How to Grow Cabbage in Containers

Place about 1 inch of gravel in the bottom of a planting container to facilitate drainage. Fill the container about three-quarters full of potting soil.

Remove the cabbage plant from its temporary container and place it in the center of the container so the crown of the plant is about 1 inch below the rim of the container. Check the depth to make sure you place the cabbage plant at the same depth as it was in the temporary container. Fill additional potting soil in and around the cabbage plant and firm up the soil gently with your hands.

Water the cabbage plant thoroughly to saturate the soil. Place the container in a location that receives full and direct sunlight -- at least six hours each day.

Keep the potting soil evenly moist by watering the cabbage plant every day or every other day.

Fertilize the cabbage plant every other week by mixing 10-3-3 fertilizer with water according to the package recommendations. Pour the fertilizer over the soil carefully without splashing the foliage with fertilizer.

Decrease the watering frequency slightly, when the cabbage develops a head, to prevent the head from splitting from too much moisture.

Harvest the cabbage when the head feels firm and the base of the cabbage head is at least 4 inches in diameter. Slice the head cleanly off of the plant base, leaving the outer leaves still attached. Check back about four weeks later to see if smaller heads are growing from the severed stem.
