Hi. I have a very large azalea in front of my house. It’s actually 2 shrubs that have grown closely together and appear as one and are greater than 6 ft tall and wide. They are over 90 years old and I haven’t touched them in 30 years. (My bad) They still flower beautifully in the spring. They are in desperate need of pruning but I’m afraid if I do they may die. My landscaper recommended that I just take them out as there are a lot of dead branches throughout the inner parts of the shrub that may not come back. I’m very torn about what to do. Any advice would be greatly appreciated. Thanks!
