Morning everyone, just remembered I promised an update as well on the David Grays Product
Works a treat on the Winter Grass (not a spec of the few sprouts remain on the good lawn) and the spot sprays on the huge verge also knocked it out down there.
No effect on clover or nut grass. Will try the Buffalo Pro now its been a couple weeks since the last granular fertilise (311 baileys slow release to get it over the worst of winter) and a week since the mow.
