I want to plant a Rhododendron on the north side of my house. I know nothing about Rhododendrons.
1. There is an exhaust pipe near this area that runs from our furnace. Obviously, I won't plant directly in front of this, but what is a "safe" distance?
2. There are different varieties at my local nursery - some get really large, while others get maybe 3-4' in height. The colors that I want are the larger variety, but I'm not sure if I have enough space. Our property line is 36" from our house. If I plant the larger variety, is it feasible to prune them to keep them to size? What time of year do I prune?
3. What do I need to do to winterize?
