When to Grow

This kale variety is a cool-season crop. You can sow seeds directly outdoors or transplant them 2-4 weeks before the last expected frost date in spring, or 8 weeks before fall frost dates. Dwarf Siberian kale can withstand temperatures as low as 20 F and can continue growing into winter in milder climates​. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Sow seeds about 1/4 inch deep, spacing them 2-4 inches apart. Thin seedlings to about 8 inches apart once they are a few inches tall to give the plants enough room to grow. If starting seeds indoors, use seed trays with a well-draining seed-starting mix and keep them in a warm, well-lit area​.

How to Grow

Water Dwarf Siberian kale often to keep the soil evenly moist but not waterlogged, which helps prevent the leaves from becoming bitter. Use mulch to retain moisture and regulate soil temperature. Apply a balanced, organic fertilizer or compost every 4-6 weeks during the growing season. This kale is relatively resistant to pests and diseases but keep an eye out for aphids and cabbage worms, and manage them using organic methods like neem oil or beneficial insects.

How to Save Seeds

  • Like all cabbage family members, kale is biennial.
  • Kale is insect pollinated and will cross with some closely related cabbage family members, so it is wise to isolate varieties at least a mile apart to ensure pure seed. Other techniques such as alternate day caging can be used if isolation is not possible.
  • You will need to overwinter plants to harvest seeds. Mulch plants heavily with straw or cover with row cover and greenhouse plastic in an attempt to nurse plants through the winter. You can also dig up plants and store them inside to replant in spring.
  • When the flower spikes emerge in the second year, let the seed pods dry to brown and cut off the entire flower spike.
  • Hang flower stalks upside down indoors over a tarp, allowing the seeds to drop onto the tarp.
  • Seeds will remain viable for up to 4 years.
