Cherry Laurel with yellow leaves
Hi, would appreciate some help with a 5 year old cherry laurel hedge. The leaves on 3 to 4 plants have yellow leaves and what looks like shot hole disease. The hedge is now 7ft tall and growth has never been a problem. The back of the hedge is against a brick wall and the water doesn't always reach the ground from rainfall. The end 2 plants at the other end are a healthy glossy green but grown in similar conditions.
Any advice please?
