Healthy Roots Need Somewhere For Water To Go
A beautiful container can make a houseplant look like part of the room. However, the most important feature is usually underneath it. Drainage holes allow extra water to leave the pot after watering, helping the soil retain both moisture and air. Roots need oxygen as well as water. When potting mix stays soaked for too long, water fills spaces that normally hold air. This can weaken roots and create conditions that support decay.
