Well, between the rain showers (and during them at times) I managed to get a few hours work done on clearing the overgrowth from the two old sheds today. The first real chance I have had since the snow put a temporary halt to the work last weekend.
Most of the work was done from the neighbour's side of the boundary wall, but here's a photo that I took from my side just as it was coming on dark this evening:
As you can see, the vast bulk of the overgrowth has now been cut away. But what's left is still going to be difficult to remove, largely because there's a mat, maybe a centimetre or two (half to one inch) thick of decayed leaves, etc, formed on top of the wall, that the ivy has sent aerial roots into, and some of the thinner branches are embedded in. I'm having to cut all of that away, inch by inch in places. But I still reckon one more good day's work (or possibly two) should see everything finally removed.
