Lettuce

I have been researching all of the vegetables, fruits, and flowers that I am planting this year. But, I spent so much time focusing on corn and flowers that I waited until today to look up lettuce. I have found that they like the cold and hate the heat so planting early is better. The first recommended planting date is around the 15th of march. So by that date I should already be growing some inside to transplant out. I haven't even tilled the garden yet. Where the garden will be is still yard and where I would grow transplants (my porch) is still a mess. I think I will go home today drill a few holes in stumps and clean the porch off.
