Large-vined tomatoes benefit from being grown in wire cages. They show fewer cracks and sunburn, ripen more uniformly, and show fewer green shoulders than tomatoes which are pruned and tied to stakes or allowed to sprawl on the ground. However, tomatoes that are pruned and tied to stakes will produce fruit earlier than those grown in cages. Erect cages soon after plants have been set out. Otherwise, breakage often occurs when you try to train stems which have grown too long. One material suggested for cage use is concrete reinforcing wire (6-inch mesh). This wire comes in widths up to 72 inches. Cut a piece long enough that when it is bent into a circle the diameter of the cage will be large enough for the plant as it grows. Anchor the cage to the ground with stakes to prevent it from blowing over. This type of cage provides good support and allows you to reach through to pick tomatoes. However, this wire will rust, so after making cages, it's a good idea to paint them with rust resistant paint. Galvanized fence wire lasts many seasons without painting. Be sure to get 4- to 6-inch mesh so your hand will fit through for harvesting. Galvanized fence wire comes either welded or woven. Since welded joints occasionally break, woven is the best type to use.
