Camellias need some help
I have two camellias that aren't looked as healthy as normal this spring. They are Autumn Spirit, and Pink Icicle.
The autumn spirit leaves have turned partly black, while my pink icicle are yellowing. I did not put any winter protection over either this past winter, though it was generally mild. They have been in the ground 2-4 years, and generally have done well. They both are protected from winter sun.
So, I am wondering if the autumn spirit leaves are just burnt from the winter, or if something else may be going on here.
As for the pink icicle, does it just need some nutrients?
Thanks for your help.
