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.
How to choose a good chestnut. From October to December, look for fresh chestnuts that are hard, shiny, unblemished, heavy for their size and do not rattle when shaken. Because they are highly perishable, refrigerate chestnuts in perforated plastic bags for up to one week.
