In 10–12 weeks after planting, your cabbage will be ready to pick. (The growing season will be longer if planted in the Fall in the far Southern states.) You can harvest your cabbage anytime after the head has formed.
Sometimes the cabbage head looks ready but isn’t. Squeeze the head to see. Does it feel loose on the inside? If so, leave the cabbage to grow a little more.
When you squeeze the cabbage head and it feels solid and firm, it’s ready. Ask an adult to cut the cabbage head off for you.
Don’t leave the cabbage head too long in the garden after it’s ready. The head could crack or split. If this happens, harvest the head immediately.
When harvesting, remember to take a photo with your cabbage and to measure and weigh it! You’ll need this info to submit your cabbage for your state winner.
