Mike grows vegetables on his farm. The tomatoes that he grows are of good quality, but they are small. What can he do to increase the size of the tomatoes?

To increase the size of the tomatoes, one thing he could do is to prune side stems. These are the new branches that grow from the main stem of the plant which signifies overgrowth. Overgrowth will mean that these leaves will not get enough sunlight to grow bigger and also it weighs down the plant. However, when you take out these side stems more of the leaves are exposed to the sun thus they make more energy for the plant which then produce larger fruits.
