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.
Place the seed in a fairly shallow hole. Dig a hole roughly 1 inch (2.5 cm) deep. Place the chestnut seed in the hole and cover loosely with additional soil or planting mix. Since most chestnuts will have sprouted before you plant them, make sure that the sprout is face-down when you plant the nut.
