Dunstan Chestnut™ seedling trees are the best and most widely planted chestnut trees in America – they combine the excellent nut quality and tree form with blight resistance. Dunstan chestnut trees have been grown successfully from Maine and New York, west to Illinois and Wisconsin, and south to east Texas and Florida. They are excellent for commercial and backyard orchards, and are the best tree to plant for attracting deer and wildlife. Dunstan Chestnuts™ can produce nuts in only 3-5 years of age depending on care and climate. Trees planted in colder regions such as USDA zone 5, may bear between 5-7 years of age. The best location is a south slope, with good air and water drainage – avoid frost pockets. A sheltered north-facing slope protected from drying winds and low sun of winter may be better for cold windy sites. They produce heavy annual crops (never skipping a year like oaks) of very large, sweet tasting (no tannin) nuts that average 20-35/lb in size, and can produce 20 lbs/tree after only 10 years, and as much as 50-100 lbs/tree at maturity. They are easy to grow and thrive in a variety of locations. Cold hardy to USDA plant zones 5-9, require a minimum 300 chill hours for the chestnuts to ripen. Make sure your area is receiving the minimum needed chill hours. *Your trees might need to be gently pruned to fit in the appropriate sized box. This will not affect the health or hinder nut production. Click for Learning Center: Dunstan Chestnuts
