What is neem oil and how does it benefit my garden?
Neem oil is a natural pesticide derived from the seeds of the neem tree, native to the Indian subcontinent. Known for its potent properties, neem oil works by disrupting the life cycle of pests, making it effective against insects like aphids, spider mites, and whiteflies. Its active compound, azadirachtin, not only repels pests but also inhibits their ability to feed and reproduce, leading to a decrease in pest populations.
Besides pest control, neem oil has antifungal properties that can help in managing plant diseases such as powdery mildew and root rot. By incorporating neem oil into your gardening routine, you can create a healthier environment for your plants by reducing the reliance on synthetic chemicals, promoting biodiversity, and supporting a more sustainable gardening practice.
How do I mix neem oil for effective use?
To mix neem oil for garden use, start with a base of high-quality, cold-pressed neem oil.
