When to harvest chestnuts? Chestnuts donât ripen at the same time and chestnut harvest time can span as much as five weeks, although the nuts generally ripen in a 10- to 30-day span of time in late August and September. Allow the nuts to fall from the tree naturally.
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).
