2. When to Plant
In Charlotte, you can plant kale in both spring and fall:
- Spring Planting: Sow seeds indoors 6-8 weeks before the last frost (early March) and transplant outdoors in late March or early April.
- Fall Planting: Direct sow seeds or transplant seedlings in late August to early September for a fall and winter harvest.
3. Where to Plant
- Sunlight: Kale grows best in full sun (6-8 hours daily) but tolerates partial shade, especially during hot weather.
- Soil: Use well-draining soil enriched with compost or organic matter. Aim for a pH of 6.0-7.5.
Caring for Kale
1. Watering
- Kale requires consistent moisture but doesn’t like soggy soil.
- Water deeply 1-2 times per week, ensuring the soil remains moist but not waterlogged.
2. Fertilizing
- Kale is a heavy feeder, so prepare the soil with a nitrogen-rich fertilizer or compost before planting.
- Side-dress with compost or an organic fertilizer every 4-6 weeks during the growing season.
3. Mulching
- Apply a layer of mulch (straw, pine needles, or shredded leaves) to retain soil moisture, regulate temperature, and suppress weeds.
4. Temperature Management
- Kale thrives in temperatures between 55-75°F.
- Use shade cloth during Charlotte’s hotter days in late spring or summer to prevent bolting.
Pest and Disease Management
1. Common Pests
- Cabbage Worms and Loopers: Hand-pick these pests or use organic treatments like Bt (Bacillus thuringiensis).
- Aphids: Spray with insecticidal soap or a strong jet of water to dislodge them.
- Flea Beetles: Protect seedlings with floating row covers.
2. Diseases
- Powdery Mildew: Prevent by ensuring good airflow and avoiding overhead watering.
- Clubroot: Rotate crops annually and avoid planting kale in the same spot as other brassicas.
Harvesting Kale
1. When to Harvest
- Kale is ready to harvest 50-70 days after planting or when the leaves are about the size of your hand.
- Harvest the outer leaves first, leaving the central bud to continue producing new growth.
2. How to Harvest
- Use scissors or a sharp knife to cut leaves off close to the stem.
- Regular harvesting encourages continuous growth and prevents the plant from bolting.
Growing Kale in Containers
If space is limited, kale grows well in containers:
- Use a pot at least 12 inches wide and deep.
- Ensure the container has drainage holes and fill it with nutrient-rich potting soil.
Companion Planting for Kale
Kale grows well with:
- Herbs: Dill and cilantro deter pests.
-
Vegetables: Onions, garlic, and beets make great companions.
Avoid planting kale near other brassicas like cabbage and broccoli to reduce pest pressure.
