Read labels carefully. All kales and cabbages are edible, but some varieties are grown more for their color than for their flavor or tenderness.
Check your nursery for seedlings in late summer and early fall. Or, start from seeds in midsummer in the North and late summer in the South.
Sow seeds in a corner of the vegetable garden. Plant 1/2-inch deep and 3 inches apart. Then transplant to their final place elsewhere in the garden.
Plant seedlings or mature plants in average, well-drained soil, spaced 10 to 12 inches apart.
Keep soil moist.
Trim fading or diseased leaves as needed.
Pull up and discard plants in early winter once they've faded and withered.
