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.
Chestnuts dry rapidly in dry air and mold rapidly in damp air. For refrigerator storage, first place the chestnuts in a closed paper sack and leave for 1 to 2 days until they have reached refrigerator temperature.he sand should be cooled before use in the milk carton. Sand also keeps chestnuts in good viable condition for 2 years by storing the freshly picked chestnuts in sealed plastic bags and maintaining a temperature of 26 degrees Fahrenheit to 30 degrees Fahrenheit. (This temperature range requires special refrigeration).
