When landscape philosophies collide
What do you do when a "let nature burgeon" approach from one neighbor affects "ordered designs" by another==and it is costly in terms of time/money to deal with it?
To preface, a common gravel alleyway historically runs behind houses in my neighborhood and ended past mine. I have a hedge row that follows it and past a point, it was allowed to grass over and no cars ever used that.
A developer drastically altered the landscape on the other side of the alley so that it is very steep and there are now houses where there was once a hill meadow. The neighbors at the end of the gravel area always liked the woodsy look and are non-maintenance sorts for the rear of their property anyway. They want to hide the view of the development. These naturalists would throw their leaves and branches on the other side of the alley until the developer got on their case when a new house was being built there. The graveled area alley access people blocked off the end of the alley with a mound of gravel and dirt, so the walkway from the grassed alley to the gravelled area is cut off unless one veers into the steep dropoff. And, all their leaves, sticks, branches are now heaped into the alleyway as well.
So, the alley doesn't actually belong to the "leafy compost makers" and they aren't maintaining it. Growing in this heap and around it are Canadian thistle, poke, junk trees like ailanthus and wild blackberries. Guess which things are invading *my* yard in a big way. I'm trying to landscape and have a roserie and butterfly garden along the alley and I'm constantly being plagued with this invasive stuff.
Problem is, for legal standing, they are not on my property line due to the weird lot layout by the developer. Everyone else around me uses landscaping/gardening services except for me and no one is touching this problem with a ten foot pole. The owners of the little triangle between me and the hump avoid it. No one is spraying/cutting to kill the thistle/brambles either.
There is no homeowner association that covers the alley dwellers as these are older houses. Apparently the city doesn't want to get involved code wise.
What does one do in landscape design when situations like this come up? Just figure the cost of fighting invasives from neighbors as a sunk cost?
