How To Grow

  1. Container Selection: Choose a container with a depth of at least 8-12 inches and a diameter of 12-18 inches. Ensure the container has drainage holes to prevent waterlogging.
  2. Soil: Fill the container with well-draining potting mix enriched with compost or aged manure to provide nutrients.
  3. Variety Selection: Select kale varieties suited for container growing, such as ‘Dwarf Blue Curled’ or ‘Red Russian.’
  4. Location: Place the container in a location with full sun to partial shade. Kale can tolerate cooler temperatures and even benefits from some frost.
  5. Planting: Sow kale seeds directly into the container or transplant seedlings, spacing them about 12-18 inches apart.
  6. Watering: Keep the soil consistently moist but not waterlogged. Water kale regularly, especially during dry spells, to promote healthy growth and prevent bitterness.
  7. Mulching: Apply a layer of mulch around the base of the kale plants to retain moisture, regulate soil temperature, and suppress weeds.
  8. Fertilizing: Kale is a moderate feeder and benefits from occasional fertilization. Apply a balanced liquid fertilizer or compost tea every 3-4 weeks.
  9. Harvesting: Harvest kale leaves when they reach the desired size, typically 6-10 inches long. Use scissors to cut outer leaves, allowing the inner leaves to continue growing for future harvests.
  10. Succession Planting: To extend your harvest, sow seeds or transplant new seedlings every 2-3 weeks throughout the growing season.
