Cabbage
Vegetable
Sow indoors beginning in late winter and transplant outdoors from 2 weeks after the last frost date to early summer. Overwintering cabbage is sown outdoors during July where winters are mild. Optimal soil temperature: 10-30°C (50-85°F). Seeds should germinate in 7-10 days.

Timing:
Sow indoors beginning in late winter and transplant outdoors from 2 weeks after the last frost date to early summer. Overwintering cabbage is sown outdoors during July where winters are mild. Optimal soil temperature: 10-30°C (50-85°F). Seeds should germinate in 7-10 days.
Starting:
Sow 3 or 4 seeds per pot, 5mm (¼”) deep, under very bright light. Thin to the strongest plant. Space transplants 45-60cm (18-24″) apart in rows 60-90cm (24-36″) apart.
Growing:
Ideal pH: 6.5-7.0.Cabbage does best in humus-rich soil amended with composted manure. Mix ½ cup complete organic fertilizer into the soil beneath each transplant. If growth slows, side dress with a little more balanced organic fertilizer. Heads of early varieties can split from over-maturity, rapid growth after heavy rain, or irrigation after dry spells. Splits can be delayed by twisting the plant or cultivating deeply next to plants in order to break roots and slow growth. Fall and winter varieties stand in the garden longer without splitting. If direct sown, add 20-25 days to the maturity date.If cabbages won’t form heads, it may be from an imbalance of too much nitrogen in the soil in relation to phosphorus. Cabbages require cool temperatures to form heads well. Hot weather can interfere with the development of heads. GerminationDays to maturity: From transplant date.In optimum conditions at least 80% of seeds should germinate. Usual seed life: 3 years. Per 100′ row: 200 seeds, per acre: 44M seeds.
Harvest:
Cabbage heads are ready when they’re firm to the touch, and when the interior is fairly dense. Heads will split when they’re allowed to overly mature. Rapid growth due to excess watering and fertility will also cause splitting of the head. Plant early, mid-season and late varieties to spread out your harvest. Late varieties tend to be better for storage or for making sauerkraut. Early (summer harvest) varieties tend not to store as well.
