Leyland Cypress – Dying in Shade
Q: We have a row of Leyland Cypress that is starting to die off one at a time. They are about 10 years old and we have lost two on the left side of the row. I thought the first one died due to being shaded too much by the maple in front of it.
A: I think shade and close planting is the problem…leading to cercospora decline.
Leyland cypress loves full sunshine. In shade, it thins considerably. If the shadey area is also prone to dampness, fungal diseases get started and the plant begins to look ugly very quickly.
If you need screening, try a ‘Bright ‘n’ Tight’ cherrylaurel.
