How to choose flower pots

When choosing a flower pot, you should also pay attention to the size, and the height should be appropriate. If the flower pot is too large, it will affect the appearance like a thin person wearing big clothes. Moreover, if the flower pot is large and the plant is small, the plant's ability to absorb water is relatively weak. After watering, if the pot soil remains moist for a long time, it will be difficult for the flowers and trees to breathe, which can easily lead to root rot. The flower pot is too small, looks top-heavy, and affects root development. In addition, there are three points for reference when choosing the size and height of the flowerpot:

The diameter of the mouth of the flowerpot should be roughly consistent with the crown diameter of the plant;

Plants with mud balls, After placing the flower pot, there should be a 2-4 cm gap around the flower pot to facilitate the addition of new soil;

For plants without mud balls, the roots should be able to stretch out after being placed in the flower pot. Not suitable for bending. If the taproot or fibrous roots are too long, they can be pruned appropriately and then planted in a pot.
