Block wall help
I have a south facing block wall that I need help with. The neighbors behind me have a vegetable garden that touches the wall and with all the watering they do it is causing staining on my side. Talking to them has done nothing. It's really ugly to look at so I'm wondering what would be the best solution.
I have a pool so I would need something that isn't messy. I already have two pygmy date palms, some deer grass & yellow bells near the pool, while the hide some of the wall-it's not enough.
A landscaper I talked to said to plant Orange Jubilee and while that is pretty and can tolerate the heat of the wall, I'm afraid I'd have to line the entire wall with them and not sure if I would like the look.
Is there something to apply to the wall without painting it to stop this?
Any other ideas?
