Trusses grow out from the main stem, like branches, and are what will carry the fruit. You pinch out side shoots, which grow between the main vertical stem and the fruit trusses. The pinching out method of pruning means you support one single stem with a cane or string, and it also staggers the production of buds throughout the season, creating in multiple, high-quality harvests – yum! If left untrained, tomatoes will produce a large number of flowers on a big mass of foliage, which puts pressure on energy reserves, results in poor quality pickings and is difficult to support.

You can also pinch out the top of the main stem (or growing tip) to stop the tomato plant growing too tall. Pinching out is an easy process of removing extra side shoots with your fingers, so the plant puts its energy into growing one single stem with fewer branches and larger fruits.
