I was under the impression that broken pieces of flower pots were put into the bottom of larger pots as they retained moisture as well as stopping soil falling through the holes in the bottom of the pot.
A number of posters have told us they use other "stuff" such as bottle tops, polystyrene, etc. These do not retain moisture.
I am confused.
