You will need to follow all instructions on the bottle VERY CAREFULLY!!! Only test on a small area at first, since many plants are sensitive to Neem Oil. You wouldn't want to spray down your whole plant to have it dead a few hours later. Correct use will be key!!!
Do not spray this in bright light. Dilute to whatever it says on the package since many manufacturers will have different concentrations.
If it responds well to a small area, then you may spray the plant.
