How Often Should You Apply Neem to a Vegetable Garden?

By S.F. Heron ; Updated September 21, 2017
Neem oil offers gardeners an organic alternative to control vegetable garden pests.

Apply neem oil to vegetable garden foliage every seven to 14 days. Spray neem oil on leaves to allow the plant to absorb the product through the foliage. Insect control occurs when pests consume plant foliage. Reapply neem oil after rain or watering.
