|i purchased a blue hydranger in july, it's still potted and has it's blooms, but the blue has turned to green. what to do ???
|The blue color is fading because the flowers are aging. There's not much you can do to keep the flowers from aging. If you find them unattractive, you can prune them off your hydrangea, along with some of the flower stem. As your plant matures and develops a more extensive root system, it will be able to hold those flowers for a longer period of time before they begin to show signs of aging. Best wishes with your hydrangea.
