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

"No matter what I am at Bath for, there are always helpful employees to help me find what I need or tips on how to care for indoor or outdoor plants. They also carry pots, trellises, soil, and interesting plants of all kinds! I was also pleasantly surprised to find compost worms available for purchase without a special preorder. Thank you for being awesome!"

"What a fun and whimsical nursery. There is something for everyone. It feels like every turn you find another treasure. Pricing is boutique-like but plenty of items on the under $15 side. We went in today for greeting cards and found the perfect cards for my grandma. I've purchased many garden supplies and plants here as well. They always have great quality and variety. The owner is amazing, generous, and community focused."
