Sweet edible chestnut trees for sale. I only have a few left. These beautiful trees will grow to make sweet chestnuts. It is advisable to purchase 2 trees so that they can pollinate each other and get a bigger yield and a bigger nut. When they grow, they will make beautiful, sweet chestnuts. Imagine eating fresh chestnuts instead of store-bought bought, which are always rotten when you bring them home. These are fresh.
