How tall can tomatoes grow? What is the tallest and thickest?

If it is not controlled and fertilization is better, it may be about 2.5 meters, but there are fewer tomatoes. The average farmer will control its height to a certain limit, generally around 1.5 meters, so that the fruit is the most.

Tomato trees are a little calcium deficient. If you reach a certain height, you need to support it on the ground with a wooden stick to keep standing. Generally, the thickest part is near the root, about 3 cm. If it is high, it is estimated that it will not exceed 5 cm.

I hope my answer will satisfy you.
