Determinate vs Indeterminate Tomatoes

Determinate and indeterminate describe how a tomato plant grows, and it is the single most useful thing to know before you plant. One is a bush that ripens its crop in a rush; the other is a vine that keeps going until frost. Neither is better; they are built for different jobs.

What the terms mean

A determinate tomato is a bush. It grows to a fixed size, usually 2 to 4 feet, sets its fruit, and ripens most of it in a concentrated window of a few weeks, then it is largely done.

An indeterminate tomato is a vine. It keeps growing, flowering, and fruiting from the same plant until cold or disease stops it, often reaching 6 feet or more and bearing over two to three months.

Which to grow

Pick determinate if you want a concentrated harvest for canning or sauce, if you are short on space, or if you are growing in a container. Most paste tomatoes and patio types are determinate.

Pick indeterminate if you want a steady supply of fresh fruit all season. Most famous heirlooms and cherry tomatoes are indeterminate, and they reward a long season.

Support and pruning

Determinate plants are compact and need only a stake or short cage; do not prune the suckers, since that just removes fruit.

Indeterminate plants need a tall stake or a sturdy cage and benefit from some sucker pruning to keep air moving and fruit reachable.

Common questions

Which is better for containers?
Determinate and dwarf types, which stay compact. Indeterminate vines outgrow most pots.
Which one yields more?
Indeterminate plants usually yield more total fruit because they bear over a much longer window, though determinate types give a heavier single flush.
How do I tell which a variety is?
Every profile on this site lists the habit in its grow-trait card, and the browse filters and chooser let you sort by it.
