Growing Mammoth Red Rock Garden Seeds

Growing Directions:

This cabbage variety does well in warm temperatures, with full or partial sun. Sow seeds indoors five to seven weeks before the last average frost, and transplanted outside after four weeks. It is helpful for growth to add compost to the soil when planting them. When the Mammoth Red Rock plants are ready to be transplanted, sow them half an inch deep, with one and a half feet between the plants, in rows with two feet between them. Harden the plants off throughout a week-long period when transplanting them for the best results. Water plants with two inches of water each week to keep the soil moist. The heads will grow hard and around seven to eight inches in diameter when they are ready to be harvested. This will happen at around 90 days. Harvest the entire plant when you harvest the head. Leaving the stem or even root in the soil can cause diseases that will affect future crops.
