Cabbage has been a staple vegetable for bout ten thousand years. It originated as a weedy sea kale found in the Mediterranean, and was gradually domesticated into its current shape.

There are all sorts of ways to use cabbage – raw and shredded  into a crispy slaw, blanched and rolled into cabbage rolls, or added to soups and stews. For a longer shelf life, you can ferment it into sauerkraut or kimchi.

Getting Started: How to Grow Cabbage From Seeds

Cabbage seeds will germinate in less than a week, so there is no need to start with seedlings. Plant the seeds indoors in April, and in about a month they are ready for your outdoor containers.

Choose the type of cabbage you want to plant – regular green, red, Savoy or Chinese. There are also mini varieties that grow to about the size of a softball, perfect for a container garden.

Many people plant container gardens because of space, but there also those who just love miniatures – anything mini. Just about every vegetable comes in a mini version that these types of people absolutely adore.

Select a container that is fairly deep. Cabbage roots need at least one foot of soil to grow. Deep window boxes or half barrels are excellent choices. Just make sure there are adequate drainage holes at the bottom.

Fill your container with a mixture of potting soil and compost. You can plant extra seeds, in case some don't take, and thin out your crop later, or plant seedlings.

How to grow cabbage? Avoid full shade. Place your containers where the plants will get part shade to full sun. Always keep the soil moist, but not soggy.

Water and Fertilizer For Container Garden Cabbages

All vegetables need plenty of water. This is very important for container grown vegetables because containers don't hold moisture as well as ground gardens.

If you forget to water, and the soil dries out, you may be tempted to over water to get the moisture level up. This causes stress on the cabbage and the heads may split. Split heads don't taste nearly as good.

Also feed the plants about once a week with water-soluble vegetable fertilizer containing boron, calcium and magnesium, or an organic fertilizer such as fish emulsion or compost extracts.
