Eucalyptus and Ginkgo

10 or 12 years ago a man in Redditch market sold lots of plants including eucalyptuses & ginkgos for £1.99. He warned that the eucalyptus would shoot up but could be heavily cut back. Somehow I took my eye off the ball and now my eucalyptus is as tall as a house. The ginkgo is about 5' tall.
