Q.camellias
I planted new plants in November. They had many blooms and flowered even after frost. I moved them to a shady area by my north facing front entryway. One of the plants has leaves that are staying green but are getting brittle and are dying. What’s wrong? Thanks.
Camellia's that are in containers will need more protection against the cold temperatures.
The roots are more susceptible to freezing in containers then if they were planted in the ground.
Do the branches break and snap?
Scratch the bark--if you see green underneath, it is still alive.
Prune away the dead material and wait and see.
