I am considering buying some Photinia SERR. "Red Robin" hedging plants.
I noticed in the nursery some of the leaves have black spots. Is this a fungus or disease?
red robin are quite easy to grow, imoI had 3 in my garden in a heavy clay soil and they grew well. That is the problem they do take over depending on the size of your garden.
Always check any plant for desease and state of roots ball before buying and by good stock only
