Soil
Rich, moist soil, firm with plenty of well rotted compost dug in.
Position
Full sun.
Frost tolerant
Tolerates light frost.
Feeding
Feed plants with a liquid plant food when they begin to form heads.
Companions
Basil, Celery, Dill, Garlic, Mint, Nasturtium, Potatoes, Rosemary, Thyme, Onions, Beans and Agastache.
Spacing
Single Plants: 1′ 3″ (40cm) each way (minimum)
Rows: 11″ (30cm) with 1′ 11″ (60cm) row gap (minimum)
Sow and Plant
Sow in spring while the soil is still cool. Plant again in late summer for harvesting in the fall.
Notes
Water often to keep the soil constantly moist.
Harvesting
Harvest when the heads reach the size you want. In fall, cut heads high, leaving the base of the plant intact. Small heads will often regrow from the stub.
Troubleshooting
Slugs can be a problem. Trap them with beer traps, hand pick them in rainy weather, or spray them with caffeinated coffee.
