~ Sowing ~
When to Start Inside: 4-6 weeks before your average last frost date.
When to Start Outside: Sow seeds directly in the garden as soon as the soil can be worked in early spring or late summer for a fall crop. For continuous harvest, sow seeds every 2-3 weeks.
Planting Depth: Sow seeds ¼ inch deep.
Watering: Keep the soil consistently moist but not waterlogged.
Light and Temperature: Lettuce prefers cooler temperatures between 60-70°F (15-21°C). It can tolerate some shade, especially in warmer climates, to prevent bolting.
Germination: Seeds typically germinate in 7-10 days.
~ Transplanting Seedlings Outdoors ~
Timing: Transplant seedlings outdoors when they have 4-6 true leaves and after the risk of frost has passed.
Location: Choose a sunny location with well-drained soil. In warmer climates, partial shade can help prevent bolting.
Spacing: Space plants 6-8 inches apart to allow for adequate growth and air circulation.
Transplanting: Gently transplant seedlings into the prepared soil, ensuring the root ball is covered and the plant is stable. Water well after planting.
~ Growing ~
Watering: Water regularly to keep the soil evenly moist. Mulching can help retain soil moisture and keep roots cool.
Fertilizing: Lettuce benefits from a balanced fertilizer or compost worked into the soil before planting. A light side-dressing of compost or fertilizer can be applied every few weeks during the growing season.
Pest and Disease Management: Monitor for pests such as aphids, slugs, and snails. Use organic pest control methods such as insecticidal soap or diatomaceous earth. Ensure good air circulation to prevent fungal diseases.
Maintenance: Harvest leaves as needed by cutting them off at the base of the plant. This will encourage new growth and extend the harvest period.
~ Harvesting ~
When to Harvest: Black Seeded Simpson Lettuce can be harvested when the leaves are full-sized but still tender, typically 40-50 days after sowing.
How to Harvest: Pick outer leaves as needed, or cut the entire rosette at the base. For baby greens, harvest when the leaves are young and tender.
Drying and Storing: Lettuce is best used fresh. For short-term storage, keep harvested leaves in the refrigerator in a plastic bag or container.
~ Seed Saving ~
Allow one or two plants to bolt and produce seeds. Once the flower heads have dried, collect the seeds and store them in a cool, dry place for future planting.
