Determinate and Indeterminate

When selecting tomato varieties, you must choose between plants with different types of growth habits called determinate or indeterminate. All tomatoes are either one or the other.

Determinate varieties (including bush varieties) reach a certain plant height and then stop growing. The majority of their fruit matures within a month or two and appears at the ends of the branches. These are popular with gardeners who like to can, make sauce, or have another reason for wanting most of their tomatoes at once. It might even be that you'd prefer to harvest early and leave late summer for a long vacation.

Most determinate varieties need a cage, but there are some very stocky varieties, such as Better Bush, that have a very sturdy main stems; they don't need much support, just a stake to keep them from toppling in wind and rain. Varieties especially suited to growing in pots, such as Patio and Better Bush, are determinate. Little or no pruning is needed.

Indeterminate varieties continue to grow and produce tomatoes all along the stems throughout the growing season. Indeterminate plants need extra-tall supports of at least 5 feet. Because indeterminate varieties throw out so many shoots, gardeners often prune them for optimum-sized fruit or train them on a very tall trellis. However, if you don't prune, no harm done! You may have seen photos of 10- or 15-foot tomato vines. These are definitely indeterminate types.

Most gardeners grow both types, determinate for large harvests for canning and freezing and indeterminate to get fruit for salads and sandwiches throughout the growing season.

A few varieties are called semi-determinate or compact indeterminate because they are somewhere in between. For best results, give them support.

Symbols for Disease Resistance

Tomato names are often followed by capital letters that stand for resistance to certain diseases. This is very important because these diseases can wipe out a tomato crop.

Other Tomato Terms

Heirloom tomato &#; Any tomato that is at least fifty years old and is not a hybrid.

Hybrid tomato &#; A tomato bred by crossing varieties. Hybrids offer better disease resistance, higher yield, and other improved traits. Our hybrids are not genetically engineered.

Early variety &#; A tomato that matures in 50 to 60 days; these are prized for early harvests and late summer planting for a fall crop. Sometimes we refer to tomatoes that mature in more than 60 days as "early," but only in comparison to their peers. For example, the earliest beefsteak type is only early compared to other beefsteaks. Beefsteaks are typically longer maturing than other tomato types because they are so big!

Question:

Answer:

Determinate and indeterminate refer to the tomato&#;s growth habit.  Determinate tomatoes are small, compact plants.  They grow to a certain height, stop, then flower and set all their fruit within a short period of time.  The harvest period for determinate tomatoes is generally short, making them good choices for canning.

Indeterminate tomatoes continue to grow, flower, and set fruit until killed by the first frost in fall.  Accordingly, the harvest from indeterminate varieties often extends over a 2 or 3 month period.  Yields are generally heavier than determinate types, but are usually later to mature.  Indeterminate tomatoes are large, sprawling plants which often perform best when grown in wire cages or trained on stakes.
