Topping Leyland Cypress: What You Need to Know

A landscape architect suggested topping your large Leyland cypresses to create a tall hedge. While this practice is common in Europe and generally acceptable, there's a catch: you'll need to climb a ladder every couple of years to trim the vigorous new growth that sprouts after the top is removed.

If you're comfortable with that maintenance commitment, topping can keep the hedge at a manageable height. Just be sure to make clean cuts and avoid leaving stubs that could invite disease.
