Staying on top of pests and weeds without using synthetic treatments isn’t always easy, but it is most rewarding for organic gardeners to overcome the challenge using garden know-how and good old-fashioned elbow grease.
Companion planting, the process of positioning plants that aid neighbouring plants, can be used to help reduce pests. If you want to vanquish whitefly, for instance, plant some marigolds.
Blackfly and greenfly can be kept in check with the use of neem oil or use washing up liquid to eradicate aphids.
For weeds, I find it’s best to just pull them up. Annual weeds, those growing fresh each year, can be easily controlled with a hoe as this cuts the tops off, but perennial weeds, which come back each year – like dandelions and nettles, should be pulled up by the root—the secret is to do this little and often to regain control.
