Q.Roots of Silver Dollar Eucalyptus
We planted a Silver Dollar Eucalyptus four years ago, and it is really beautiful. However, we would like to know about the root structure. Are they shallow or deep? The tree is near our drain field and we are having problems. Is it likely to be the root structure? Before we cut the tree down, I am hoping to find a solution. The tree is spectacular. It is one of the smaller silver dollars, about 25 to 30 feet.

Eucalyptus roots tend to be shallow compared to other trees, going down about 6-10 feet normally. They are very water hungry and if they cannot find a way to get enough water in the soil, may invade pipes. You can try giving it extra waterings, to keep it from seeking out water from the pipes or redirect runoff water to the tree for teh same effect.
