I have white hydrangeas which are beautiful but have noticed today some are getting brown on the flowers – what causes this please?

Browning of Hydrangeas leaves could be as a result of hot dry air. Distinctive brown spots are however probably caused by Botrytis caused by allowing water to stay on the leaves for any length of time.
