Hydrangea leaf edges turning black
I am NOT good at gardening. I planted a bunch of plants based on what my landscaper friend recommended, though she was not able to help me plant. Now I fear everything is dying, and I don't know what to do.
My hydrangea looks awful. I don't know the name, but I know it's not Endless Summer, she told me I wouldn't have luck with that one.
Anyway, the leaves are turning black/brown at the edges. Does it need more water, or am I giving it too much water? Did I plant it wrong somehow?
Thanks for your help, I do not want to have to replant everything with new plants!
