Did You Know?
1. Did you know that indeterminate tomatoes continue to grow and produce fruit throughout the entire growing season? Unlike determinate tomatoes that have a predetermined height and set number of fruit, indeterminate tomatoes can grow indefinitely and keep producing as long as weather conditions are favorable.
2. Indeterminate tomatoes are often referred to as “vine” tomatoes due to their growth habit. These plants tend to grow long, sprawling vines that require sturdy support systems such as cages or trellises to keep them off the ground.
3. If you’re looking to save seeds from indeterminate tomatoes, make sure to choose open-pollinated varieties instead of hybrids. Open-pollinated varieties allow you to collect seeds that will produce plants similar to their parent, while hybrids can result in plants with unpredictable traits.
4. Pruning indeterminate tomatoes can help improve airflow and sunlight exposure, leading to healthier plants and better fruit production. By removing the “suckers” that grow in the crotches between the main stem and branches, you can redirect the plant’s energy towards producing more fruit.
5. While tomatoes are typically grown in traditional garden beds, indeterminate tomatoes also thrive in containers. This makes them a great option for urban gardeners or those with limited space. Just make sure to choose larger pots (at least 5-gallon) to provide enough room for the plant’s extensive root system.
What Are Indeterminate Tomatoes?
Indeterminate tomatoes, also known as vine or cordon tomatoes, are varieties that grow long, branching vines and produce flavorful fruits in small clusters over an extended period. Unlike determinate tomatoes, which have a compact bush-like shape and a predetermined height, indeterminate tomatoes can reach heights of 8-10 feet or more and require support from staking or heavy-duty tomato cages.
These tomatoes continue to grow until they are killed by frost or disease, making them great for an extended harvest. Indeterminate tomato plants produce flowers and fruit sequentially throughout the season, resulting in a continuous supply of fresh tomatoes. Their larger and sprawling nature makes them stand out when compared to the more compact determinate plants.
Most tomato varieties are indeterminate, producing flowers from the main central stem as well as off-side shoots. They are chosen for their exceptional flavor, and many of the best-tasting tomatoes come from indeterminate plants. In fact, the tallest tomato plant ever grown was an indeterminate plant of the SunGold variety, reaching a staggering height of 65 feet. Additionally, the heaviest tomato on record was an indeterminate plant of the Domingo variety, weighing a whopping 10 pounds 12.7 ounces.

Growing Indeterminate Tomatoes: Support And Pruning
When growing indeterminate tomatoes, it’s crucial to provide them with proper support since they can grow tall and become heavy. Staking or using heavy-duty tomato cages is essential to prevent the plants from sagging or breaking under the weight of the vines and fruits. Tomato cages made from animal fencing are commonly used by gardeners for this purpose.
Indeterminate tomatoes may also benefit from pruning to help control their size and shape, as well as increase air circulation. Pruning involves removing unnecessary foliage and side shoots, which allows the plant to focus its energy on producing fruit. Additionally, pruning can help prevent diseases by improving airflow and reducing the risk of moisture buildup.
However, it’s important to note that pruning indeterminate tomatoes is not required but can be considered if necessary. Some gardeners prefer a more natural, unpruned approach to allow the plants to grow freely. The decision to prune or not ultimately depends on personal preference and specific growing conditions.
Comparing Indeterminate And Determinate Tomato Plants
Indeterminate tomatoes differ significantly from determinate tomato plants in terms of their growth habit and characteristics. While indeterminate tomatoes grow indefinitely until they are killed by frost, disease, or intentional pruning, determinate tomatoes have a predetermined maximum height and tend to have a compact bush-like shape.
Indeterminate tomato plants produce long vines that can reach a height of 10 feet or more, whereas determinate tomato plants typically reach a height of around 3-4 feet. Due to their sprawling growth, indeterminate plants require more attention and support than determinate plants, which only need minimal support.
Interestingly, indeterminate seedlings tend to become leggier as they grow, stretching toward the sunlight. On the other hand, determinate seedlings remain bushy and compact. This distinction can be helpful in identifying the type of tomato plant and understanding its growth pattern.
