My lawn is in a total state; needs scrapping and returfing but I'm not
about to do that now - just want a quick and dirty solution to make it
look a bit better for this season, So I'm going to give it a dose of
weed feed and mosskill (ie, all one dose), after which presumably it
will need scaryfing to get rid of all the dead stuff.

Question - would it be a good idea or not to scarify before dosing? I'm
thinking yes to get rid of as much biomass as possible first, but no
because maybe the moss etc all needs to be intact for the killer to work
properly?

Thanks
David
