Most novice veggie gardeners have an extra tomato cage or two in their garage or backyard. Here is a clever way to create a mini greenhouse for those plants that you want to take extra good care of: simply plant your starter plant in a pot. Stick a tomato cage in the pot, then wrap plastic wrap around the bottom and through the cage itself to create a little greenhouse. Do not forget to leave space by the pot so that you can still water it.
