I'm considering three kinds of chemical treatment, but I am not sure of
effectiveness or risks to plants or to the pond we have about 2 yards
distant (it does have a constant good flow of water to cleanse it.
Chemical treatments under consideration: dichlorophen, iron sulphate,
and copper sulphate.

Any advice or experience appreciated.

We have very mild but wet winters and moss takes over all my rockery,
growing rapidly all over the stone walls and the soil and submerging
the rock plants. Many of these die off because their stems and roots
are submerged in moss which is a constantly wet sponge. I've tried
improving drainage, adding lime, placing gravel around the plants etc.,
to no avail. It is impossible to comb the moss out of many of the
creeeping rockery plants. It's not really a drainage problem: the moss
proliferates all over the stone walls. Its basically a mild wet winter
climate. Oddly, we don't get a moss problem in the lawn, probably
because we allow the grass to grow in winter to say 3inches (or maybe
its just too wet to cut!)

Sounds like too much nutrient in the water. Where does the water come
from?
