The story

Korean pine nuts have been gathered in the forests of Manchuria, Korea and the Russian Far East for thousands of years by Nanai, Udege and Korean villagers, who climbed the trees for cones; they are the pine nuts in most Asian markets and the staple food of the Siberian tiger's prey.

Planting

Full sun or light shade, drained acid to neutral soil, and a cold climate; slow, to 50 feet. Plant young and give it 20 years.

Growing

Water the first summers, mulch, and leave it. No pruning. It is hardier than any other nut pine.

Harvest and use

Cones ripen in early autumn in good years; gather, dry until they open, and crack the big nuts. Squirrels compete hard.

What to watch for

Squirrels, white pine blister rust where currants grow nearby, and the wait.
