Determinate, Indeterminate, Semi-determinate

• Determinate tomatoes means they will stop growing, are bushy, and get about 3 feet (.91 m) tall. Examples of this type include Pik-Red, Early Girl, and Super Bush.

• Indeterminate tomatoes don’t stop growing, and produce a lot of suckers from the main stem of the plant. If conditions are good, those suckers can flower and set fruit. Examples of this type of growth habit include ‘Big Beef’ (most of the beefsteak types), ‘Supersonic’, and ‘ig Boy’.

• Semideterminate plants have habits of both. Examples would be ‘Celebrity’ and ‘Mountain Pride’.
