Encourage your plants to fend off insect pests, powdery mildew, root rot, and other common problems. Spray down the soil of indoor plants with neem oil so the roots can soak it up and deter disease and parasites. Neem oil is non toxic and doesn't leave harmful residue.

Always follow manufacturer directions when applying a neem oil product. It is best to use as much as needed for a safe application. Know before you spray whether you are working with a ready-to-spray formula or a concentrated oil with a high amount of Azadirathacin.

Neem oil is a desirable alternative to products with potentially toxic ingredients, as neem is natural, non toxic, and biodegradable. The oil is safe for humans and animals. However, do not allow neem oil or spray to make contact with skin, eyes, or ingest or breathe it in.
