Planting Details
| Row Spacing | 24" – 36" |
|---|---|
| Seed Depth | 1/4" |
| Seed Spacing | A group of 3 seeds every 24" |
| Thinning | When 2" tall, thin to 1 every 24" |
| Germination | 8 – 10 days |
| Start Indoors | RECOMMENDED. 4 to 6 weeks before transplanting outside after your average last frost date, or 12 weeks before your average first fall frost date. In mild climates, sow in fall for harvest in late winter and early spring. Ideal soil temperature for germination is 70°–85°F, cooler (60°F) growing temperatures thereafter. |
| Direct Sow | Not recommended. 1 to 2 weeks before your average last frost date, or 10 to 12 weeks before your average first fall frost date. In mild climates, sow in early fall for winter harvest. |
| Special Care | To ensure white rather than off-white or yellow heads, you can gently tie up the leaves or bend a few leaves, breaking the mid-rib, and tuck them across the head for sun protection (blanching). |
| Growing & Harvesting | Harvest heads in the morning, if possible, and when buds are tight. Cut stalk below the head. Dunk heads in ice water to reduce any "field heat" and increase storage time. Allow to drain before storing. |
