How much dead grass should you remove after spraying out an old lawn before topdressing and reseeding?
Hey guys, after spraying back an old lawn how much effort would you put into removing the dead grass? I am following the reno guide but there is not too much info on how much to strip it before applying new topsoil.
Cheers
Hey mate, you don’t need to go overboard removing every bit of dead grass. The main thing is to remove as much of the thick, dead material as possible so you’ve got good seed-to-soil contact when you sow.
A good scalp with the mower followed by a scarify is generally more than enough. If you’re bringing in fresh topsoil, you can spread that over the existing surface, provided you haven’t got a thick layer of dead grass underneath.
I’ve been really lazy in the past and just done a mow on the lowest setting, and the end result has been just as good as when I’ve gone to a lot more effort!
