How to Apply Neem Oil Spray for Plants: Before spraying a an entire plant, test a small area on the plant and wait 24 hours to check to see if the leaf has any damage. If there is no damage, then the plant should not be harmed by the neem oil. Apply neem oil only in indirect light or in the evening to avoid foliage burning and to allow the treatment to seep into the plant. Also, do not use neem oil in extreme temperatures, either too hot or too cold. Avoid application to plants that are stressed due to drought or over watering. Using neem oil insecticide about once a week will help kill pests and keep fungal issues at bay. Apply as you would other oil-based sprays, making sure the leaves are completely coated, especially where the pest or fungal problem is the worst.
