Soil Type: Prefers rich, well-drained soil with a pH of 6.0–7.5. Adding compost improves soil fertility.
When to Plant: Sow seeds directly outdoors in early spring or late summer for a fall crop. For an earlier harvest, start seeds indoors 4–6 weeks before the last frost.
Direct Sowing: Plant seeds 1/2 inch deep, spacing them 6–12 inches apart in rows 18–24 inches apart. Thin seedlings to the desired spacing as they grow.
Indoor Sowing: Start seeds in trays and transplant when seedlings are 4–6 inches tall.
Succession Planting: Sow every 2–3 weeks for a continuous harvest during the growing season.
Watering: Water consistently to keep the soil evenly moist but not soggy. Mulch around plants to retain moisture and regulate temperature.
Fertilizing: Use a balanced fertilizer or compost at planting and mid-season to promote vigorous leafy growth.
Pruning: Harvest outer leaves regularly to encourage new growth and maintain plant health.
Pest and Disease Control: Monitor for aphids, slugs, and leaf miners. Use organic pest control methods and ensure proper spacing for airflow.
When to Harvest: Harvest outer leaves when they are 8–10 inches long, typically 50–60 days after planting. Baby greens can be harvested earlier.
How to Harvest: Use scissors or a knife to cut leaves at the base, leaving the central growing point intact for continuous harvests.
Seed Collection: Allow plants to bolt and form seed heads. Collect seeds once heads are fully dry.
Storing Seeds: Store seeds in an airtight container in a cool, dry place.
