Cut it to 3 feet so that you can work more easily with it. Do this in
the spring after the threat of frosts. (Do it now if your landlord is
really insistent; do not wait until autumn.)

It will resprout from the stump. After a year (the next spring, after
frosts), select one sprout and remove the others. Cut the stump again,
this time slanting down from about 6 inches above the saved sprout. In
three more years, you won't know it was cut. About three years after
that, you will have to cut it down again to 3 feet.
