What causes red tip photinias to die?
Phytophthora fungal diseases such as root and crown rot occasionally affect red tip photinia plants. These diseases typically cause the leaves to wilt, discolor and fall off of the plant. They also cause slow growth, cankers, vertical streaks and discoloration on the wood. Infected areas of the wood might exude red or black sap, and the whole plant can eventually die. Watering the plants sparingly and planting in well-drained soil are the best methods of control. If your plant has crown rot, remove the top few inches of soil around the base of the plant to the top of the roots to allow the infected area to dry out. Remove any weeds or plant tissue from around the base of the photinia.

Environment
- Photinias are large shrubs that grow well in the eastern portion of the United States. So well, in fact, they soon became one of the most popular hedge plants in the South. Unfortunately, with the overuse and close planting of red tipped photinia, disease wasnt far behind and resulted in cons…
Biology
- The main culprit among photinia bush diseases is Entomosporium mespili, the fungus that causes photinia leaf spot. Like most plant fungi, this one thrives in the cool, moist environment of the fall and spring and attacks the most vulnerable new growth that gives the shrub its name, red tipped photinia, and the disease spreads from there. The photinia fungus wont kill the plant immediatel…
Diagnosis
- The red tipped photinia disease follows a definite pattern or cycle and it is important to understand this cycle for the treatment of red tip photinia and disease eradication.
Life cycle
- The fungal spores spend the winter in fallen, infected leaves or in late emerging new growth. These spores are released into the air in late winter or early spring where they land on any nearby photinia bush. Diseases like this one tend to spread from the bottom to the top of the infected plant because the spores cant travel that far. This inability to move any great distance is also th…
Prevention
- Is there anything that can be done about red tip photinia disease? Yes, but its a matter of prevention rather than cure.
Culture
- Do not repeatedly trim endangered shrubs to encourage the new red growth. Keep trimming and shearing confined to the dormant winter months and dispose of all clippings.
Treatment
- There are chemical treatments available. Chlorothalonil, propiconazole, and myclobutanil are the effective ingredients to look for in available fungicides. Be aware, however, treatment must begin early and be repeated every 7-14 days throughout late winter and spring and again in the fall when the weather cools.
Prognosis
- Red tip photinia disease can be devastating, but with diligence and good garden housekeeping practices, the fungus can be driven from your yard.
