Prof. Samuel Fitzgerald, Ph.D.If you're short on space, growing cabbage in containers allows more flexibility! If you have the right technique, you can harvest container-grown cabbage (with good technique) just as you would from bed-grown cabbage. A key is to find compact varieties and have consistent care. You can successfully grow cabbage and harvest it fresh from your patio, balcony, or tiny urban garden.
Container Specifications
- Minimum 5-gallon capacity per plant
- Must have drainage holes to prevent waterlogging
- Dark colors absorb heat requiring more frequent watering
- Rotate containers weekly for balanced sun exposure
Soil Requirements
- Use lightweight potting mix with perlite
- Maintain pH between 6.0-7.0
- Enrich with compost for nutrients
- Avoid heavy garden soil that compacts
Water Management
- Water when top inch of soil dries
- Use drip irrigation for consistency
- Mulch surface to retain moisture
- Avoid wetting leaves to prevent disease
Arrange pots according to sun exposure. Cabbage requires full sun (6-8 hours of sunlight per day). Ideal is south-facing. Planters with wheels can follow the sun. In temperature extremes, insulate containers with bubble wrap or burlap.
Establish consistent fertilization schedules. Alternate between a balanced fertilizer and bone meal every 2 to 3 weeks. Use liquid fish emulsion at planting, then switch to a high-potassium fertilizer near the time of head formation. Container plants generally need more frequent feeding than in-ground crops.
Keep a keen eye on pests. While container gardening reduces pests that come from the ground, it will bring in aphids and caterpillars. Check the undersides of the leaves each day. Use neem oil to act preventatively, preferably once a week. Consider ladybugs as a control. Physical barriers, such as netting, are also very effective.
Harvest when heads feel solid. Cut stalks with sanitized shears. Container plants will produce smaller heads, but they will make many more. After harvesting the main heads of some varieties, a second regrowth of smaller heads can occur with proper care. Eat the cabbage as soon as possible after harvesting, within hours, for the freshest flavor.
