I am a beginner, but I can vouch for NVC's effectiveness. It helped me deal with my neighbor in a more effective way.
I was in my back yard, a relatively large space (by Portland standards - it's a quarter acre) that I'm reclaiming from the Himalayan blackberries, perennial morning glory and sweet autumn clematis, all vining, super persistent and invasive plants in this climate. I have a six foot chain link fence around most of my property's back yard, and my neighbor on the south side came up to me to talk about the vines growing on the fence (just a few at that point, I will point out).
He said, "What we need to do is hire some guys to dig this out completely on both sides, and then put down concrete, two feet of concrete on each side." I was stunned. Luckily, I was so stunned, I didn't respond right away. I tried to remember some NVC advice. . .
So I said "What I hear you saying is that you would like a permanent solution to this problem, something that is once and done."
"Yes," he said. And right there, at least we were still communicating!
I suggested that if we install and encourage plants that we like, we can overcome the invasive vines without resorting to concrete. I pointed out the thornless raspberries and passionfruit vines I'd planted there, also the jostaberries and the hydrangeas back in the shady area by the western fence. I commiserated that it is frustrating to have to remove the invasives over and over again, but I shared that it seems to me they are getting less vigorous with time.
And henceforth, I've tried to weed that southern fence, starting in the far back corner, first, when I have a little time to garden.
One PNW gardening tip: I've found I can throw the morning glory vines into the chicken pen and they will die and dry up there. Once dry, they are a fine addition to my
compost system. I'm lucky enough to have a big double rotating barrel that an elderly neighbor sold to me for cheap, so I get good breakdown.
