I have a rhododendron which is being crowded by a Hebe next to it, bad
planning by whoever planted that border. There is space nearby to move
it to and it seems to me that Autumn would be a good time to do so. It
is only about 6 feet tall max and relatively spindly. Could I get away
with gradually digging around the roots and then moving it to a prepared
position? If so how long should I leave between cuts and what should the
watering regime be post moving? bearing in mind the ground is liable to
freeze to some extent here in Dundee.
