Farming method
Sow directly outdoors once the soil has warmed up and all risk of frost has passed. Germination is optimal when the soil temperature is between 5 and 27°C . Prepare loose, rich, and well-drained soil, then sow the seeds approximately 1.3 cm deep in rows spaced 30 cm apart. Water gently after sowing and keep the soil evenly moist , but not waterlogged, throughout germination, which usually occurs in 7 to 10 days . Once the seedlings are well established, thin them as needed to encourage good growth. Sow successive batches every 3 weeks from spring until mid- to late summer to ensure a continuous harvest. Lettuce prefers full sun to partial shade and regular watering of approximately 5 cm of water per week .
Harvesting and preservation
Harvesting typically begins about 45 days after sowing . Harvest the outer leaves as needed, or cut the entire plant when it is well-developed. The leaves are best young, fresh, and crisp . Store in the refrigerator in an airtight container to maintain freshness.
Usage ideas
Fresh and crisp salads. Sandwich and wrap filling. Fast growing in containers. Successive harvests throughout the season. Family and urban gardens.
