I've recently taken over a very nice property with couch grass front and back. It seems to be very long and the owner has mentioned that perhaps it needs De-thatching. It has been/can be cut at a level 6 (Honda Hru 216) but I've started cutting it at at level 5 to try and bring it down and perhaps take out a bit of the thatching at the same time. Ideally, I'd like to be able come and mow it fortnightly on a level 4 or so and without scalping too much etc.
What are your thoughts??
If it really knocked it back on say a level 4 would that help or are we stuck on having high couch? Even now mowing it on a level 5 now 'browns out' a lot of areas and creates heaps of clippings to be dealt with.
I once saw a contractor mow a couch lawn down to almost nothing and was shocked as it looked like he'd really buggered it, only to notice of the following week/s the grass come back lovely, green, fine and obviously a maintainable short level.
