If neglected, bamboo can become an extremely invasive plant. Using a planter box will take care of this. You are preventing the plant from spreading by limiting the root system to a particular area.
Additionally, you may reposition these pots to vary the look of your garden or to provide them with the correct lighting.
If you live in a rental or want to brighten up the exterior of a commercial building, planting pots can be a terrific way to grow bamboo! It is not as enduring as bamboo that is planted underground.
