Have a 2 year old garden with a new build house.
Was a total mess on moving in with poor soil and scattered grass seed.
Got it looking fairly well last summer with plenty of tlc, overseeding, feeding etc.

Now this year I've a lot of coarse field/meadow type grass all over the garden with seed stalks growing back very quickly after cutting.


Any advice on what to do here or how to get rid of it?
I am right next to fields and farmland so not surprising.
