It’s not necessary to prune tomatoes. However, in my garden all the tomato plants get a little pruning. Staked and trellised plants need the most because you want them to grow only one or two main stems which will make the plants easier to tie up.
Pruning means pinching off the shoots, or “suckers,” that grow out from stems right above leaf branches. By restricting the vine growth somewhat, you’ll get bigger tomatoes. If you let these suckers grow, each becomes another big stem with its own branches, blossoms, and fruits— even its own suckers. I prune my plants in cages and those growing freely early in the season, and then I let them grow. You should go on sucker patrol at least twice a week during the heavy growing season to keep your staked plants from getting hard to control.
