Mon, Peter and I spent another afternoon rooting - or de-rooting - and we are winning, but only slowly. This is how bad it is at this point:
We have now cleared about 2/3 of the bed, but it's impossible to tell if it is going to get better or stay as repulsive as it has been since the midpoint. Keep your fingers crossed that it's going to get better. It's so frustrating! And I have no idea what will be below the bed - there is a layer of thick black plastic which we can't yet move and we don't know if there's going to be soil or paving beneath it. Either way it's going to be better than what was there before.
