@bondjenna20bP3ha-ic Welcome.I am suprised you have found just the one piece. Not sure it is something you will get rid of. You could type in Mares tail at the top there are lots of threads and perhaps some ideas?
I have worked as a Gardener for 24 years. My latest garden is a new build garden on heavy clay.
