Growing Roma tomatoes

I am trying this (tomato) for the first time and I notice that it looks more like a very thick bush, does anyone know if this is something I should thin out or do I just leave it alone?

roydcole & Group:

Prune Romas just enough to keep leaves off the ground and allow light into the center of the plant,

Indeterminate plants can and should be grown vertically by taking off the sucker stems.

Determinate plants - such as the Romas - will not grow tall, so the only sucker removal is to open up the plant somewhat, and pruning leaves is to keep them off the ground.

And by the way, we recommend you plant indeterminates - anything you're growing vertically - in one row only, on one side of the bed near the ridge. This makes feeding, watering, weeding, and even harvesting easier.
