I've just got my new free compost bin from the local council and noticed
it's got a couple of what appear to be air holes in the side. I had been
thinking about making a similar modification to my two Sankey compost bins
which are pretty much air-tight.

Is it worth doing or will it cause problems? If it is worth doing, how many
holes would be best?


I wouldn't have thought it was worth bothering with. I doubt it will
improve heap aeration much if at all, and will only really contribute to
drying the heap out. I'd leave them as they are.
