I've just used this product for the first time on my new *very* mossy
lawn. I did it about three days ago, spreading by hand (14kg bag, 13m
x 20m lawn). It rained well the next day (ie two days ago). The moss
is starting to go black, but only in certain spots. I'm now worried my
spreading was not very even. Will this patchiness even out? Does it
need to rain more? Do I need to water it in some more? What is the
timescale of the effect of this stuff? Any advice gratefully received
by this novice!
