Major cluster-tomato producing states in the United States are Texas, Arizona, California, and Colorado. A few small growers in Florida have grown cluster tomatoes in the last two years, and more space is planned for the coming year. Greenhouse culture of cluster tomatoes is similar to that used for traditional large beefsteak types. The crop is trained and supported by strings on an overhead trellis system. Most currently grown cultivars tend to have taller plants requiring high trellis systems.
Most growers now use bumblebees for pollination.
The clusters are harvested by clipping the main cluster stem from the plant. All tomatoes on the cluster remain attached, and range in maturity from breaker to ripe. Harvested clusters are usually marketed in a mesh bag or in a one-layer box. Many cluster tomato cultivars have outstanding flavor and appearance to compete with the best of the vine-ripe tomatoes sold. In addition, consumers are highly attracted to the tomato aroma provided by the stems of the cluster.
