Ok so here is the deal I have been gardening in Phoenix for 4 years and last year I decided I am going to try and make it so I have tomatoes year round, and basically I have it figured out for the last year so this fall will be my first time replanting for this method. Long story short here is my question if I plant tomato seeds in late fall and cover them in just a plastic cover without to keep them from freezing will that be enough to keep them healthy till it warms up. The reason I ask is I know things like corn can get stunted growth if they are exposed to cold so as long as I keep the tomatoes from freezing they should be ok for the spring correct? Anyways I would have liked to explain more but I would have two more pages to write. Anyways thanks
