When buying a pot, you need to consider the size of the indoor flower. The depth of the pot is selected individually depending on the type and variety of the plant, as well as on the shape and volume of its root system.
For high and lush plants, it is recommended to select clay flower pots, since the weight of their aboveground part can lead to the overturning of a light plastic container, especially when the soil mixture dries.
Most often, when choosing a pot, you need to pay attention to the diameter of its upper part. The container height and diameter should be approximately the same.
The volume of the purchased container or container for an indoor flower that needs transplantation should be oriented towards the volume of the plant's root system. If the root occupies the entire space of the container or even grows into the drainage holes, and even more so it braids the entire earthen ball, then a new pot should be chosen two to three centimeters larger in diameter.
A flower container that is much larger than the root of the plant in volume can harm a house pet. In such a container, moisture will stagnate, and this is dangerous for the development and growth of roots and the entire plant. Containers of such volumes are recommended only for growing fast-growing plants, in which the root system is branched and powerful in size.
