Drainage is vital for potted plants. It is always preferable to select a container with bottom holes as opposed to one without, as this provides you with some flexibility to experiment with the watering needs of each specific plant.
Therefore, avoiding using a container without a drainage hole is advisable unless you are familiar with the plant and the amount of water it demands.
The drainage holes enable the removal of extra water and lessen the possibility of root damage. Place a tray underneath to catch any water from the planter.
