How do I grow lettuce from seed?
Lettuce is a cool-season crop that can be grown in the spring, fall, or winter in most climates. It is a relatively easy vegetable to grow from seed, and it can be a great way to save money on your grocery bill.
To grow lettuce from seed, you will need:
- Lettuce seeds
- Seed starting mix
- Seedling tray
- Grow light (optional)
- Water
- Fertilizer (optional)
- Prepare the seed starting mix. Fill the seedling tray with seed starting mix and moisten it with water.
- Sow the seeds. Sprinkle the lettuce seeds on top of the seed starting mix. Do not cover the seeds with soil, as they need light to germinate.
- Water the seeds. Gently water the seeds with a spray bottle or a watering can with a fine nozzle.
- Place the seedling tray in a warm place. The ideal temperature for germinating lettuce seeds is between 65 and 75 degrees Fahrenheit. You can place the seedling tray on a heat mat or in a warm spot in your house.
- Keep the seeds moist. Check the seeds daily and water them as needed to keep the soil moist but not soggy.
- Thin the seedlings. Once the seedlings have developed their first set of true leaves, thin them out so that they are spaced about 2 inches apart.
- Transplant the seedlings. When the seedlings have developed their second set of true leaves, they are ready to be transplanted into the garden. Harden off the seedlings by gradually exposing them to the outdoors for a week or two before transplanting.
- Water and fertilize the lettuce. Water the lettuce regularly, especially during hot weather. You can also fertilize the lettuce every few weeks with a balanced fertilizer.
- Harvest the lettuce. Lettuce is ready to harvest when the heads are firm and the leaves are a deep green color. You can cut the lettuce heads off at the base of the plant.
Here are some additional tips for growing lettuce from seed:
- Start seeds indoors 6-8 weeks before the last frost.
- Plant seeds 1/4 inch deep in the soil.
- Space plants 6-12 inches apart.
- Water regularly, especially during hot weather.
- Fertilize every few weeks with a balanced fertilizer.
- Harvest when the heads are firm and the leaves are a deep green color.
