doing that.


Why is that?


Using gravel wastes space that could be filled with soil and roots, and it
doesn't improve the drainage at all. The potting soil just above the gravel
will be the most saturated part of the pot. It's all down to surface tension.
The water doesn't drain out of the soil into the gravel until the entire bulk
of the soil is over-saturated.

The pot should have a drainage hole to allow excess water to drain and that
will be sufficient.
