How to grow lettuce in a container
The fastest, easiest edible plant for absolute beginners — works on a balcony, windowsill, or doorstep.

What you need
A wide, shallow pot — lettuce roots are shallow, so depth wastes soil. 6 inches deep is plenty.
Loose-leaf or butterhead seed packets are easiest. Avoid romaine for a first attempt — slower and pickier.
Planting and watering
Sprinkle seeds across the surface, lightly cover with 1/4 inch of soil. Water gently with a spray bottle so seeds don't wash.
Keep soil consistently damp. Lettuce dries out fast in hot sun. Partial shade in summer prevents bolting (going to seed).
Cut-and-come-again
Once leaves are 4 inches tall, cut the outer leaves with scissors, leaving the center. The plant keeps producing for weeks.
Sow a new round every 2 weeks for continuous harvests. Lettuce stops producing in real heat — pull it and replant in fall.
People also ask
Can I use a regular flowerpot?+
Yes, but a wide rectangular planter gives more harvest. Shallow + wide beats deep + narrow.
Why is my lettuce bitter?+
Heat or drought stress, or too late in the cycle. Harvest younger leaves; lettuce sweetens in cool weather.
How much can I grow in one pot?+
A 12x18-inch planter feeds two people salads for 4–6 weeks if you cut-and-come-again.
