Step-by-step on how to plant Cabbage red Cabeza Negra
- Sow cabbage seeds a ½ inch deep spaced 1 inch (2.5cm) apart; thin plants to 18 to 24 inches (45-61cm) apart.
- Transplant cabbage to the garden when plants are 4 to 6 weeks old with 4 to 5 true leaves.
- Set leggy or crooked stemmed plants deeply; you can bury 1 to 2 inches (2.5-5cm) of the main stem even up to just below the top two sets of leaves.
- Space seedlings 18 to 24 inches (45-61cm) apart in rows 24 to 36 inches (61-91cm) apart. You can space plants closer but the heads will be smaller at maturity.
- In early spring plant cabbage through black plastic or garden fabric set in place to warm the soil. Cut an x in the fabric to set out transplants.
- Plant succession crops every two weeks or plant seeds and transplants at the same time or plant early and mid-season varieties at the same time so that they come to harvest at different times.
- Plant 4 to 8 cabbage plants for each household member.
How to grow Cabbage red Cabeza Negra

Tips on how to care for cabbage
- Mulch around cabbage—especially in warm weather—to preserve soil moisture and keep the soil cool in warm weather.
- Cabbage heads will split when they grow too fast and take up too much water.
- To prevent this damage, twist heads a quarter turn to separate some roots and interrupt water uptake a week in advance of harvest.
- If heads are small at harvest, add nitrogen to the soil next season and plant earlier.
Watering and feeding of Cabbage red Cabeza Negra
- Cabbage requires regular, even watering. Uneven watering can result in stunted or cracked heads. Give cabbage 1 to 1½ inches of water every week; 1 inch equal 16 gallons (60.5 litres).
- As plants reach maturity, cut back on watering to avoid splitting heads.
- Fertilize cabbage at midseason when plants are established with a high nitrogen fertilizer such as 10-5-5 or feed plants a dilute solution of fish emulsion every two weeks.
Harvesting of Cabbage red Cabeza Negra
