growing lettuce

I overwinter lettuces (and mustards) in unheated greenhouses at the plot for early spring harvest. I've successfully done this with Winter Density, Brune d'Hiver, Marvel of 4 Seasons, Arctic King and Hilde II (although I grow Lobjoits, I've never tried to overwinter them). I usually sow September time and put them in the ground mid-late October after the toms come out. They tend to just tick over till early Feb before starting to grow. We harvest from early March to mid-end May (I pick individual leaves from several plants rather than taking a whole head which I find makes them last longer).

Interestingly I planted 2 Multigreens outside last July and harvested from the plants from August to October. They stayed in the ground overwinter and began to grow again in March and have been providing a lot of lettuce since (a couple of weeks off at the end of April when down to just the cores excepted). They are a fantastic lettuce and appear to be unaffected by pests, including pigeons. I'll be overwintering a few of these this year.
