How to Care for the Plant
Water
Water newly planted trees regularly. Established trees require little care.
Fertilizer
Feed your chestnut tree once per year in the spring after the last frost has passed and the soil is warm enough to be worked easily and absorb the applied water and nutrients. Use a complete granular fertilizer that is nitrogen-rich and has a guaranteed analysis of 30-10-10 or 20-6-6. Apply the fertilizer to the soil surface at a rate of 1 lb. for every 50 square feet of soil surface.
Sunlight
Full sun and partial shade are best for this tree, meaning it prefers a minimum of four hours of direct, unfiltered sunlight each day.
