Many paste or Roma tomatoes are determinate varieties, such as 'San Marzano' and 'Amish Paste'. Some others have been bred to be determinate, so they can be harvested in quantity all at one time. These include 'Celebrity', 'Marglobe', and 'Rutgers'.

How can you tell if tomatoes are determinate or indeterminate?

Determinate tomatoes commonly have leaves that are closer together on the stem, making them look bushier. Indeterminate varieties have leaves that are spaced out more and look more like vines. Check the flowers and fruit production.

Which tomatoes are determinate and which are indeterminate?

The determinate tomato plant is often grown in a cage or even without support, as it has a more compact shape. The determinate tomato varieties also produce most of their fruit on the terminal end. The indeterminate tomato varieties have much longer stem growth, which continues to grow until cold weather arrives.
