Hello, Nihal. It sounds like normal bloom color progression. My blooms turned green about 1-2 weeks ago. Hydrangea blooms tend to change colors as they age. It is very common for them to bloom pink and then turn green (with some speckles of pink). The specific sequence of color changes for blooms depends on the variety that you are growing. However, I would have expected that you noticed this bloom color change in previous years since they always change (although not necessarily on the same month as in previous years).

Roses loosing their leaves may signal a watering issue or blackspot.
