The story
Japanese chestnuts have been gathered and planted in Japan since the Jomon period. Kuri gohan, rice cooked with chestnuts, marks autumn, and the trees' resistance to chestnut blight made them a parent of many blight-tolerant hybrids.
Planting
Full sun, well-drained acid soil. Plant two different trees for pollination.
Growing
Fast to bear, often in three to five years. Prune lightly in winter.
Harvest and use
Collect nuts as the spiny husks split in autumn; roast, boil or cook with rice.
What to watch for
Spiny husks: wear gloves. Needs a second tree nearby for good crops.
