Botanical Interests One Kilo Slow Bolt Napa Cabbage Seeds
Also called napa cabbage, 'One Kilo Slow Bolt' has a delicate flavor, a soft texture in between that of lettuce and regular cabbage, and tight heads have a creamy yellow interior. Grows with ease in fall, and can be sown in spring if care is taken to protect young plants from temperatures of 50°F or below, which may cause plants to bolt. Grows best at 60°-65°F.
Sowing Information:
- Light: Full sun
- When to Start Inside: 4 to 6 weeks before your average last frost date transplanting after your average last frost date, and 4 to 6 weeks before transplanting outdoors in summer for a fall crop. Sow in biodegradable pots to avoid root disturbance. Mild Climates: Sow in fall for a cool-season harvest.
- When to Sow Outside: RECOMMENDED. 2 to 4 weeks before your average last frost date for a summer crop or 8 to 10 weeks before your average first fall frost date for a fall crop. Ideal soil temperature for germination is 75°-85°F. Persistent temperatures of 50°F or below while plants are young can cause bolting (premature flowering), cover as necessary.
- Seed Depth: Plant seeds ¼ inch deep
- Seed Spacing: A group of 3 seeds every 18-24 inches
- Row Spacing: 24-36 inches
- Thinning: When 3" tall, thin to 1 every 18-24 inches
- Days to Germinate: 7-12 days
- Days to Maturity: 50-55 days
Growing Notes:
- Harvesting: Harvest heads when they are well developed, firm, and solid when squeezed. Cut off heads at base with a sharp knife. Cabbages left in the ground beyond maturity are more subject to disease and splitting. Harvest in the morning if possible. If harvested in the heat, dunk in ice water to reduce "field heat" and increase storage time. Allow to drain before storing.
- Attributes: Good for containers

"They have so much fun stuff to look at even if you're not buying plants! They also have a cool deal where, if you buy the container and the plant, they'll plant it for you. There's clothes, kitchen stuff, kids stuff, books, nick snacks, etc. My mom and I go in just to hang out and look at stuff sometimes, but last time, I got this plant. It went from beautiful to MAMMOTH and beautiful. We named her Victoria."
