FAQ

When do you harvest chestnuts?
Chestnuts ripen between late September and October, falling naturally when the spiny burr opens. Harvest with thick gloves due to the sharp spines of the burr.
What is the difference between chestnut and horse chestnut?
Chestnut (Castanea) produces edible sweet nuts; horse chestnut (Aesculus) produces similar but toxic seeds of a different species. Tell them apart by leaves: lanceolate serrated vs palmate.
