Starting Kale Indoors
In areas like Honolulu, kale seeds can be started indoors at any time of the year. This flexibility allows for continuous planting and harvesting cycles, with indoor starting recommended during particularly hot or dry periods.
Transplanting Kale Seedlings
Transplant seedlings outdoors year-round, ensuring soil temperatures are consistently suitable for growth. 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. Hawaii’s tropical climate may require frequent watering, especially in dry areas.
- 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 improves fertility and moisture retention.
Pest and Disease Management:
- Monitor for common pests like aphids, flea beetles, and cabbage worms. Hawaii’s tropical 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 provide a continuous supply of fresh kale year-round in Hawaii’s favorable climate.
