Hi - Can anyone tell me what these raised white spots on my hydrangea are?
Many thanks in advance!
Here is a link that might be useful: spots on hydrangea
Doesn't look like disease or insect damage. Instead, something was perhaps sprayed on it? In any event, very unlikely to get worse.
Thanks Jean. Should I remove affected leaves or prune a bit as usual in the fall? BTW, unfortunately, I couldn't load the image you posted even when i copy-pasted the url. what was it?
I'd let things be. The leaves will soon drop of their own accord because it's time. No point in removing leaves that aren't diseased.
