My pool has finally been repaired and retiled and the brick wall rendered wall. My neighbours live in a two storied house just over the wall, so I would like to screen the wall for noise reduction and privacy. I have found some trough pots that are either cream and 340mm (13") across or black and 500mm (20") across. I think the black pots would be better as the bigger size would allow for taller plants, but am not sure if the colour is right. Any help will be appreciated.
