Pruning tomato plants is somewhat a matter of personal choice. Some indeterminate plants grow so large and heavy that it is impractical to let them reach full size, or they may try to set more tomatoes than they can support, or more than can mature by the end of the season. To complicate matters, excessive pruning can reduce the amount of energy the plant can produce and thus reduce yield, can expose the tomatoes to excessive sun and thus cause sunscald. On the other hand, pruning can help increase air circulation within the plant to reduce disease problems and can speed ripening by allowing more sunlight to the interior of the vine. It's a matter of personal preference. In essence, you prune off the suckers that develop on the lower part of the main stem of the tomato plant. This results in a single upright stem rather than a bushy like plant.
