Indeterminate tomato varieties
Indeterminate tomatoes are those that continue to vine and form their flowers along the sides of their shoots and continue to grow and produce tomatoes until their first frost kills them. This variety of tomatoes can attain heights between six to twelve feet and needs the support of tall wooden or metal stakes.
These indeterminate tomatoes can greatly benefit from the pruning of its tomato suckers. Pinching back some of the suckers on indeterminate tomatoes can do wonders for foiling unruly growth. Tomato suckers are small stalks that tomato plants develop in the space between the stem and a leaf branch called the axil.
Traditionally, gardeners will prune tomato suckers off indeterminate tomato plants because they continue to produce leaves throughout the entirety of the growing season. Tomato suckers pull energy from the plant to grow its stalks and leaves, rather than using its energy to blossom and produce fruit.
