The story
Oats began as a weed in fields of wheat and barley and became a crop of their own where summers were too cool and wet for the others. They fed the people and horses of Scotland, Ireland and Scandinavia for two thousand years.
Planting
Full sun and ordinary soil. Sow in early spring, or in late summer as a cover crop that frost will kill.
Growing
They need little beyond rain. Hull-less varieties save you the work of threshing off a tight husk.
Harvest and use
Cut when the heads turn gold and the grain dents under a thumbnail. Dry the sheaves, thresh, winnow, and roll or cook the grain whole.
What to watch for
Tall plants fall over in rich soil. Birds find the ripening heads.
