I solved my dilemma, I found a 8ft cattle wire cage that I made long ago and forgot about it. It fits around my Katana tomato container. I secured it with a 5ft fence peg. Now I can let the plant run wild with out removing any suckers. I wonder if my other two indeterminate plants will produce more fruit on a single vine?Katana is a Beefsteak tomato hybrid variety so I would think that your plants will do well without requiring any pruning but sometimes it does help to remove any/all decaying or yellowing leaves…As well as any other leaves that are in the way of your flowers to encourage better growth.
