Hello to you all! Sorry for the silence, but I was home, sick and had no internet
..
Thank you for all the answers and the infos.
The place wher I would like to put this rhodo is in half shade and pretty sheltered, part of my woodland border. We don't have very cold winters and it snows often. Never had less than -7°C.
John, my area is not exceeding in summer freshness, but count that it is at the back of a mountain and that it rains enough (all year round) that I don't need to water - almost never do. And still the drainage is perfect!
Does someone have any photo?
Thanks to you all!
