I know that you can top a pepper plant early on and essentially force it to grow into a bush form but can you do the same for tomatoes? Im growing indoor hydroponic indeterminates and my grow space only has a limited height. Will topping the tomatoes decrease potential fruit output?
I can’t speak to personal experience with it, but there was some recent discussion of an old French pruning method over on Tomato Junction that kept plants relatively short.
