    Actually, adding gravel or sand to the bottom of a container is a bad idea, since it may push the “perched water table” up into the root zone. (The PWT is the horizontal wet zone in the pot where gravity pulls down & the water retention properties of the medium pulls up. It is dependent upon uniformity of particle size in the pot.) If you have huge pots, adding 1/4 to 1/3 of mulch to the bottom can be ok to save on potting soil, but for most pots the adding of pot shards or whatever on the bottom for “drainage” is a myth. And a detrimental one at that. If the PWT is hovering at the root zone, (and not below) the plant will either suffocate, or its roots will rot.
