Growing vegetables in containers is a great alternative to planting them in beds in the ground. Whether you’re short on space, have poor soil, or can’t or don’t want to bed all the way down to the ground, containers can be just the thing you need. Keep reading to learn how to grow cabbage in containers.
Growing Cabbage in Pots
Can you grow cabbage in a pot? Of course, you can! Growing cabbage in containers is easy, as long as you don’t crowd them. Cabbage plants can get huge, growing as high as 4 feet (1.2 m) and nearly as wide. Limit your plants to one per 5-gallon (19 L.) container. Your container-grown cabbage will still grow planted closer together, but the heads will be noticeably smaller.
Cabbage grows best when the daytime temperature is around 60 F. (15 C.) and, in most places, it can be grown as both a spring and fall crop. Start your seeds indoors 4 weeks before your last frost date in spring or 6-8 weeks before your first frost date in autumn. Transplant your seedlings into your large outdoor containers when they’re about a month old.
Care for Cabbages in Pots
Cabbage container care can be tricky. Cabbage needs steady, frequent watering to encourage healthy growth. Don’t overwater, though, or the heads may split! Give your plants a good drink 2 to 3 times a week.
Pests can be a real problem with cabbage, and while growing cabbage in containers gives you the great advantage of being able to use fresh, uncontaminated soil, even container-grown cabbage isn’t completely safe.
Put fabric around your young plants to prevent cabbage worms and cabbage root maggots from laying their eggs in the soil. Wrap the base of your plants’ stalks with cardboard or tin foil to thwart cutworms.
If your container-grown cabbage gets infected in any way, discard the soil at the end of the season. Don’t reuse it!
