Starting Kale Indoors
In areas like Houston (Zone 9a), start kale seeds indoors from January 15 to February 15. This ensures seedlings are ready for transplanting outdoors 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. Texas’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 before planting helps improve soil fertility and structure.
Pest and Disease Management:
- Watch out for common pests like aphids, flea beetles, and cabbage worms. Texas’s warm, 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 promotes new growth and can extend the harvesting season, especially in Texas’s mild winter and spring conditions.
