I have already planted my tomato plants. I don't do tomatoes from seeds anymore, the plants are just so much easier. Make sure your soil is rich, fertilized and ready for planting. Depending on the rain you get, water maybe every other day. You don't want to over water them, but you really don't want the soil to dry out. I like to plant a couple cherry tomato plants and then a couple beefsteak plants. Be sure to pick them often if you want to grow a good amount. Good Luck!
