Sowing

Seed is fine and needs light: surface-sow into trays 8 to 10 weeks before planting out (Johnny's, Iowa State) and cover only enough to hold it in place.

Care and transplanting

Pinch seedlings for branching. Plants tolerate light frost; NDSU transplants them about 2 weeks before the last frost.

Problems

Slow, tiny seedlings are normal for the first month. Keep the surface just moist.

Saving seed

Collect the rattling seed pods when dry; hybrids do not come true.
