Harvesting Chestnut Trees. After the chestnuts fall from the tree, watch for the spiny burs to split. Donât harvest chestnuts if the burs are still green and closed because the nuts inside will be unripe. Harvest the nuts every couple of days.
Chestnut trees will grow in partial shade but they grow slow and will not produce lots of chestnuts. Chestnut trees should be placed no closer than 25 feet apart with 30 to 40 feet being best. Chestnut seedlings started pots with potting soil can be transplanted any time after the last frost. If a chestnut seedling gets frostbit, it has a 50/50 chance of surviving.
