When you buy eucalyptus watch out which kind you get. There is one kind from Australia that grows really fast but unfortunately its roots look for water and it this country that means you water pipes and sewage. I had one of those trees in the front of my house. I had it cut down 17 years ago, but still my toilets are regularly blocked and when we open the manholes whole bunches of roots come out which had totally blocked the system. This even after having been cleaned out previously and after so many years. So my advice, watch out.
