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.
What do chestnuts yield and how are they harvested? Under good conditions, a chestnut orchard will have its first worthwhile yield 4 to 5 years after planting. Under less than ideal conditions it may take a few years longer. Maximum production will begin after 10 to 20 years depending on spacing and genetic material.
