Ornamental cabbage can be planted anywhere in the landscape. It is best planted where it will receive full to the partial sun during the day. Ornamental cabbage should not be planted too early since cold temperatures or lack of sunlight may cause the plant to become spindly and weak during the growing season.
Planting ornamental cabbage can be done in many ways. Seeds can be started indoors six to eight weeks before they are transplanted in the garden. On average, plants that are grown from seed will take three to four weeks before they can mature into plants that can survive in temperatures colder than 40 degrees Fahrenheit. Transplanting starts in the spring when nighttime temperatures stay above 25 degrees Fahrenheit. Seeds can be planted in the garden where they are to mature once nighttime temperatures reach 55 degrees Fahrenheit. Once plants have reached a height of one foot, you should prune the tops of them down by four to six inches or their remaining growth after harvesting will become spindly.
Ornamental cabbage is not susceptible to many pests. If you discover that the plant has clubroot, treat it by soaking the plants in a solution of baking soda and water for two hours. To protect against snails and slugs, spread wood ashes or diatomaceous earth around the plants.
Ornamental cabbage is susceptible to black rot particularly when it is watered from overhead as this encourages the spread of the fungus. If your ornamental cabbage becomes infected with black rot, remove any diseased leaves and destroy them. Ensure that you do not plant ornamental cabbage in an area where it has previously grown since this disease is very persistent. Spraying hydrogen peroxide on the foliage may help reduce any damage done by black rot if it is caught early enough.
You should mulch the area where ornamental cabbage has grown to reduce weed growth and retain moisture. It is best to fertilize after flowering has ended because this will help promote fall regrowth during the growing season. Do not over-fertilize since too much nitrogen may cause your plants to become weak and spindly.
You may also propagate ornamental cabbage through division in the spring or fall. Ornamental cabbage can be transplanted to different locations in the garden following the end of its growing season, although you should allow at least ten weeks for them to become acclimated.
