Cabbages come in many different types and, with a bit of planning, it can be possible to harvest cabbages year-round. Summer cabbages come in different colors and sizes and these types, as the name suggests, are ready to harvest come summer.
I grew a lot of cabbages as a professional kitchen gardener, and it was beneficial to grow many different types to have a long harvesting season. This included both green and red summer cabbages that I always grew from seed and were harvested to either be sold to the public or used by chefs.
