My holly bushes were planted 2 years ago close to cedar trees and haven't done well and haven't grown. They lost some of their leaves.
Should Holly Plants Be Planted Close to Cedar Trees

What variety of cedar and what variety of holly? Tell me more about the condition of the holly bushes (describe the leaves, etc.)
How close are the holly bushes to the cedar tree? Are they so close that they are completely shaded? Hollies actually thrive best in full sun.
The jury seems to be out on whether cedar trees are allelopathic or not (meaning it secretes a chemical that inhibits growth of other vegetation around it). So that is a distinct possibility but I was not able to find anything too conclusive in my research.
Additionally, the roots of cedar are shallow and, as a result, might be able to out-compete other species.
I hope that helps...
