MAINTENANCE NEEDS: High Maintenance. Water regularly, do not let the soil dry out. Fertilize in spring or summer to encourage bloom, but do not fertilize in fall- it will encourage tender growth. Mulch planted area. Prune after flowering. Drip irrigation will help prevent leaf spot. Insects can be a serious problem, as well as powdery mildew, dieback, and sooty mold.
