a you can prune healthy yews taxus spp back quite severely with no problem you can easily reduce their size by one half to three quarters such severe pruning is best done in early spring so they have spring and summer to recover they will respond by throwing up a lot of new growth
Prune in late winter or early spring, while the plant is still dormant. Remove any dead or damaged wood, do a little shaping if necessary, and take out some of the interior stems to improve air circulation. Every 2 or 3 years remove about one third of the old branches to stimulate new, fresh growth.
