Starting Kale Indoors
In areas like Columbia (Zone 8a), start kale seeds indoors from January 15 to February 15. This ensures seedlings are ready for outdoor transplanting from mid-February to mid-March, before the heat of summer arrives.
Transplanting Kale Seedlings
Transplant seedlings outdoors from February 15 to March 15, ensuring soil temperatures are consistently above 45°F. Space plants 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 maintain evenly moist soil. South Carolina’s warm climate can dry out the soil quickly, so regular watering is essential.
- Water at the base of the plants to keep the foliage dry and reduce the risk of 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:
- Watch for common pests like aphids, flea beetles, and cabbage worms. South Carolina’s humid climate can also encourage fungal diseases, so regular monitoring is important.
- Use organic or integrated pest management practices to keep your kale plants healthy.
Harvesting Kale:
- Pick the leaves when they’re large enough to eat but still tender. Regular harvesting encourages new growth and extends the harvesting season, especially in South Carolina’s mild winter and spring conditions.
