Growing Meyer lemons can be a rewarding experience, but like all citrus trees, they are susceptible to pests and diseases. Neem oil is a natural and effective solution to protect your trees without resorting to harsh chemicals. However, using neem oil safely is essential to ensure the health of your lemon trees and the safety of your environment.
What is Neem Oil?
Neem oil is derived from the seeds of the neem tree (Azadirachta indica), native to India. It has been used for centuries in traditional medicine and agriculture due to its insecticidal and antifungal properties. Neem oil works by disrupting the life cycle of pests and preventing fungal infections, making it a popular choice for organic gardening.
