The Danger of "Overpotting" & Container Volume Math
One of the most common beginner mistakes is assuming that placing a small plant into a giant pot will allow it to grow faster. In reality, **soil without roots cannot drink water**.
When you upsize by 4 or 6 inches, the volume of soil increases by over 300%. That massive ring of wet, rootless soil stays soggy for weeks, suffocating existing root hairs and inviting fatal Pythium fungal rot.
