Starting Kale Indoors
In areas like New York City (Zone 7b), start kale seeds indoors from March 15 to April 15. This timing ensures that seedlings are ready for outdoor transplanting from mid-April to mid-May, after the last frost.
Transplanting Kale Seedlings
Transplant seedlings outdoors from April 15 to May 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. New York’s warm summers can dry out the soil quickly, 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 soil structure.
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 extends the harvesting season, particularly in New York’s varied growing conditions.
