2. Starting your Seeds
One of the great things about growing cabbage is that you can start the seeds quite early. You will want to start growing your cabbage seeds about a month before the last frost of the spring.
If you do not want to start your seeds indoors you should plant your cabbage seeds during the spring as soon as you can turn the soil. The weather can still be cool as the cabbage seeds can withstand cooler weather. You can place your seedlings in the garden as soon as they are about three inches tall.
The plants can be transplanted into the ground up to a month before the last spring frost. If you live in a cool summer region you should plant your cabbage later in the spring in order to harvest it in the fall. If you live in an area that has a milder winter you can start your seeds in the late summer for a spring harvest.
