Starting Kale Indoors
In areas like Birmingham (Zone 7b), start kale seeds indoors from January 15 to February 15. This timing allows seedlings to be ready for outdoor transplanting from mid-February to mid-March, before the heat of summer sets in.
Transplanting Kale Seedlings
Transplant seedlings outdoors from February 15 to March 15, ensuring soil temperatures are consistently above 45°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. Alabama’s warm climate can cause soil to dry out quickly, making regular watering essential.
- 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 soil structure.
Pest and Disease Management:
- Monitor for common pests like aphids, cabbage worms, and flea beetles. 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 harvesting season, particularly in Alabama’s long growing season.
