Potting Mix and Drainage

AND that's not all...

The more insidious problem is the classic "perched water table". The
water that remains in the pot will "hang" disproportionately at the
interface between the potting soil and the coarse drainage material
resulting in a nearly saturated layer. Especially in the case of bulbs,
this can be dangerous.

Filling the pot with potting soil results in a more evenly distributed
water load...
