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.
Spread a tarp or blanket under the chestnut tree when the nuts begin to drop from it in early fall. Cover the ground beneath the entire canopy to collect as many nuts as possible over the two- to four-week harvest window.
