It does a bit more than that for me, though still not necessary. It keeps a potted plant cleaner. Mine are generally outdoors when it's warm enough and a stone mulch avoids soil splashing on the vegetation. More useful IMO is that a layer of stone on the potting mix keeps the perlite from floating out. I do some immersive type watering and it helps prevent potting mix escaping and floating out .
