- Soil requirements: Lactuca sativa, commonly known as lettuce, prefers well-drained, fertile soil with a pH level between 6.0 and 6.8. The soil should be rich in organic matter to support healthy growth.
- Sunlight needs: Lettuce requires full sun to partial shade. Ideally, it should receive at least 6 hours of sunlight per day, but it can tolerate some shade, especially in warmer climates.
- Watering requirements: Lettuce needs consistent moisture to thrive. Water the plants regularly, ensuring the soil remains evenly moist but not waterlogged. It's best to water in the morning to allow the foliage to dry before evening, reducing the risk of disease.
- Planting season: The best time to plant lettuce seeds is in early spring or late summer. Lettuce prefers cooler temperatures, so avoid planting during the peak of summer heat.
- Depth and spacing: Plant lettuce seeds at a depth of 1/4 to 1/2 inch. Space the seeds about 1 inch apart, and thin the seedlings to 6-12 inches apart, depending on the variety, to allow adequate room for growth.
- Germination time: Lettuce seeds typically germinate within 7 to 14 days after planting, depending on the soil temperature and conditions.
- Maturity time: Lettuce generally reaches maturity within 45 to 55 days after planting, though this can vary depending on the variety.
- Harvesting time: The best time to harvest lettuce is in the early morning when the leaves are crisp and full of moisture. Avoid harvesting during the heat of the day to prevent wilting.
- Harvesting tips: Use a sharp knife or scissors to cut the leaves or heads of lettuce. For leaf varieties, you can harvest the outer leaves as needed, allowing the inner leaves to continue growing. Store harvested lettuce in a cool, moist environment to maintain freshness. Avoid washing the leaves until you're ready to use them to prevent spoilage.
