The Mammoth Red Rock cabbage can be sown indoors five to seven weeks before the last average frost, and transplanted outside after four weeks. The crop will need full or partial sun, and the soil will need to remain moist. The Mammoth Red Rock cabbage needs two inches of water each week while growing. When transplanting outside, it’s best to harden off the plants over the course of a week. 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. The seedlings will do best in a composted soil. At around ninety days, the heads should be firm and about seven to eight inches in diameter. When this stage is reached, the Mammoth Red Rock cabbage can be harvested. When doing this, you will need to also remove the entire stem and root, to prevent the buildup of disease.
