The message
from Inge Jones contains these words:

Well I'm not going to have a compost heap of my own and the neighbours
don't either as that would take up about 20% of the planting area, so
what's the best easily-available bagged stuff to spread each year?

Mushroom compost? (Try yellow pages under mushroom producers). Or,
your local council may sell compost it makes from green-waste
collections.
