How to Care for the Plant
Water
Young seedlings require regular irrigation. If you are growing chestnut trees for the nut production, however, you’ll need to provide more chestnut tree care. The only way you can be sure of getting abundant, large-sized nuts is if you water the trees regularly throughout the growing season.
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.
Sunlight
For nut production, chestnuts need full sun. Period. The trees will grow faster, however, with about 30 percent shade. Under these conditions, chestnuts can grow four to seven feet per year—about twice as much as those in full sun.

Soil
All chestnut tree types require well-drained soil to thrive. They can grow in partially clay soil if the land is on a slope, but they will grow best in deep, sandy soils. Be sure your soil is acidic before growing chestnut trees. If you aren't sure, get the pH tested.
