Fast Growing Screening Trees that Won't Damage a Retaining Wall.
So my new build property has an utterly blank canvas of a garden. The only problem is the developer seriously got their levels wrong and I'm stuck with a 1m double-skinned planter at the back of my garden. Also the neighbour's garden is now 6' higher than mine with only a 5' fence between us. The planter is about 0.7m to 1m wide, gets plenty of sun in the afternoon and has been topped up with good quality top-soil.
I was after suggestions for a row of trees or shrubs to put in the planter to provide some privacy - so something that is quick growing, good for screening, is pretty to look at and won't damage the retaining wall through its root system. Any suggestions? In terms of the garden's theme we wanted something that is a bit shabby chic with hint of modern... Although with a whole 4 bedroom house to decorate the garden won't be a priority for a while!
