Do chestnut trees still exist?

Do you need two chestnut trees to produce nuts?
Make sure you have enough space for at least two giant trees before committing to grow chestnuts. You’ll also need to plan to have at least two chestnut trees planted within ~100 feet of each other (or less). This ensures that your chestnuts will be able to cross-pollinate in order to produce nuts.
Do you need 2 chestnut trees?
You must plant two trees to provide the necessary cross-pollination, so, unless your neighbor has a tree that’s a seedling or is of a different variety, always plant two different varieties. Chestnuts are primarily wind-pollinated, so the two or more pollenizers need to be within about 200 feet of each other.
