Can anyone help me with ideas for polystyrene balls from bean bags to be used in the garden. I was thinking perhaps in potting mix or drainage. Is there a way of dealing with them other than sending them to land fill? The bag split and has been sitting outside till I work out how to re-use the thing. Can't be recycled and sewn up again because as I mentioned, it's been sitting outside (rain, insects, dirt etc). Are they toxic? Cheers all.
