They are as close to natures impossibility you can deal with it seems. Huge PITA!! The evil gift that keeps on gifting.
Our problem is this started because a corner neighbor allowed his to get out of control and they bled over to us, I guess the bright side is, his problem is worse than ours overall, we just deal with it and he does not.
They are evil. We tried everything and finally hired a guy with a bulldozer to tear them all out but that was a couple years ago and they are already trying to become established again.
YUP, we try everything every late spring into summer and get them kinda under control but they come back with a vengeance every year, if we owned the property I would dig up the whole area and back fill and start over with the backyard but since we rent, not gonna go that far, our landlord should be more worried about "his" property than us, but he isn't, but that is a whole other story that I will not clog this thread with.
The GFS coming in HOT with an ultra heat dome to finish May. Hopefully it verifies. Strong offshore gradient. Storms marching up the Oregon cascades after it ends. Everything is lining up for a summer smoke layer.
But it won't since every other actually good model shows cold and troughing... which is fine with me as well.
