January In Your Patch
What’s happening in the garden this Month?
January can be one of the toughest months in the garden. Heatwaves, drying winds and holiday absences can all place extra pressure on plants. The good news is that a few simple actions can keep your patch productive, resilient and thriving through summer.
This Month’s Priorities
Protect plants from heat
January sun can be relentless, especially for young seedlings, leafy greens and recently planted crops. Set up temporary shade cloth, umbrellas or other moveable shade structures to protect vulnerable plants during extreme heat. Position shade on the western side of garden beds to block the harsh afternoon sun. If you’re looking for a longer-term solution, try growing climbers such as cowpea or climbing beans over a trellis to create living shade while also improving soil healt
Water wisely
Give your garden a deep soak in the early morning a few times a week rather than light daily watering. Deep watering encourages roots to grow further into the soil, helping plants access moisture during hot weather. Before forecast heatwaves, water thoroughly to build up moisture reserves in the root zone. Keep an eye on pots and hanging baskets, which dry out much faster than garden beds and may need extra watering.
Top up mulch
A generous layer of mulch is one of the best ways to protect your garden through summer. After watering, top up mulch around vegetable beds, herbs and ornamentals to around 7cm deep, keeping it clear of stems and young seedlings. Mulch helps reduce evaporation, moderate soil temperatures, suppress weeds and improve soil structure as it breaks down.
Support wildlife
Hot weather can be just as challenging for birds, pollinators and other wildlife as it is for plants. Place shallow dishes of clean water around the garden and add stones, sticks or non-slip surfaces so insects can drink safely. Raised bird baths help protect visitors from cats, while flowering plants and diverse habitats provide food and shelter for beneficial insects that support a healthy, balanced garden ecosystem.
Watch for pests
Warm weather creates ideal conditions for a range of summer garden problems. Protect tomatoes, capsicums and eggplants from Queensland fruit fly with insect exclusion netting, and regularly collect fallen fruit to reduce pest numbers. Keep an eye out for blossom end rot on tomatoes, which appears as a dark, sunken patch on the bottom of fruit and is often linked to irregular watering. Regular checks now can prevent bigger problems later in the season.
What to Plant in Your Region
Warm Areas
Rarely experience frost, or only very light frost. Includes northern coastal and inland regions, generally north of Coffs Harbour across to Geraldton.
January can be challenging in warm climates, with high temperatures and intense sun placing stress on young plants. While it’s not the busiest planting month, there are still plenty of productive options for your patch.
Edibles to plant now: Eggplant, zucchini, cucumber, capsicum, chillies and tomatoes can be planted now, with late January often providing the best planting window in many regions. Lettuce can also be planted towards the end of the month but will benefit from some afternoon shade or protection under shade cloth.
Herbs: Lemongrass thrives in the heat and is an excellent choice for summer planting.
Fruit: It’s not too late to plant watermelon and rockmelon, while longer-term crops such as pineapple and mango can be established now for future harvests.
Flowers: Marigolds and sunflowers add colour to the garden while attracting pollinators and beneficial insects.
Soil Builders: Sow heat-loving green manure crops such as cowpea, lablab and millet to protect bare soil, improve structure and boost fertility. Climbing varieties can also provide temporary shade for young vegetables.
Cool to Cold Areas
Frequent frosts and cooler summers. Includes Tasmania, the ACT, Southern Highlands of NSW, southern Victoria and parts of southern South Australia.
Although summer temperatures are milder than other regions, January is still a productive time for planting and maintaining your garden.
Edibles to plant now: Lettuce, spinach, silverbeet, spring onions and leeks can all be planted now for reliable harvests over coming months. Zucchini will also perform well provided plants receive adequate sunlight and watering.
Herbs: Basil, parsley, dill, sage and watercress can all be planted now. Mint is another great option but is best grown in containers to stop it spreading. Avoid planting coriander, which is likely to bolt quickly in summer conditions.
Flowers: Plant stock, verbena and ageratum for summer colour, or sow sunflower seeds in a sunny position for cheerful blooms later in the season.
Soil Builders: Green manure crops such as millet and mung beans will help restore nutrients, build organic matter and improve soil structure ahead of autumn planting.
Temperate Areas
Occasional frosts in winter and warm summers. Includes much of southern Queensland, southern NSW, inland South Australia, Victoria and parts of Western Australia.
January remains an active planting month in temperate regions, although extra attention to watering and shade may be needed during hot spells.
Edibles to plant now: Leeks, sweet corn, beans, cucumbers, spring onions and zucchini are all suitable choices and will keep the patch productive through summer.
Herbs: Lemongrass is one of the most reliable herbs to establish during the hotter months thanks to its tolerance of heat and dry conditions.
Flowers: Sunflowers are a classic January planting. You can also add colour and attract beneficial insects with nasturtiums, verbena, petunias and marigolds.
Soil Builders: Consider sowing green manure crops such as cowpea, mung bean, soybean or millet to improve soil health and prepare beds for future crops.
Summer Care: Keep mulch topped up, maintain a regular watering schedule and remove weeds before they compete with your vegetables for moisture and nutrients.
Build Healthy Soil This Summer
January is a great time to focus on soil health. Healthy soil holds moisture more effectively, supports stronger plant growth and helps gardens cope with summer heat.
Feed Your Garden
Plants are actively growing and producing fruit at this time of year, so they will benefit from a gentle feed. A seaweed solution or low environmental impact liquid fertiliser can help support growth, improve resilience to heat stress and encourage healthy root development. Worm tea can also be applied every couple of weeks throughout the growing season to boost soil life and plant health.
For best results, apply liquid feeds to moist soil early in the morning and follow the recommended dilution rates.
Grow a Green Manure Crop
If you have empty garden beds, consider sowing a green manure crop. Fast-growing plants such as cowpea, lablab, millet, mung bean or soybean help protect bare soil, suppress weeds and add valuable organic matter when dug back into the garden. Green manure crops also support beneficial soil microbes and can improve soil structure for future plantings.
Climbing varieties such as cowpea and lablab can provide the added benefit of temporary shade for young vegetables during the hottest part of summer.
January isn’t just about surviving summer. It’s the perfect time to observe your garden closely, learn what thrives in your conditions, and start planning for the productive seasons ahead. Even a few minutes in the cool of the morning can help keep your patch healthy and connected to the rhythms of the year.
