The story
Chestnuts were the bread of mountain Europe and Japan for centuries, ground into flour where wheat would not grow. The American chestnut, once a quarter of the Appalachian forest, was wiped out by blight after 1904; Chinese and hybrid chestnuts carry the resistance that lets the nut come back.
Planting
Full sun, acid to neutral drained soil, and two or more trees for pollination; they are wind-pollinated. Plant in spring; grafted or seedling Chinese and hybrid types bear in four to six years.
Growing
Water young trees, mulch, and prune to a single leader. They dislike lime and wet feet. The June flowers have a strong smell.
Harvest and use
Burs open and drop in early autumn; gather daily before squirrels do, wearing gloves. Cure a week in a cool place to sweeten, then roast, boil or dry.
What to watch for
Chestnut blight on susceptible trees, chestnut weevil, and gall wasp where present.
