Neem oil is a natural solution for protecting your tomato plants from pests. Derived from the seeds of the neem tree, it acts as an insect repellent and disrupts the life cycle of many common garden pests. To use neem oil effectively, mix it with water and a few drops of dish soap, then spray it on your plants. This method helps keep your tomatoes healthy and pest-free.

It contains azadirachtin, a compound that interferes with the hormones of insects, preventing them from feeding, breeding, and growing. This makes neem oil an effective deterrent against a wide range of pests, including aphids, whiteflies, and spider mites, which are common threats to tomato plants.
