Why keep it clear of moss?
Moss on the roof helps to keep the heat in.

It's usually a sign of a wet climate. Surely, a blanket of wet moss
would act as a small refrigerator :-)

But apart from its rapid growth and water-damming properties, moss
tends to be rather acid and a build up can quite rapidly damage some
roof materials.

The moss on my roof drains when the rain stops.

It hasn't caused any damage to my roof and it's been growing for about
50 years.

It didn't grow on my previous house roof because it was tiled. Some
tiles slipped or blew off occasionally. I can't help but think that
moss holds some roof materials in place.

It hasn't damaged my roof, either, but when clumps of it come loose,
they can clog the drains.

In The Garden of Evening Mists, the woman learning from the Japanese
master is set to making balls out of copper strips. These are thrown into
the pond and sink. He tells her this is to deter algae. Has anyone ever
tried it and I wonder if it would work on the accursed duckweed?

Who would want to trhow a copper ball into hs/her sink?.....:-)


Anyway, meny years ago my bro'in-law ad a small pond which was pea green
with algae. By chance he came with me to a local pet shop/fish shop where I
bought some bags of Daphnea. He decided to get some for the fish in his
pond. He dumped his Daphnea into the water and within two days the water was
Gin clear. Amazing result.

The Dutch used to put powered copper electrodes in the water of their
large boat
houses to reduce weed. It's probably banned now.
There are no fish left in the IJsselmeer because either
a) Over fishing - government version.
b) The water is too clean, so no food for the fish to feed on. Fishermen's
version.
There is going to be a three year ban on fishing.

Martin I hope we are not getting confused with "Cathodic Protection" which
is a whole different ball game.

When I was an aquarist I put more effort into keeping daphnia than the
fish!

This morning there were small oily streaks on the surface of one of the
ponds. We think that usually means the heron has come calling!
