I very rarely use drainage crocks in pots with small drainage holes.
Where I do need crocks, I use slate pieces and broken crocks dug up from
the garden - masses of it round here :~)). I have also used polystyrene
in a huge pot to limit the amount of compost I need to use, as well as
for drainage.

In winter, if I have large slabs of polystyrene, I use it to stand pots
on so the roots aren't near the frozen ground. I find this quite helpful.
