Cabbage is an easy crop and can be started from seed, indoors. The most important thing to remember is to set your transplants into the garden four wees before the last frost. This way they have time to mature before summer’s heat sets in.
Cabbage needs a soil pH of 6.5 to 6.8 so either test the soil yourself of have the county extension office conduct a test for you. Get recommendations on what to use to amend the soil to bring it to the correct pH.
After you’ve dug up the garden bed, add 3 inches of composted manure and the amendments suggested by the soil analysis. Mix them into the top 6 inches of soil.
When you plant the cabbage starts, they should be set deep enough so that half the stem is buried. Space them 12 to 24 inches apart, unless you are growing the O-S Cross hybrid. Those giants need a minimum of 36 inches of space between them.
Make sure your cabbage plants get an inch to an inch and a half of water a week, either from rain or manual irrigation. When new leaves first appear after transplanting, give the plants a shot of 20-20-20 fertilizer, at the rate suggested on the package.
