What is wrong with my red tip photinias?
Red tip photinias are very susceptible to Entomosporium leaf spot , a fungal disease that can cause severe damage. Disease spores are spread by wind or splashing water, so space plants to improve air circulation and promote rapid drying of leaf surfaces. When irrigating, avoid wetting the foliage and irrigate in midday to promote rapid drying. Remove fallen diseased leaves. Do not water or fertilize more than is necessary to avoid promoting excessive new growth. Minimize summer pruning which encourages new growth. A fungicide such as Daconil or Funginex can be sprayed starting when new growth begins in the spring with additional applications at 10 day intervals until mid-June. Severely diseased plants should be removed and replaced with a different plant that is not susceptible to leaf spot.
