We just bought a home with a huge rhododendron bush that has to be 15 ft tall and the entire expanse of the house. We have cut it back from the house, but I want to bring the top down to about 6 ft. How is the best way to go about this without hurting the bush?

I would not take off more than a third of its growth at any one given time, unless absolutely necessary. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/shrubs/rhododendron/pruning-rhododendrons.htm
