I haven't started any of my seeds inside yet. Up here it's the first of June before we dare transplant seedlings into the garden. And even then we sometimes get stomped on with a surprise late frost. So other than perhaps tomatoes and peppers, in our house nothing gets started under lights until the first of April. Otherwise, the plants just get too leggy.
No tomatoes (except cherry tomatoes that I'm always lucky enough to get bunches of without too much trouble) for me this year. Before last summer, I hadn't planted any full-sized tomatoes for several years. But the past couple of growing seasons had been a little warmer so once again, I was lured into thinking that with a little extra effort, maybe I could get those round, red devils to ripen for me. Last year I did lots of experimenting in the garden (with LOTS of tomato plants) with the thought of trying my darndest to get a bunch of full-sized tomatoes to harvest. I use a lot of stewed tomatoes in soups and casseroles and really wanted to can our year's supply. Remember how I did? Dismal failure. In our climate, you truly do need a greenhouse to be assured of having tomatoes ripen on the vine. Wonder why I can't get that through my head? (Hope springs eternal, as they say!)
Peppers grow on a small enough "bush" for me to protect them with a cold frame type affair over one of my 4' x 8' garden beds so even if the started plants are just eight weeks old when I put them out, they end the season giving us lots of red and green fruits.
