When we first start out to garden we are dismayed when our carefully tended plants suddenly look sick. But gradually we learn that, plant, like humans are subject to illness.

SGA are big fans of non-chemical disease control and prevention, such as monitoring your garden for early outbreaks, ensuring good air circulation between plants and alternative home remedies such as garlic sprays. If you choose to use a chemical, select one of the 6 Star-rated products from the SGA’s WiseGardening – Choices to Protect You and the Planet – your garden, and the planet will thank you for it.

If you do use any chemical product, please read the label VERY carefully.  And to understand what the chemical terms on labels, it’s worth looking here.
