I already have a compost bin on my allotment but wonder if there is any
need for a garden incinerator as well? I'm referring to those small
galvanised metal bins with holes in them and a lid on top with a small
chimney.

What exactly are they used for? Apart from burning say, perennial weeds
such as bindweed, I cannot see why I don't chuck stuff straight onto the
compost heap and let it compost there.

Does anyone here use one?
