Definition - What does Neem Oil mean?
Neem oil is a natural way to treat pest infestations such as thrips, aphids, mites, nematodes, and whiteflies on cannabis plants. Interestingly, neem oil is not harmful to beneficial insects. It is considered an organic pesticide and fungicide. It effectively treats black spot and powdery mildew on marijuana plants and other plant varieties.
Neem oil is made from the seeds and fruits of the evergreen neem tree (Azadirachta indica) which grows in its native habitat on the Indian continent. The tree has also been naturalized in a variety of tropical locations around the world.
Hydrolife explains Neem Oil
Neem oil has been horticulturally used for centuries. Neem oil can be regularly used on cannabis plants to control fungi and pathogens that can damage the plants. It can even be mixed with water and applied to the plant’s root system to prevent and treat root rot.
When used a preventative measure, neem oil should be applied to the marijuana plant every 10 days as a foliar spray or a root rinse. Ideally, the oil should be used as a scheduled preventative measure during the plant’s growth phase.
Growers should avoid using neem oil on cannabis plants three weeks prior harvest. If the oil is used too close to harvest time, it can affect the flavor of the plant. Because neem oil is 100% natural, it is considered safe for use on medical marijuana plants.
Neem-oil is considered a non-systemic pesticide, meaning it's not absorbed by a plant and works from the inside out; rather, it is applied topically, and kills pests on contact, first by smothering them.
