I've just pressure washed moss from a tarmac tennis court now I need to
prevent
it from coming back. Suggestions include Jeyes Fluid, Jeyes
Path Patio and
Drive, Armatillox and Bleach. Anyone know which is best
and how often I need to
apply? Court is shady, often damp and
surrounded by trees which obviously I
can't do anything about.

In this country you don't stand a chance of ridding yourself of moss
permanently just as in a desert you don't stand a chance of growing it.
And with the conditions you describe you really are on a hiding to
nothing (((((((

I'm afraid you will have to resign yourself to pressure washing a couple
of times a year.
