A friend of mine has taken on an allotment which has a lot of grass,
which has been cut.
An elderly allotmenteer told her to take off the turf, let it dry,
then burn it. This surely is sacrilege. I would stack it and let it
convert to loam. Leave it long enough and the weeds will die off or
can be sifted out. Isn't that how loam is made, in a turf stack?
