When is the correct time to put tomato plants in a non heated greenhouse.?

You can put them in there when there is no chance of frost inside the greenhouse.I would recommend that you wouldn't want your hat below 50 degrees even at night. I have had tomatoes wilt a little below 50.

Reply:End of May beginning of June is early enough in the U.K. You can keep your seedlings and plants indoors until they are a good 6" tall.Word of warning.Do not put them where it is too warm otherwise they will go all leggy and you will get thin spindly plants.
