We are looking to screen our neighbor’s two storey house as they can see into our yard and home. The problem is due to the size and location of our block we would need to plant a hedge behind a retaining wall.
The garden bed behind is about 2 feet deep by 2 feet wide (fence to wall) and several feet long. As it’s along the fence line the back half is mostly shaded. We’ve several different plants growing already but nothing that can shield us from the neighbor to that height.
Was thinking maybe the Italian cypress glauca (pencil pine)?? WDYT? Can anyone suggest another evergreen that can grow tall in our Canberra clay but not have a root system that will be invasive and cause the retaining wall to crumble? Any help would be highly appreciated to us novices!
