Direct sow in weed-free, well-prepared soil March to May, during a warm dry spell if possible. Barley is usually frost tolerant down to 15 °F. Fertility and irrigation needs are very low if you have decent soil.
Harvest for grain when seeds are dry and plants are no longer green. Dance, rub, or flail seeds from seedheads. Winnow to clean in front of a fan or steady breeze.
