Total yield is lower than alternate training methods. If the lowest sucker is allowed to develop into a second stem, the additional foliage should reduce the occurrence of sunscald. Staking is not recommended for the shorter growing, determinate tomato varieties because yields will be drastically reduced. A popular method of training tomatoes that requires less attention is the wire cage. A tomato cage can be constructed from concrete reinforcing wire or similar material.
Manufactured cages are also available at garden centers.
When constructing a wire cage, the mesh must be large enough to enable you to pick the fruit. A wire cage 20 to 24 inches in diameter and 4 to 5 feet tall is excellent. For greater stability, drive 1 or 2 stakes into the ground next to the cage. Then fasten the cage to the stakes. Plants grown in wire cages don't need to be tied to the cage or pruned.
