Hi there lads, I've got a quick question about this beauty product I found for killing nut grass - "Sedgehammer".
The instructions say mix 1.3g into approx 10L and that this should cover 100sqm.
What I don't understand is what if you are just targeting patches of nut grass on a 100sqm block of land? It might only be 10sqm that actually needs covering (although this is really difficult to calculate when its small patches randomly over the lawn).
If I was soaking the entire yard it'd be a bit easier to work out how heavy to spray it on, but because it's just meant to be used on problem areas I have no idea how much to spray.
Also this is going on turf that is about 4 weeks old, it's started to dig into the soil now. Do you think this should be fine to use?
