Determinate tomatoes are a type of tomato plant that grows to a fixed height and produces fruit all at once. This growth pattern makes them ideal for gardeners who want to harvest their tomatoes in a short period. They typically require less staking and support compared to indeterminate tomatoes, which continue to grow and produce fruit throughout the season. These tomatoes are often used for canning and cooking because they ripen simultaneously, making it easier to process large quantities. Popular varieties of determinate tomatoes include Roma and Celebrity, which are favored for their flavor and consistent yields.
