Starting Kale Indoors

In areas like Atlanta (Zone 7b), start kale seeds indoors from August 1 to September 15. This timing ensures that seedlings are ready for outdoor transplanting from mid-September to mid-October, as temperatures cool and become ideal for kale growth.

Transplanting Kale Seedlings

Transplant seedlings outdoors from September 15 to October 15, ensuring soil temperatures are consistently below 85°F. Space seedlings 12-18 inches apart in rows at least 18 inches apart to allow for good air circulation and sunlight exposure.

General Care and Maintenance

Watering:

  • Water deeply and consistently to keep the soil evenly moist. Georgia’s warm climate can cause soil to dry out quickly, so regular watering is essential, especially during dry spells.
  • Water at the base of the plants to prevent wetting the foliage, which helps reduce the risk of fungal diseases.

Fertilizing:

  • Apply a balanced fertilizer at planting and again when the leaves begin to develop. Adding compost to the soil before planting can improve fertility and moisture retention.

Pest and Disease Management:

  • Monitor for common pests like aphids, flea beetles, and cabbage worms. The humid climate can also encourage fungal diseases, so vigilance is necessary.
  • Use organic or integrated pest management strategies to protect your plants from pests and diseases.

Harvesting Kale:

  • Harvest kale leaves when they are large enough to eat but still tender. Regular harvesting encourages new growth and can extend the season, particularly in Georgia’s mild winter conditions.
