How to Grow Kale

Kale is a nutrient-dense leafy green that is easy to grow and thrives in cooler temperatures. It can be grown in the spring, fall, and even winter in some climates. Follow this guide to learn how to grow healthy kale using organic methods.

What You’ll Need

  • Kale seeds or transplants
  • Well-draining soil
  • Compost
  • Watering can or hose
  • Mulch

Choosing the Right Variety

Kale comes in several varieties. Some popular types include:

  • Curly Kale: Frilly leaves with a robust flavor.
  • Lacinato Kale: Dark, flat leaves with a tender texture.
  • Red Russian Kale: Tender, purple-veined leaves.

Preparing the Soil

Kale prefers well-drained, fertile soil with a pH of 6.0-7.0. Here�s how to prepare your soil:

  1. Loosen the Soil: Till the soil to a depth of 8-10 inches (20-25 cm). Remove any stones or debris.
  2. Add Compost: Mix in 1-2 inches (2.5-5 cm) of compost to improve soil fertility and structure.
  3. Add Organic Matter: Incorporate well-rotted manure or homemade compost for added nutrients.

Planting Seeds or Transplants

Kale can be grown from seeds or transplants. Here�s how:

  1. Starting Indoors: Sow seeds 6-8 weeks before the last frost. Transplant seedlings outdoors after hardening off, spacing them 12-18 inches (30-45 cm) apart.
  2. Direct Sowing: Plant seeds 1/4 inch (0.6 cm) deep in rows spaced 12-18 inches (30-45 cm) apart. Thin seedlings to 12-18 inches (30-45 cm) apart once they have a few true leaves.

Watering and Care

Kale needs consistent watering and care. Follow these tips:

  • Water Regularly: Keep the soil consistently moist, but not waterlogged. Water in the morning to reduce evaporation.
  • Mulch: Apply a layer of mulch around the plants to retain moisture and suppress weeds.


Kale benefits from organic fertilization. Use compost tea or fish emulsion every 2-3 weeks during the growing season.


Kale can be harvested at any stage, depending on your preference. Here�s how:

  • Baby Greens: Harvest young leaves when they are 3-4 inches (7.5-10 cm) tall.
  • Mature Leaves: Pick individual leaves as needed, starting from the outer leaves.

Storing Kale

Kale is best used fresh but can be stored for short periods:

  • In the Fridge: Store kale in a plastic bag in the refrigerator crisper drawer. Use within 1-2 weeks.
  • Freezing: Blanch kale leaves in boiling water for 2-3 minutes, then cool in ice water. Freeze in airtight containers for up to 6 months.

Tips and Tricks

  • Succession Planting: Sow seeds every 2-3 weeks for a continuous supply of fresh kale.
  • Companion Planting: Grow kale with beans, onions, or herbs to maximize garden space.


Growing kale using organic methods will help you achieve a bountiful harvest of healthy, nutrient-dense greens. With proper care and attention, you can enjoy fresh kale from your garden all season long.
