Concern with suffocating camelia
I have a Camellia that is espaliered on a lattice against a wall. We recently had some landscaping done that resulted in the ground level being raised by 6-8 inches.
Any suggestions on how I can prevent from suffocating the camelia? I'm assuming that if I keep the roots deep under ground that it will suffocate. Should I find some sort of semi-circle structure to keep the raised dirt bed away from the stem of the plant? If so, how wide does the semi-circle need to be?
Thank you in advance
