| Cherry Laurels are planted along the front of our house as foundation hedge. We trim them to stay about 3.5 feet high. They are established plants, about 12 years old.
In late July the leaves on one of the plants in the middle of the row started to turn brown and then died. I was so surprised, as Cherry Laurels are very hardy in our area. Then the one next to it started to die, and then the one on the other side of the original one to die started the same death march. We cut them out, intending to replace them, but now the next one in the row is beginning to die in the same way --- leaves start to turn kind of silvery green, with some darkened spots, then totally brown and very dead.
It has not been particularly dry here this year, and they are established plants. Any ideas what this is? |

| They can get Fire Blight. Did the leaves hang onto the plant and the stem turned dark? It is a bacterial disease spread with rain. There is a spray, one of the -mycins (terramycin?). Works well. |

| Prunus laurocerasus, Ken. Not particularly short-lived. |

| Cherry laurels are susceptible to root rot diseases caused by soil borne fungi. That's what I would suspect. |

| As a member of the Prunus clan, laurels of all variety are prone to a whole host of disease issues. In addition to the various root rots Dorie refers to, there are assorted fungal stem cankers that can cause branch dieback or even plant death. Also bacterial and fungal leaf spots that can be very disfiguring and the fire blight previously mentioned. While I agree that laurels can provide an excellent evergreen backdrop as a foundation planting or as privacy screening/hedging, if you are having issues with this plant, perhaps now IS a good time to consider an alternate, less disease-prone solution. |
