Why aren't my tomatoes red?

The method for solving the problem that tomatoes are not red includes:

First, when planting, control the spacing between plants to ensure that tomatoes have a large growth space.

The second is proper pruning. Why do you pick ripe tomatoes every day? You are worried that the uneven distribution of nutrients will affect the growth of other fruits. In the process of tomato growth, it is necessary to prune and prune in time, so that nutrients can be concentrated on flowering and fruiting, and the fruit setting rate can be improved.

The third is scaffolding. There is an old saying in the countryside, "If you want to hang all the branches, you must set up scaffolding as early as possible." By building a shed, you can ensure the growth space of the fruit and receive enough sunshine.
