Not really, but since you're already here...
This is a bit confusing, but why don't you put up a fence first so the dogs don't do their business in your garden? Or is the fence supposed to serve as a privacy screen at the same time?
I'm a bit desperate... The landlords are at odds with the tenants... no one wants to do anything... But from our point of view, it's just totally ugly and above all very unpleasant...
Because the arborvitae are completely dried out, you would see the whole misery through a "normal" fence anyway. I would therefore want to make it directly as a privacy fence.
Could be dog urine. Friends of mine also had their lawn full of holes when their puppy was still untrained.
I would tend to go for a fence here. Possibly privacy screen elements combined with a vertical garden.
The dogs can't help it; they are not walked but do all their business in the garden.
Is there a "quick" solution without having to cement anything in largely?
