If water runs straight through your pot without soaking into the soil, the potting mix has likely become hydrophobic. This happens when soil dries out too much and begins to repel water instead of absorbing it. As a result, water flows down the sides of the pot and out through the drainage holes without properly rehydrating the root zone.
This is a common issue with houseplants that have been left dry for too long, particularly in mixes that contain peat or organic materials that shrink as they dry.
To fix the problem, try bottom watering or soaking the pot. Place the plant in a tray or bowl of water for 10–20 minutes, allowing the soil to slowly absorb moisture from the bottom. Afterwards, let the pot drain fully before returning it to its usual spot.
If the issue happens repeatedly, it may be a sign that the potting mix has broken down over time. Refreshing the soil with a quality mix, such as Simply Houseplant potting mix, can help restore proper moisture balance.
