WebThe most common reason why water runs right through is that the soil has become hydrophobic. This means it cannot absorb the moisture as it used to. The main reason this happens is that you have not watered the potting soil regularly. So the materials like peat moss turn hydrophobic. WebThe hydrophobic layer can vary in thickness. There is a simple test to determine if this water repellant layer is present: 1. Place a drop of water on the exposed soil surface and wait a few moments. If the water beads up and does not penetrate the soil than it’s hydrophobic. 2. Repeat this test several times, but each time remove a one-inch ...
