Does anyone know how
I can speed nature up a bit, and get a 50 year old covering of
mossy
stuff in a much shorter period of time?

Paint it with yogurt.

Fresh limestone's a sod, isn't it? If you've got a mossy area
somewhere, you can also uproot bits of it and stick to the new
stonework with very thin glue. If the habitat is suitable for moss,
it'll spread quite quickly; indeed, if it's suitable, the moss will
appear anyhow, especially with Brian's yogurt treatment - thin the
yogurt with water, by the way. If you've got a spot of cowdung to mix
in, that'll help too! Mmm!
