I have a very large old holly at the back of my lot that has lost lower branches and I want to plant some shrubs below/as close to perimeter as roots might let me. I have a dense/spreading yew I'd love to put there - but think I read somewhere that these two are incompatible for planting in this way.. though can't find the source again.

Does anyone know if that's true? If so, any suggestions for plantings that might block views of my neighbor's yard (adjacent to it)?

Thanks so much!
