topping tomato plants
I have never done this before (except in the late summer. I get the minimal amount of sun so end up with 8-9 foot plants which extend way above the cages. My brother in law (with my plants) grows tomatoes that never get over 4 feet tall and spread out 5 feet. He's got almost total sun so the plant never needs to grow tall. He gets twice as many tomatoes as well. Can I keep topping off a plant (from the beginning) to make it grow wider? Would such a plant produce more (despite my minimal sun)_?
