I've never used these bags in my compost bins before because I didn't
really trust them to break down. However, on buying a new compost
caddy, I find there are some inside.

Have others here found that these bags degrade well (completely
disappear would be good), or do they persist in the outdoor compost bin
months hence, only to be picked out by hand while riddling the compost?
Other irritants of this kind are tea bags and the supposedly
degradeable jiffy-type fibre pots.

When I first moved here, the previous residents had obviously used
plastic sacks all over the garden to suppress weeds. The garden was
scattered with thousands of shreds of black plastic bag:~((. This is
precisely what I do not wish to find in my usually perfect compost.

So the question is: do they really break down, or don't they?
Thanks for your time.
