there dirt stuck to your finger? If yes, it doesn't need a drink. If no, read on! Water in the morning, to avoid water on the foliage as the temperature cools down, and never, ever, ever water pumpkin with greywater!

Are We There Yet?

Pumpkins, depending on the variety, take between 70 - 120 days to mature, which is a bloody, long time, but totally worth the wait! You can tell when a pumpkin is ripe when you give it a knock on the side, and it sounds hollow. The skin should feel hard and the tendril closest to the fruit should be dead. When removing the pumpkin from the vine, be sure to keep about 5cm of stalk on top.

If you don't plan on chowing down or carving up your pumpkin straight away, I recommend "curing" it by sitting it in the sun for a while (about a week), and then storing it in a cool, dark (but not damp) place. Well-cured pumpkins can last for up to ten months.

Pests and the Rest

A common problem with pumpkins isn't so much a pest issue, but a pollination problem. For years I grew pumpkins with magic vines, but no real fruit. The problem was that small fruits would form, go yellow, and fall off. I overcame this with hand-pollination! The trick is to pick the boy flowers (the ones without the tell-tale bump at the base), take the petals off, and lightly rub the pollen on the sticky bits of the female flowers.

As for real pests - well, there's not much, but keep an eye on fuzzy mildews (like Powdery Mildew or Downy Mildew). Have a read of those two factsheets should these little fungal nasties appear!

Hot Tip

Don't grow pumpkins in the same patch as tomatoes or potatoes, 'cos they just don't get along! Also, crop rotation is a big deal, so wait two years after planting other members of the pumpkin family (including cucumbers, melons, squashes and zucchinis) before you whack in your pumpkins. This just helps cut down the risk of disease and bad stuff happening to your pumpkin patch.

Eat me!

Pumpkin Curry

This is the ultimate in kinship. This sauce and pumpkin go together so well that you’ll pass this recipe on through the generations.

Preheat oven and bake the pumpkin while the sauce cooks. Wash and cook some jasmine rice too. Cut up and stir fry a few greens to complement it if you so desire.

Pumpkin Curry Sauce

1 onion
1 tbsp vegetable or peanut oil
1 clove garlic
2 cm knob ginger
½ butternut pumpkin or about 500g other pumpkin
1 can coconut cream or milk
1 tsp garam masala
2 chopped chilies
juice of half lemon or lime
1 star anise
1 tsp brown or palm sugar
1 tsp soy or fish sauce

Preheat oven to 200°C
Prepare rice and place it on to cook. (The absorption method is best)
Peel pumpkin. Cut into small chunks. Place pumpkin on greased baking trays and bake until tender. (Will take approximately as long as the rice and the sauce or 25-30 minutes).
Finely dice onion and chilies.
Crush garlic and grate ginger.
Heat oil in small saucepan over medium heat. Cook onion until soft.
Add garlic, ginger, chilies and garam masala. Stir for 1 minute until fragrant.
Add remaining ingredients and bring to boil. Turn heat to low and simmer gently until rice is cooked and pumpkin tender. However, the sauce will thicken quite a lot, so keep an eye on it.
When sauce is the thickness you desire, or the rest of the meal is ready, turn the sauce off. Allow to sit for a few minutes.
In this time, you could stirfry some greens. A green salad with Asian inspired dressing also goes well with this dish.
Remove star anise from sauce. Taste sauce and season if necessary.
Place pumpkin on top of rice and ladle the curry sauce on top. Serve by itself or alongside your greens.

Citrus Leafminer

Describe yourself: I’m the tiny larvae of a beautiful silver moth, and am very rarely seen. That said, you can sure see my silvery trail of destruction, as I leave my squiggly tunnels all over the leaves of your favourite citrus trees!

Hobbies: Mama moth loves laying eggs on your fab citrus foliage, and can produce up to 15 generations of lovely leafmining larvae each year. Lovely larvae live to mine, and this produces some super squiggly silver tracks all over the leaves of your citrus

Likes: I adore citrus trees of all kinds, especially lemons, limes (native and exotic) and orange trees. I love laying eggs, especially on the midrib of the foliage of your favourite fruit trees, and knowing my beautiful larvae are growing big and strong inside your foliage. I especially like when all my babies make their silvery tracks on your leaves…..it makes a mother so proud!  And I love to get started when there is fresh new foliage available.

Dislikes: Parasitic wasps and lacewings really bother me, as do a number of low environmental impact horticultural oils. Diligent gardeners who pull off and dump infested leaves into the bin also make me sad.

You’ll know you’ve met me when: The leaves of your citrus are covered in squiggly silver trails, and, if the infestation is pretty bad, the leaves may appear to curl and become distorted. These curled leaves allow my larvae to pupate and become grown ups....ready to fly and infest again!

Old School Control Methods: Really hideous chemicals registered for commercial growers only.

Breaking up ain’t hard to do… if:

  • Remove all affected leaves as soon as you see them. This means inspecting new growth, especially in spring.  Although moth numbers are low then, new growth, especially on young trees, is much more vulnerable.  The mines are not as obvious as later in the season, but if you inspect trees closely and see about 10% of leaves with mines, the leaves should be removed.  Place the removed foliage into a plastic bag and leave it out in the sun, or dispose of it in the bin. Do not compost these leaves, otherwise your compost bin may become a nursery for more leafminer!
  • Encourage natural predators like lacewings and parasitic wasps to your garden by increasing your backyard biodiversity. Otherwise, consider purchasing some of these guys where all good bugs are sold!
  • Spray with horticultural oil to deter mama moth from laying new eggs. The oil won't kill the larvae which is why it's important to inspect trees early in the season and remove any infested growth. Spray first thing in the morning to avoid spraying beneficial insects which are less active at this time. This also reduces the chance of burning foliage. Have a look at the Garden Product Guide - Safe for You 'n' Nature for a number of suitable low environmental impact products.

Mealybugs

Hi, my name is: Mealybug

Describe yourself: I'm about 4mm long, and I'm a real sweetie, covered in a lovely layer of white powder. Although I may look cuddly, I'm a really hard worker, and enjoy hanging out with my mates on the cool undersides of leaves and stems.

Hobbies: I love nothing more than sucking sap from leaves and stems! Exuding honeydew is a special talent, which encourages sooty mould. I also release toxic saliva that can seriously damage plants.

Likes: Citrus plants, orchids, ferns, loads of ornamental plants and shade houses. I like warm and humid weather... it just makes me want to breed! Oh, and I love ants, they really look out for me!

Dislikes: Being scrapped off a plant with a stick, home made veggie oil soap mixes or store bought alternatives. I really don't get on with parasitic wasps and Ladybirds.

You'll know you've met me when: New growth on your plant looks weird and the plant has a sprinkling of white furry stuff on leaves. You can also see me and my mates hanging out along the veins of leaves and on stems.

Breaking up ain't hard to do... if you:

    • Stop my ant friends from coming around by growing tansy or other ant repellent plants! Ants tend to our every need and protect us from garden bullies. Without their protection we are all alone in the world.
    • Irritate me by putting a flattened square of aluminium foil around the base of plants to bounce light on the undersides of leaves.
    • Spray me with a home made garlic or chilli soap. Or even a store bought insecticidal soap and target the undersides of the leaves.
    • Spray your plants' leaves with water and knock me and my mates right off our perch!

  • Pay your neighbours kids to come round and wipe me off with a stick!
  • Buy some Ladybirds or Parasitic Wasps, and release them onto the infected plants.
  • Use plants that have a milky sap or furry leaves... we hate them!
  • Dab us with rubbing alcohol or methylated spirits…..man, that burns (but it won't harm your plants).

September In Your Patch

September is a fantastic time to be alive for us gardeners! The chill is almost gone from the mornings, and the afternoons are getting longer. Blossoms are bursting and you can smell spring in the air wherever you go. If you have been hibernating through winter now is the time to get out and into it. Read on for some fabulous September gardening advice for your area.

Improve Your Soil
Prepare your Yummy Yard for spring planting by improving your soil. Lightly dig over the soil popping in plenty of organic matter including top-notch compost and well rotted manure. Don't forget to mulch the beds with a straw mulch. This bed will be awesome come planting time... and you will have the greatest Yummy Yard in the street!

Try some colour
Why not try some lovely colour in your patch as well like nasturtium, snapdragons, phlox, petunias, marigolds (French) and celosia. They are great at attracting pollinators and beneficial insects to your patch, and they look fantastic as well. Now is the time to plant some sunflower seeds. Find a sunny spot where you would like to see some happy sunflowers later in the year and plant the seeds to double the depth of the seed. Cover lightly with dirt and wait... they'll be popping their heads up in no time!

Citrus Gall Wasp
Check your citrus trees for gall wasp and remove affected sections by pruning well below the gall. Don't compost this or put it in the green waste bin.  It's a good idea to cut through the gall to expose the larvae to air - which they hate - before putting it in a bag and popping in the rubbish bin.  Or you could soak the galls in water for a week or two - or burn them (if your local Council permits).

Other things you can do are to hang sticky yellow traps on the tree in mid-August as they attract and trap the emerging adults, but make sure you take the traps down by November as they also kill beneficial insects.

Do not use a fertiliser that is high in nitrogen, as this promotes soft growth which provides ideal conditions for the wasp.  Use a balanced fertiliser or compost.

A biological form of control - introducing wasps that prey on citrus gall wasp - is used in orchards and home gardens. Megastigmus brevivalvus and Megastigmus trisulcus are natural enemies of citrus gall wasp. They lay their eggs inside the eggs of the citrus gall wasp and when their eggs hatch they destroy the host.

Megastigus brevivalvus is sold to home gardeners in some states, but it is only available for a two-week window around October/November. If you are able to get some of the parasitic wasps, they must be released soon after the citrus gall wasps have emerged.

This is your absolute last chance to do something about gall wasp before they hatch out and take over the world, so don't put action off!

Mulch Now!
Top up mulch on your veggie patches, herb gardens and ornamental beds. Choose a sustainable, low environmental impact mulch, one that will enrich your soil as it breaks down.

Look after your tools
On really cold days, why not head out to the shed and sharpen, clean, oil and maintain your garden tools. Sounds tedious, but it's really rewarding, and will save you cash and plant illness in the long run.

Indoor Plants
Now is a great time to re-pot your Indoor Plants. Give them a bit of a feed with a seaweed tonic afterwards to keep them happy.

Below you will find more information that is specific to different regions and climates in Australia.

Warm Areas

Frost free or occasional light frosts (North from about Coffs Harbour and all the way across to the west to Geraldton)

  • Spring into it! There is so much ready to go, so why not plant some rocket, silverbeet, spring onions, Chinese cabbage, mizuna, lettuce, tatsoi, zucchini, pumpkin, leeks, capsicum, cucumber, eggplant, tomatoes and watermelon.
  • In the herb patch, pop in some parsley, sweet basil, chamomile, dill, coriander, marjoram, oregano, catnip and thyme. Also try mint, but keep it in a pot, as it has a tendency to take over.
  • Feeling fruity? It's time to plant passionfruit, paw paw, avocados, banana, citrus and macadamias. If your tastes are a little more exotic, try putting in a guava... they're tough plants and the fruit is sensational!
  • Consider a green manure crop to add some life and love to an overworked patch. At this time of year, try millet, lablab, amaranth or mung bean. This will improve your soil incredibly and you'll find it well worth the effort! Green manure crops like faba beans, barley, lupin, wheat or field peas are also good to go now.

Cool to Cold Areas

Low temperatures for extended periods of time (all of Tasmania, most of Victoria, the southern highlands of NSW, the ACT and a tiny southern bit of SA)

  • There's a bit happening in the veggie patch so you could try leeks, onions, parsley, parsnips, cauliflower, peas, radish, silverbeet, lettuce, swedes and turnips. Don't you just love the start of spring?
  • Don't get over excited... it's too early for tomatoes just yet!
  • In the herb patch pop in some chamomile, dill, coriander, echinacea, catnip and thyme. Also try lemon balm but keep it in a pot, as it has a tendency to take over! Plant these after the frost risk has passed.
  • Green manure crops like faba beans, barley, lupin, wheat or field peas are good to go now... improve that dormant veggie patch!

Temperate Zones

Occasional winter frosts (pretty much the rest of Australia, most of the inland, some areas of Victoria, most of SA and the southern area of WA)

  • Leap into springtime gardening, especially in your veggie patch! Try celery, silverbeet, lettuces, leeks, spring onions, climbing beans, cucumber, sweet corn, tomato, carrot, Jeruslaum artichokes and radishes. Wait until the frosts have finished.
  • Get into herbs in the 'burbs with parsley, chives, catnip, sage, oregano, rosemary, thyme and marjoram.
  • Feeling fruity? It's time to plant blueberries, passionfruit, paw paw, avocados, banana, citrus trees, olives (non-weedy varieties). If your tastes are a little more exotic, try putting in a guava... they're tough plants and the fruit is sensational!
  • Green manure crops like chick pea and barley are good to go now... improve that dormant veggie patch!

Of course, this is just a rough guide, and many of you will find your situation varies from the above due to microclimates created in your garden, location in relation to your nearest major city, extremes of weather and garden type.

Happy springtime gardening, see you next month!

Aphids

Hi, my name is: Aphid

Describe yourself: I'm a real softy, small in size (around 2 - 3mm), with a shiny, transparent green or yellow body! I occasionally dress up in a white, woolly coat. I'm rarely seen on my own as I hang out in a pretty big group!  A particular version of me, the cabbage aphid, is more grey and particularly loves brassicas in winter.

Hobbies: Multiplying!!! Sucking sap; exuding honeydew; hanging out with ants which are attracted to the honeydew, encouraging sooty mould and passing viruses from plant to plant.  You'll often find yellow patches from these viruses on infected leaves.

Likes: Yellow flowers, warm moist environments, succulent new growth of just about every kind of plant (I really love roses, heaps of veggies, annuals and citrus trees).

Dislikes: Chives, coriander, garlic, onions, petunias and radishes. Soaps - like home made chilli soap, neem oil (Azadarachtin).  Don't get along with Ladybirds or Lacewings, Braconid Wasps, Hover Flies or Praying Mantis! Oh, and I hate sticky traps!  These predatory insects seem to be attracted by companion plants like Alyssum, Yarrow and Dill.

You'll know you've met me when: all your plants' new growth is seriously malformed; there are heaps of ants on the stems or plant parts are sticky from my honeydew. Oh, and yucky black sooty mold soon appears!

Breaking up ain't hard to do... if you:

  • Squash me and my mates by hand. It's icky but effective! Or pay your neighbours' kids to do the deed- they love squashing us!  In my death throes I emit a chemical signal that makes the other aphids take off quick smart!
  • Stop my ant friends from coming around by growing tansy or other ant repellent plants! Ants tend to our every need and protect us from garden bullies. Without their protection we are very vulnerable to being eaten!
  • Irritate me by putting a flattened square of aluminium foil around the base of plants to bounce light on the undersides of leaves.
  • Spray me with a home made garlic or chilli soap. Or make an insecticidal soap (2ml liquid Castille soap per 100 ml water) and target the underside of leaves.  Some claim that including mint tea in the water can also be helpful.
  • Suck me off with a vacuum cleaner.
  • Spray your plants' leaves with a strong jet of water (either with a hose or kitchen spray bottle) and knock me and my mates right off our perch!
  • Provide a bright yellow plastic dish, half filled with water, near my preferred plants.  I can't resist yellow things, but I can't swim either! You can work out the rest!

Produce in Pots

Plants in pots... it’s hardly a new or revolutionary concept... I mean, we are all well acquainted with the potted Maidenhair fern in the bathroom, a dusty 'Parlour Palm' struggling for life in the corner of the office, or the ubiquitous 'Peace Lily' given as a gift when we can’t think of anything better. But what about productive plants in pots? Imagine a 'movable feast' in your inner city courtyard, providing a fair amount of the food you love to eat? A bounty of beautiful herbs out by the BBQ, or tonnes of tumbling tomatoes at your townhouse? Just about anyone has room for a few pots at their place, and we reckon you will be amazed by just how much produce you can grow in just about any space!

Gone to Pot – Getting Started

Planting a productive potted plot is no different to getting going in a garden – it’s all about planning, position, potting mix, patience and productivity.

Position

This is all about the best position, not just for your plants, but for you as well.  Almost all edible plants will do best in a full sun spot, so spend a bit of time in your patch, and work out where the sun is at it’s most super!  Remember, this will vary considerably from winter to summer... but the beauty of planting in pots means you can move them as required to catch the rays!  Pop the pots somewhere convenient for you – the closer they are to the house, the more likely they are to be watered (very important) and eaten (also very important!).  Make sure that the pots are not blocking access ways, are not sitting in wind tunnels, and are not in the firing line of dogs, cats and wayward balls.

If you just can’t get the right pot position, why not consider going up, rather than down? There is a massive range of tasty treats that can be grown in hanging and wall pots, and this is often an excellent solution for light starved courtyards, or those spaces dominated by our little fur babies (yes, dogs and cats are cute, but they can be a gardener's nightmare!).  Turn the old Hills Hoist into a harvestable haven, or the side fence into a fresh food feast – they make excellent backyard features, and you’ll be the talk of the neighbourhood (in a good way)!

Planning

Containers look best when they're grouped together, with pots of all different shapes and sizes closely clustered.  It has a greater visual impact, cuts down on watering, creates some mini biodiversity and means you don't have to walk so far to enjoy a plethora of plants.  Group plants that require similar levels of watering together, bearing in mind that plants in terracotta pots will dry out a bit faster than others.  We know that pots can be pricey (no-one works in horticulture for the money), but check out our Renters Guide To Sustainable Gardening for some great tips for procuring pots.  The secret is to never let a pot pass you by... if you see a bargain (or even better, a freebie), grab it, you can always use it for something.

Potting Mix

As anyone who knows me will tell you, I have an unhealthy obsession with healthy soil (which is not a bad thing in itself, but does tend to make fairly boring dinner party conversation).  When planting productive pots, the growing medium is incredibly important, but the hot tip here is NOT to use garden soil in pots! Healthy garden soil contains a fantastic mix of microbes, bacteria, fungi and worms... which are great in the garden, but generally don’t perform that well in containers.  Garden soil in pots can often have significant drainage issues, and tends to go shabby pretty quickly.  The secret to awesome pots is to use a certified organic potting mix, and thankfully, there are now plenty of them around.  When opening bags of potting mix, it is important to be aware of the potential for harmful airborne critters to puff out of the bag and into your respiratory system, so consider wearing a mask, and wetting down the potting mix before handling.

Good organic potting mixes will break own over time, so you will need to refresh the pots with new potting mix every so often.  Oh, and don’t forget to mulch the tops of all pots with a straw based, locally sourced mulch, to slow down water loss, and prevent weed infestation.  As this stuff breaks down, your potting mix will be enriched with natural goodness, minimising the need for additional feeding, saving you both time and money.

Patience...

...is a virtue, so my mother tells me, but this is not always an easy thing to remember in the garden. Consider staggering the planting times of some of your edible favourites (that is, don’t plant 15 tomato plants at once), to prolong the harvest and therefore maximising the yield of your pots. Growing from seed is an excellent way to do this, and while it may be a slightly longer and more tedious process than using seedlings, the extended harvest and money saved may just make it worthwhile for you.  Plus, you can often collect and save the seed from many herbs and vegies from one year to the next, which is a good thing for the back pocket, and the planet. Use heirloom varieties whenever possible to ensure the seeds will be viable.

Productivity

Edible gardening is all about maximising productivity, and this is especially important in small space and container gardens.  The secret is to plant what you want to eat, and be familiar with plant families and Companion Planting. Depending on the size of your pot, you can often plant a number of different varieties of plant in the one container.

Here are a few suggestions for some winning containerised combinations!  Use these as a guide, remembering, the bigger the pot with these the better.  If your pots are a little small, use these combinations as suggested plantings for groups of pots... they’ll look great, and you’ll be amazed at just how many incredible edibles you’ll be able to fit into even the smallest space!

The Pasta Pot – One or two tomato plants at the back of the pot. Underplant these with some basil seedlings and a couple of marigolds. At the front of the pot, plant some trailing thyme, marjoram and / or oregano. These will soften the edge of the container, and mean that everything required for a perfect pasta or pizza is in one pot!  Plant this pot in spring / summer.

The Stir Fry – Underneath a Kaffir or Tahitian lime in a pot, plant some pick and come again Asian Greens (like Tatsoi, Bok and Pak Choi), and pop in some slow bolt coriander as well. If you don’t have a lime tree, why not use some snow peas as the vertical planting instead?  Grow these up a 'teepee', and underplant as above.  Plant this pot as required in autumn / winter.

The Kickin’ Curry Container – For any lover of home made curries... this container is a cracker!  In spring / summer, pop in an Eggplant (or two, if using the smaller Thai eggplants) at the back of the pot. These will need to be staked. Underplant with a Chilli, Spinach, Coriander, and a Curry plant or two, and you are set to whip up a super curry in a hurry.  Try this around September.  For a winter version replace the eggplant with cauliflower and the spinach with kale. Too easy and darned tasty!

The Season-All – This is a must have for any container gardener.  A bay tree in a nice big pot forms an attractive (but somewhat slow growing) centrepiece, surrounded by rosemary (either standard or trailing), thyme, tarragon, parsley and marjoram.  Once planted and established, you’ve got yourself an incredibly attractive, fairly drought tolerant, semi-permanent pot planting that will add interest both to the garden, and to your cooking!  Plant in spring / summer... and enjoy for ages!!

The Hot-Hot-Hot Pot - In a nice big pot (think half wine barrel size), pop in a capsicum at the back of the pot (remembering it may need to be staked).  Whack in a couple of trailing cherry tomatoes, a chilli or two (experiment with these, there are some real winners) and some marigolds for colour and companionship!  If you are so inclined, whack in some chives, and you’ve got yourself an instant Mexican feast in a pot!  Plant in spring / summer.

The Super Salad – This one is all about the lettuce, particularly the varieties that can be picked from continuously through their growing period.  Lob in some Lettuce under a teepee of peas, and pop in some rocket, silverbeet (or spinach depending on the season) and some chives, and you’ve got yourself the fixings of a nice, green salad!  Can be planted all year round, just keep the water up to this thirsty pot.

The BBC – Build a teepee, and plant a climbing bean or two. Underplant this by popping in a couple of cauliflower and broccoli seedlings, leaving about 30cm between them.  Interplant with a sage or two, and some dill.  These will enhance the flavour of the broccoli and cauliflower, and help keep Cabbage White Butterfly at bay.  Plant between April and August.

The Happy Apple – Miniature or 'Ballerina' apple trees are fantastic in pots, and with the right pollinators nearby, they can be incredibly productive.  Underplant these trees in pots with some nasturtium and chives, and you will have yourself a happy potted apple.  Plant anytime.

The Hanging Garden – There are so many great varieties of herbs and vegies that will do well in hanging baskets, but here are a few of my tried and true favourites: Strawberries, Tomatoes (in particular the cherry and “pot tumbler” varieties), thyme, marjoram, oregano, prostrate rosemary, mint and chamomile.

While these suggestions are awesome (if I do say so myself), they are by no means the only combinations possible.  Remembering the principles of backyard biodiversity and companion planting, you too can come up with your own cool containerised combination!
