Cotoneaster

[pidgeon1]

Well established Cotoneaster on steep bank now has grass growing through the plant, is there a weedkiller I can use to kill the grass but not the plant.

Not able to weed by hand to remove the grass.

Thanks for any suggestions.

 

[Why Not Indeed]

I've often wondered this, plenty of places where I don't want grass but don't want to kill everything. There seem to be plenty of weedkillers that do the opposite.
