Determinate vs. Indeterminate Tomatoes

To unravel the growth habits of San Marzano tomatoes, it’s essential to grasp the fundamental botanical terms “determinate” and “indeterminate” as they apply to tomato plants. These terms offer insights into how tomatoes grow, produce fruit, and ultimately complete their life cycles.

In the world of tomatoes:

  • Determinate: This term refers to tomato varieties with a more compact growth habit. Determinate tomato plants typically grow to a certain height, set their fruit in a concentrated period, and then cease active growth. They are often preferred for canning and preserving purposes due to their synchronized fruiting.
  • Indeterminate: Conversely, “indeterminate” describes tomato varieties with a vining growth habit. Indeterminate tomato plants continue to grow and produce fruit throughout the growing season, with no predetermined endpoint for their growth. They are favored for fresh consumption and can yield fruit until the first frost.

Understanding these terms provides a foundational understanding of how tomato plants, including San Marzano tomatoes, behave as they mature and bear fruit.
