I have a number of global taxus shrubs that are about 35 years old. Presently, they are about 2.5 ft high and 3.5 ft in width. Is there a method to get these dimensions smaller without killing or replacing these plants? Thanks!
Yews ( Taxus spp.) are fantastic evergreen plants. They are slow growing and will respond well to pruning. Generally they have 2 bursts of growth per year. New growth will develop on old wood which means they will tolerate heavy pruning. Spring is a good time to prune. Be careful not to prune or shear after August as you don’t want your plants putting on new growth as fall and cold weather approach .
Please see this Michigan State University article about pruning evergreen which gives a very good description of pruning:
