Yews (foundation) - topiary candidates?
I have some yews planted around my house - quite a few of them, all the same globular, flat-topped shape. The house was built in the 1960s and I would hazard a guess that they were planted quite a long time ago. Questions - can I move them, if so when is the best time? Does anyone have experience of clipping mature specimens like this into topiary - I am thinking I can vary the shapes and perhaps create a couple of cubes rather than blobs. Is it too late for spirals?
