Answer: Tomato seedlings should have 3-4 sets of true leaves before they are set out in the garden. I would move the seedlings outdoors but shade them from the hot sunshine until they become acclimated to being in the great outdoors. Start by giving them just a couple of hours of morning sunshine, increasing the amount of time they get direct sunshine each day. In 7-10 days they should be getting full sun all day long and should be hardened off enough to be planted in the garden. Hope you have a bountiful harvest!
