Roma VF Tomato – Determinate or Indeterminate?

Roma tomatoes are a garden staple known for their slender, oval shape and meaty flesh that make them perfect for sauces and canning. But when it comes to growing them, there is often confusion around whether Roma tomatoes are determinate or indeterminate. The answer to this question is important, as it affects how the plants are cared for and supported. In this article, we’ll take a deep dive into Roma tomato growth habits and clear up whether popular varieties like Roma VF are determinate or indeterminate.

Understanding Determinate vs. Indeterminate Tomatoes

First, let’s cover the key differences between determinate and indeterminate tomato varieties.

Determinate tomatoes, sometimes called “bush” types, are more compact plants that grow to a fixed size, usually about 3-4 feet tall. These plants set and ripen most of their fruit at once over a 2-3 week period. Determinate varieties are great for container gardening or situations where space is limited.

Indeterminate tomatoes are also called “vining” types. They continue growing and producing fruit all season until killed by frost. Without pruning, indeterminate tomatoes can reach 6 feet tall or more. They bloom and set new fruit progressively over an extended harvest period. This makes them ideal for fresh eating all summer long. However, they require more space and support in the garden.

• Determinate – Grow to fixed size, ripen crop all at once, great for containers and small spaces
• Indeterminate – Continue growing all season, extended harvest period, need more space and support

Now let’s look specifically at whether popular Roma-type tomatoes are determinate or indeterminate.

Are Roma Tomatoes Determinate or Indeterminate?

The short answer is that most authentic Roma varieties are determinate. This includes beloved heirlooms like ‘Roma’ and ‘San Marzano’ as well as newer developments like ‘Roma VF’.

Roma tomatoes trace their ancestry to Italy. Over centuries, Italian farmers selected for a compact, upright growth habit. This allowed the meaty, plum-shaped fruits to fully ripen while concentrated on a short bushy plant. As a result, authentic Roma types exhibit determinate growth.
