Knowing tomato terms helps you choose the right varieties for your needs

For gardeners shopping for tomato plants, the range of options can be daunting, especially if you’re looking to expand beyond your tried-and-true varieties. As you explore tomato plant offerings, you’ll encounter terms like “determinate” and “indeterminate” used to describe different types of tomato plants. Learn about their differences, characteristics, and how to make the most of each type.

Determinate (bush type) tomato plants are known for their “predetermined” or compact, bushy growth habit that makes them perfect for smaller spaces or containers. These varieties are often easier to maintain and typically stop growing in height once they reach around 3 to 4 feet tall. They set fruit over a short period, typically within a few weeks, often producing a concentrated crop all at once – a bonus for gardeners who seek a large harvest for canning.

Indeterminate (vining) tomato plants will grow extensive, vigorous vines often over 5 feet, and require trellises or stakes for support. These types of plants offer an extended harvest period, providing a steady supply of fresh tomatoes from summer to fall. These plants continually produce fruit throughout the growing season until they are stopped by frost or disease. 

Choosing whether to grow determinate or indeterminate tomato plants depends on your gardening goals, space constraints and preferred harvesting methods. Selecting the right varieties of tomatoes will help you enjoy a bountiful harvest of delicious, homegrown tomatoes.
