Q&A for How to Grow Lettuce Indoors

Before preparing your salad, cut your lettuce in a way that you can keep the lower part of it where the root is, but be sure to keep the leaves attached to that lower part so they can regrow. Place the lettuce piece on a container with cold water. The water should not cover all the lettuce, just the root part, and it should be in a place where it gets sunlight, but not too direct. You can change the water once a day or every 2 days. You will see how beautifully your lettuce regrows!

There are several varieties of lettuce that thrive indoors. These include Garden Babies, Merlot, Baby Oakleaf, Salad Bowl, Lollo Rosa, Black-Seeded Simpson, Tom Thumb, and Red Deer Tongue. If you aren't sure, purchase your lettuce from a local nursery and ask about varieties that do well when grown indoors.

Yes, you can absolutely grow lettuce in pots. If you're starting them from seed, fill a pot with a seed starting mix and plant the seeds about 4–6 in (10–15 cm) deep. If you're planting seedlings, plant no more than 4 per pot so they have enough room to grow. Place the pot in a sunny location and water them whnever the leaves begin to wilt.

Lettuce thrives when it's grown in full sun. However, it can also tolerate some shade. If you're growing lettuce in a pot, place it outside in a sunny location or near a sunny window indoors. If you don't have a location that receives continuous sunlight, make sure you place it in a location that gets at least 8 hours of sun a day.
