Hello, I've planted some tomatoes with a Tomato Rocket in a pot about two months ago. Its a roll with seeds in it I think they are roma tomatoes. 2 months later, I,'m realizing that i should've thinned out more of the sprouts as i'm stuck with about fifteen plants that are about three feet tall in the same large Pot. Its my first time growing tomatoes and I started them in a apartment without knowing that I should've thinned them out to about 2-3 plants. They do have a few flowers coming out and about 3 tomatoes already about half grown. The problem that I have right now is that my pot is vastly overcrowded, The stem is not as thick as it should be and the leaves take almost all the space in the support cage, I have tried thinning out the leaves but I don't want to destroy the branches with flowers on them. I am wondering If its too late to maybe cut a few of the plant at the base to give the stronger ones a chance to get thicker and if its a good thing to do to get the most tomatoes.
I will attach a photo of the plant taken today and when it was growing inside my appartment.
