You step out to admire your tomato plants and spot ragged leaves, pecked fruits and tell‑tale droppings. Plenty of gardeners in this situation now reach for something from the bathroom cabinet rather than the garden shed: a humble bar of soap hung near the tomatoes. Why a bar of soap ends up near tomato plantsPerfumed bar soaps often carry bold fragrances such as peppermint, eucalyptus, pine, citrus, lavender or menthol. How to use bar soap around tomatoes without harming themThe key is to use solid bar soap, not liquid products. Soap near container tomatoes or in a small greenhouse carries more risk, because any run‑off is trapped in a limited volume of compost.
