This makes tomato plants a popular option for vegetable and fruit gardens across the country. As the name suggests, this type of tomato plant's growing isn't fixed; only the first frost will signal that its season has come to an end. This pruning trick, as a result, doesn't apply to determinate tomato plants. A few indeterminate tomato varieties include 'Brandywine,' 'Sungold,' and 'Cherokee Purple' (a slicing tomato). Because indeterminate tomato plants continue to grow, pruning away the suckers helps out with energy conservation.
