The Difference Between "Indeterminate" & "Determinate Tomatoes
Determinate tomato plants are those that will produce their crop all at once and ripen all at once. Also referred to as "bush" variety. They typically grow about 4 feet tall. Determinate plants are usually (but not always) compact and more easily manageable. Popular determinate varieties are Roma, Rutgers, and Margloble.
Indeterminate will produce their crop all throughout their growing season. The vines usually grow very long from 6 - 20 ft. And have to be staked or trellised as you'll see below.
Some popular varieties are Black Krim, Cherokee Purple and Brandywine
Some other examples of indeterminate vegetables are squash, cucumbers and green beans. Typically indeterminate plants will grow long vines.
