My blue hydrangeas have been turning green as the season goes on.



How do you fix that?



I finally have a good spot (shady) and good year for them (plentiful

rainfall) and now green flowers.

While i was searching some info about it on the net, i got two opposite opinions about hydrangea becoming greenish. One opinion says that it is a normal cycle of hydrangea's inherencies, while another opinion says that it's due to a bacteria called Phytoplasma. i have no idea which case you should apply to your plant.
If yours is in the latter case, they say there's no hope for plant's survival.
