What time of year is it best to prune Japanese Yews. Ours are out of control and I'd like to knock them back to a manageable size. I don't want to damage them.

Year round trimming of dead or diseased branches.
Shaping the shrub should began in early summer after the new spring growth is in and it has turned dark green.
