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.
Walnut harvest usually begins in the southern and central valleys in early September and the northern regions in early October. The walnuts are ready to be harvested when the green outer hull splits exposing the nut. At this time, many walnuts have already dropped from the trees to the orchard floor. Nuts that have not dropped naturally are then mechanically shaken from the tree.
