Trusses & Clusters

Trusses grow on cordon (tall) varieties and clusters grow on bush varieties.
Clusters, or flower clusters grow at the end of the leaf branches on bush varieties whereas trusses grow directly from the main stem of cordon types.

The great thing about bush varieties is that you can just leave them to "get on with it" without the need for pruning side shoots and hopefully they'll produce lots of fruit from their flower clusters.

Where cherry varieties are concerned, the amount of flowers and fruit aren't a problem.
However, a large number of flowers on a bush variety that produces large fruit may need a little pruning or removal of some flower buds in order to reduce the task of growing a large amount of large tomatoes.

It would be reasonable to expect up to a hundred cherry tomatoes from a well grown bush plant but perhaps only ten or twenty from a plant the produces large fruit.
