Propagate by seed

Germination temperature: 40 F to 55 F

Days to emergence: 5 to 7

Seed can be saved 5 years.

Seeds germinate quickly even in cold soil. Plant as soon as soil can be worked in spring.

Avoid planting after other cabbage family crops.

Plant ¼ inch deep and 1 inch apart in rows, or broadcast alone or mixed with other greens. Gradually thin to 6-inch spacings using thinnings for salads.

Make new plantings every 2 to 3 weeks for a continuous supply until about a month before your average first frost date.

Slow bolting by reducing heat and moisture stress. Provide some shade for warm-season plantings.

Fast-growing plants are good for intercropping and relay cropping.

Often self-seeds. Is self-sterile and requires insects for pollination. Will not cross with other members of the mustard family.

Flea beetles

Rarely a problem.
