Beefsteak tomatoes tend to be indeterminate varieties, though some are semi-determinate, and need a sturdy support put in place in order to support their tall growth and heavy fruits. It is best to plant beefsteak tomatoes deep and to pinch out any side shoots from the main stem regularly. Beefsteak varieties of tomatoes need lots of space and an especially sturdy cage, trellis, or stake as their large fruit can weigh over one pound and potentially damage the plant if it is not properly supported.
