Because the root system of Phnom Penh is not very developed, it is not necessary to use flowerpots with too large diameter or too deep to plant it. Specifically, if you just want to raise a plant and don't want to raise it very high, then you can choose a pot with a diameter of about 25cm.
If you want to keep more plants in the same flowerpot, you should naturally increase the diameter of the flowerpot. This can provide them with more growth space and prevent them from interfering with each other's growth due to competing for resources. Specifically, if you want to plant about three plants in the same basin, you can choose a flowerpot with a basin diameter of about 30cm, and if you want to plant more, the basin diameter should be larger
For some tall plants, such as those over 2m, the diameter and depth of the selected flowerpot should also be larger. In this way, it can give it more space to grow, so that it can grow
In addition to the size, the material is also very important. Because in the process of raising it, if the flowerpot is not suitable, it is easy to cause growth problems. In particular, you can use pottery basin or clay basin. Because they have good air permeability, they can reduce the probability of withered roots.
