Thanks for the warm welcome. I hope I can contribute more in future.
I will get some photos shortly and post them. That will help in my question below, but I will put the question up anyway.
So it sounds like the Couch is pretty robust. Could I plan to reduce the height until I may scalp it in a few areas of my lawn where there is some bumps and then top dress it with some sand say early January? Is it bad to top dress in the peak heat of summer?
Thanks for you help!
