Almost all types of tomatoes require a climbing aid. Spiral rods around which the main shoots can wind themselves are ideal for this.
In order to make your tomato plants produce more fruits, you should be growing the plants with one sprout only. This means that all other young shoots need to be broken off, as well as all other lateral shoots. In addition, the head of the plant can be cut above the fifth raceme. This way, the strength of the plant is directed to these five racemes, and the plant will finally yield a better harvest.
