I have a habit of buying lettuce seeds when I find them. We favor the leaf lettuces like romaine. I started seeds from 2021 and did not expect them to start. They all did. We just do our lettuce in big planters now. No bending over. Leaf lettuces will need at least 6” of soil in a planter. You will get beautiful big heads if you can sew one seed at a time. I use peat pots. Leaf lettuce will grow if crowded but will not get very big.
That sounds great! Now I’m really looking forward to putting in the effort to do lettuce in containers.
I thought of another benefit — gophers won’t have nearly as easy a time destroying everything if it’s in containers. Let the pests go ruin someone else’s hard work. :-)
