How much pruning should be done on a cherry tomato plant and how far up the plant?
You really don’t need to prune at all. You can remove some of the older yellow or brown leaves at the bottom and pinch off a few of the smaller side shoots toward the bottom to put more energy into the main plant. Cherry tomatoes are usually indeterminate and keep on growing like a vine –that’s one of the reasons they are so prolific. I wouldn’t fuss it too much and just stand back and get ready to harvest a great crop!
