I have a beefsteak plant and lots of large green tomatoes, but they aren't turning red. I'm wondering if I am being impatient or if there is something wrong with my plant. The biggest I have is about 1 lb and looks wonderful, but not turning red. There doesn't seem to be any diseases on the leaves or the tomato itself. I am at a loss, as this the first time I have grown beefsteak. I am in Phoenix and the plant gets morning sun. I do have green peppers and two types of squash in a garden size of 20 X 10 area. Sure hope you have an answer for me.
