Hydrangea Kardinal Violet starting to lose colour.
Please excuse my second post on the same subject but my original post has an odd title due to laptop problem and I can't see how to change it but will try to delete it.
I have a Hydrangea Kardinal Violet planted in early June 2015 and it is starting to lose its colour. As a novice I am unsure if this is natural at this time of year or whether it needs a hydrangea colourant treatments(I used Vitax about 6 weeks ago). Any advice from our readers would be appreciated.
