How to Plant Cabbage Seeds

1. Indoor Planting
   • Use seed trays or pots filled with seed-starting mix.
   • Sow seeds 1/4 inch deep and keep the soil moist.
2. Direct Sowing
   • Plant seeds 1/4–1/2 inch deep in rows spaced 18–24 inches apart.
3. Transplanting
   • Move seedlings outdoors when they’re 4–6 weeks old and have 4–5 true leaves.
4. Spacing
   • Space plants 12–24 inches apart, depending on the variety, to allow room for growth.

Caring for Cabbage Seedlings

1. Watering
   • Keep the soil consistently moist but avoid overwatering to prevent root rot.
2. Fertilizing

3. Thinning
   • Thin seedlings to the recommended spacing once they’ve developed their first set of true leaves.
4. Weed Control
   • Remove weeds regularly to reduce competition for nutrients.

Common Pests and Diseases

Pests

   • Use a sharp knife to cut the head at the base, leaving outer leaves and roots intact for potential regrowth.
3. Storage
   • Store cabbage in a cool, dark place for up to 2 weeks or refrigerate for up to a month.

Tips for Success with Cabbage Seeds

1. Practice Crop Rotation
   • Avoid planting cabbage in the same spot as other brassicas to prevent soil-borne diseases.
2. Use Companion Plants
   • Grow cabbage alongside marigolds, onions, or dill to deter pests.
3. Mulch Your Plants
