Anne's Response:

Leyland Cypress have been affected by drought during the past year. With as many plants as you have I suggest you have a certified arborist diagnose the problem your plants have and then recommend a treatment plan to save them. It is not unusual to have Leyland Cypress decline after about 10 years in the ground. They prefer the temperate, moist climate of England to the heat and smog of the urban south.
