Collards is actually a tall growing form of kale and cabbage seedlings used for greens are sometimes called collards. It takes about 75 days for the plants to mature. A well drained soil with a good supply of organic matter is best. Planting is done outdoors in early April but the plants may be started early indoors. It takes 4 to 6 weeks to get a suitable transplant. The seed is planted 1/2 inch deep or plants are set 6 to 8 inches apart. If no other fertilizer was used, apply 3 to 4 pounds of 12-12-12 per 100 foot of row. Later in the season, sidedress with nitrogen to assure fast growth.
Harvest greens as they are wanted or produced. They are not stored.
