We have a flourishing Eucalyptus tree (dark green, long thin leaf). It was planted two years ago and now measures 3 metres high and 1. 5 metres wide. It is beautiful, but an evergreen bush immediately adjacent to it has died. We removed this in January and now the evergreen, adjacent to the place where the dead bush was removed, also has leaves turning brown. Is there anything in the Eucalyptus root/leaves which may be causing this problem?

It is possible. The jury is still out on whether they kill surrounding plants, but much of the research we saw indicated that the decomposing leaves caused the most problems. I would recommend removing any fallen leaves to see if that improves it, and if not, then it may be the whole tree is the problem.
