Starting your own vegetable transplants can be a rewarding experience, especially when it comes to cabbage. For gardeners in Zone 1, timing is crucial to ensure a healthy and productive crop. March is an ideal month to begin cabbage seeds indoors, giving them enough time to mature before transplanting outdoors.
Why Grow Cabbage Transplants?
Growing your own transplants offers several advantages. It allows you to choose high-quality seeds, control the growing environment, and get a head start on the growing season. Cabbage is a cool-season crop that thrives when started early, making March the perfect time in Zone 1 to begin.
Choosing the Right Cabbage Seeds
Select varieties suited for your climate and season length. Popular options include:
- Early Jersey Wakefield
- Savoy
- Green Globe
- Red Acre
Check seed packets for specific planting instructions and days to maturity to plan your growing schedule accordingly.
Starting Cabbage Seeds Indoors
Use seed-starting trays or small pots filled with a quality seed-starting mix. Sow seeds about ¼ inch deep and keep the soil consistently moist. Maintain indoor temperatures around 65-75°F (18-24°C) for optimal germination.
Lighting and Temperature
Provide ample light using grow lights or a sunny windowsill. Cabbage seedlings need at least 12-16 hours of light daily. Keep the temperature steady to prevent leggy seedlings and promote strong growth.
Care and Maintenance
Water seedlings regularly to keep the soil moist but not waterlogged. Thin out weaker seedlings once they develop their first true leaves, leaving the strongest plants to grow.
Fertilizing
Feed your seedlings with a diluted liquid fertilizer every couple of weeks to promote healthy growth and prepare them for transplanting.
Transplanting Outdoors
In Zone 1, aim to transplant your cabbage seedlings outdoors after the last frost date, typically in late May or early June. Harden off seedlings by gradually exposing them to outdoor conditions over a week.
Choose a sunny location with well-draining soil. Space plants about 12-18 inches apart to allow for growth. Water thoroughly after transplanting and mulch to retain moisture and suppress weeds.
Additional Tips for Success
- Keep a gardening journal to track planting dates and growth progress.
- Use row covers to protect young plants from pests and late frosts.
- Regularly check for pests like cabbage worms and aphids, and manage them promptly.
By starting your cabbage seeds in March, you set the stage for a successful growing season. With proper care and timing, you can enjoy fresh, homegrown cabbage right from your garden.
