Hello:

Have a typical colonial, painted white.

The somewhat shady side of the house has a few good size patches of very
light colored
green colored moss on it. (I assume it's moss, but perhaps fungus, algae,
or... ?)

No big deal, but not too happy with it.

Live in New England.

In a few months will be real, real, cold up here.

Questions:

a. Will that kill the moss ?

b. If so, when "dead", will the green color go away ?

Reason I'm asking is that we will be re-painting the house in the Spring,
and if the green color will actually go away, will just wait until then.

Thanks,
B.
