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.
A good method for storing freshly harvested chestnuts in a refrigerator is to use milk cartons and dry peat moss (as it comes from the package). If the chestnuts are separated by the dry moss and the package tightly closed, the nuts should stay in good condition for several months. Freshly dug sand can also be used.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).
