Collard and mustard greens are a part of the cabbage family. These greens are popular in the South and grow very well in hot weather, but gardeners in central and northern parts of the U.S. can also grow them successfully. Collard and mustard greens grow thick, dark green leaves, and have a spinach flavor.
Collards and mustard greens like sunlight, so plant in an area where the sun will shine on the plants daily. Plant seeds directly into the ground, early in the spring. You can plant again in midsummer for a second, fall harvest.
Plant seeds approximately 1/2 inch deep and space them 6 inches apart, in rows 3 feet apart.
Fertilize and keep soil well watered during periods of drought.
Pick the leaves as soon as they are large enough. Younger leaves are more tender and succulent. Discard leaves showing signs of browning or yellowing.
