Cabbage is a fairly easy plant to grow because it is a hardy vegetable.
Propagate by seed. Seeds, which germinate within four to seven days, can be started indoors in April and transplanted after about a month of indoor growth.
Transplant the young plants to their final growing position when plants have five or six true leaves, setting the lowest leaves at ground level. Water well the day before moving, firm in well after transplanting and ‘puddle’ in the plants with plenty of water (this means filling the hole with water several times before adding soil).
How to Grow in Pots
Make sure to sow the cabbage seeds ¼ to ½ inch deep. After you sow them, keep them moist and thin them out to desired spacing once they grow. Make sure you fertilize your plants when growing cabbage, especially after transplanting. Then add nitrogen or organic fertilizer as well when the cabbage is half grown. This helps them mature better. Make sure the soil is moist throughout the growing season so your cabbage produces better heads.
Cabbage grows best in soil with a lot of organic matter, so mix in a 2-3” (5-8cm) layer of good garden compost or composted manure when you prepare the bed.Growing cabbage pulls a lot of nitrogen from the soil, so build organic fertilizers into the soil when you plant. Cabbage thrives in a pH range of 6.5-7
