yellow leaves on holly
What is causing leaves of holly bushes to yellow and drop off?
Submitted by BHGPhotoContest

Several foliar fungal diseases can cause leaf yellowing and drop on holly. They seldom are severe enough to require fungicide sprays, but occasionally may be necessary. Dry soil conditions can also cause yellowing and leaf drop. When watering, avoid wetting the foliage, which can promote fungal diseases.
