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.
Once you decide you have the space and penchant for growing chestnuts, here's how to get started. Your planting location should ideally be on sloping, well-drained soil in full sun. Chestnuts like a slightly acidic soil and don't tolerate heavy clay well. Plant at least 2 different varieties for cross pollination.
