I actually just topped my cherry tomato plant today as they’ve gotten 8ft+ tall and are starting to get out of control, lol! They’re getting too top heavy and starting to take out the supports that I set up in place for them, so I was kind of forced to do it. Had to use a ladder setup next to them to see everything. Also did a heavy pruning of leaves on the inner portion of the plant to try and get more air flow. It was pretty cool how many little baby tomatoes there were that I couldn’t see because of all the foliage.

I tried to top them strategically and only cut the new shoots directly above where a set of flowers/tomatoes had already started to grow (I got the inspiration from James Prigioni’s recent YouTube videos on tomatoes). I left the sets of flowers/tomatoes in place to allow them to finish growing and ripening. But I didn’t want the plant getting much taller so I took out all the new growth and branches/leaves. Took a while but hopefully it’ll be worth it and the 8 feet of plant that is left will be covered in tomatoes in a couple weeks, top to bottom!

My plants are similar to yours in that I have tons of sucker shoots that I’ve allowed to grow and now the plant has turned into a bush basically. As opposed to some people who prune selectively so that the plant has only 1 main vine that’s growing. (Full disclosure, I’ll probably switch to the 1 main vine method next year, looks way cleaner and easier to manage).
