Hello everybody. Can anyone tell me what the marks on the leaves of my young hydrangea macrophylla are/mean? They look scorched. Thank you.
The purple markings together with the scorced edges - looks like the sign of potassium shortage.
Í think the leaves have been battered by wind, rain and cold weather in general. To me this doesn't look like a shortage of potassium.
My hydrangea has some similar leaf damage - I'm 99.9% certain it was caused by the frost when the leaf buds were opening.
Dovefromabove, everyone: mine has continued to get worse. The foliage has grown nicely bushy and is standing strongly but the top-most leaves are all like in the picture below. I'm wondering if I'm not going to be able to do the right thing with it to improve whatever this problem is. Everything else in the same bed is growing really well and only the hydrangea has leaves like this. Not sure what I should attempt next or just leave it to see how flowering goes. Other than this eaten away sort of damage to the leaves the plant overall looks remarkably healthy and strong. I wonder if I ought to be spraying it with something.
