I am having problems with this hedge loosing leaves and looking very thin in the middle. There are a lot of leaves on the ground that have fallen off. Some of the leaves are yellow and some have black spots on them. There is no new growth on any of the branches. Can you HELP please!!!!!
Thank you

Photinia is subject to black spot, especially if the leaves are wet overnight. Try to water the soil rather than the foliage (knowing that you can't control the rainfall) to avoid the spread of the disease. You can prune your plants in early spring, just as new growth begins. This will remove the old spotted leaves and, since the beauty of this shrub is in the bright red new growth, will encourage lots of healthy new growth. A fungicide can help protect the new leaves but will need to be applied just as the new leaves emerge and repeated every 10-14 days until the leaves are fully mature. You can use Daconil, Bayleton, Banner or Funginex according to label directions. Best wishes with your photinias!
