My hydrangeas have developed lots of black blotches on their leaves. I don't remember seeing this in previous years. they are in the front garden & my attention has been focussed on the makeover of the back garden this year, so I admit to neglecting them!Not that I've ever needed to pamper them in the past, but maybe they got too dry?

I think you have answered your own question Caroline, neglect & lack of water.
Hydrangeas (Hydra/water) require regular watering and should not be allowed to go dry, and knowing the summer we have had this year, this is the most likely thing.
Good hygene is the answer now, pick off and pick up all affected leaves and dispose of them in your rubbish bin or burn them.
Next year just give them their normal tlc and they shoud be OK.
Also; allow them to get a good winter soaking then before the weather starts warming up, give them a good thick mulch of well rotted/organic material to hold in the moisture.

Not black spot as in 'roses' it is more a physiological disorder than a disease.
A bit like us when we don't get the right vitamins, run down if you like.

Thanks, Scotia. I promise I will turn my attention to the front garden in the spring!
