I just happened to find more "before" pics of my project in an old thread I started a year ago. I spent 45 minutes today digging up more Knotweeds. It starts like I always do, I intend to just go outside and do some "forest bathing", then I pull up a couple shoots of knotweed, then I find more, then I end up digging up large Knotweed roots. I've gotten to know what they're like. Knotweed roots tend to be brittle and I've learned the way they sound when they break, a kind of sharp "crack" sound.
These "before" pics are more recent because the new fence is up, May 2015.
Some recent pics:
This one I took to add to my sunlight inventory. Morning around 8:30am.
