hello and thank you in advance for your help. I have been working on a 35 year old garden in steveston-richmond- for 3 years now. It has many large 35 year old specimin trees and large rhododendrons. I have built a large koi pond and now I have to move one of the rhodos. I have this shady area where grass will not grow. Grass used to grow here, but now with 2 dogs it is the 'dead zone'. I want to create a shade garden here and I would like to move one of the old rhodos to this area. My plan is to make a raised area with lots of leaf mould and compost. I cannot find any info on when and how to transplant old rhodos. does anyone have any pointers?
