The best fertilizer for holly trees is an acid-based variety that includes nitric acid or cottonseed oil to keep the pH level down. Fertilize the holly tree in the late fall to give it a nutritious boost before the growing season; add a layer of compost to further fertilize the plant and enrich the soil with organic matter.
