Planting Asian Greens
When to Plant:
- For fall and winter harvests, sow seeds from September to November.
- For early spring harvests, sow seeds in January or February.
- Succession planting every 2-3 weeks ensures a continuous supply of fresh greens.
How to Plant:
- Direct Sowing:
- Sow seeds ¼ inch deep and 2-4 inches apart in rows spaced 12 inches apart.
- Thin seedlings to 6-8 inches apart for larger varieties like bok choy or komatsuna.
- Indoor Starting Option:
- Start seeds indoors 3-4 weeks before transplanting. Use seed trays with pre-moistened seed-starting mix and keep them under grow lights.
- Transplant when seedlings have 2-3 true leaves, spacing them 6-12 inches apart depending on the variety.
- Container Planting:
- Asian greens grow well in containers at least 6-8 inches deep. This is perfect for suburban gardeners with limited space.
Caring for Asian Greens
Asian greens grow quickly with minimal care, but a few key practices will ensure healthy, flavorful harvests.
Watering: Water consistently to keep the soil evenly moist. Dry conditions can lead to bolting, while overly wet soil may cause root rot. A drip irrigation system can help maintain consistent moisture levels.
Fertilizing: Feed Asian greens with a balanced organic fertilizer every 3-4 weeks to encourage steady growth. Avoid excessive nitrogen, which can cause weak, overly leafy plants prone to pests.
Mulching and Weeding: Apply a thin layer of organic mulch around plants to retain moisture and suppress weeds. Hand-pull any weeds that appear to avoid competition for nutrients.
Common Pests and Diseases
Asian greens are relatively pest-resistant but may occasionally attract some common garden pests:
- Flea Beetles: These pests create tiny holes in leaves. Protect young plants with floating row covers and keep the area weed-free.
- Aphids: Wash off with a strong spray of water or apply insecticidal soap.
- Slugs and Snails: Remove these pests by hand or use organic slug bait around plants.
- Clubroot: This fungal disease affects brassicas, including Asian greens. Rotate crops annually and maintain slightly acidic soil to reduce risk.
Harvesting and Using Asian Greens
When to Harvest:
- Most Asian greens are ready for harvest within 30-50 days of planting, depending on the variety.
- Harvest baby greens when they’re 3-4 inches tall for tender salads or let them mature for heartier dishes.
How to Harvest:
- Use scissors or a sharp knife to cut outer leaves first for a cut-and-come-again method, or harvest the entire plant by cutting it at the base.
- Regular harvesting encourages new growth and prolongs the harvest season.
Storing Asian Greens:
- Store harvested greens in the refrigerator in a damp paper towel or a perforated plastic bag. Use them within a week for the best flavor and texture.
Companion Planting with Asian Greens
Pair Asian greens with these plants for better growth and pest control:
- Good Companions: Radishes, carrots, scallions, and lettuce. These crops share similar growing conditions and make efficient use of garden space.
- Avoid Planting With: Other brassicas like broccoli or cabbage, as they attract the same pests.
