What proportion of shredded prunings of various shrubs is it advisable
to place in the compost heap?

Since I live alone, I don't get a great amount of kitchen waste to add
to the heap, so my compost is mainly shreddings and some of the grass
from the mower. Plus some free home-made accelerator. ;-)

Sounds like an ideal balance! Layer shreddings (brown) with grass
clippings (green) and you really can't go wrong.
