Not only does it make for a healthier plant, it also makes for larger, healthier tomatoes! Yes, by all means you can pinch the sucker stems off. They're called "sucker stems" because they "suck" all the nutrients from the main stems. When they are removed, it allows more nutrients to flow through the main plant. Sucker stems can be pinched off of all tomato plants. They can be challenging to keep up with but it's worth it in the long run.
