Starting Kale Indoors
In areas like Jacksonville (Zone 9a), start kale seeds indoors from September 1 to October 15. This timing ensures that seedlings are ready for outdoor transplanting from mid-October to early December, when the weather is cool and ideal for kale growth.
Transplanting Kale Seedlings
Transplant seedlings outdoors from October 15 to December 1, 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. Florida’s warm climate can cause soil to dry out quickly, especially in the sandy soils common in some areas, so regular watering is 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 moisture retention, particularly in sandy soils.
Pest and Disease Management:
- Monitor for common pests like aphids, flea beetles, and cabbage worms. Florida’s 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, especially in Florida’s mild winter conditions.
