Q: We were in Northern Ireland recently and noticed sick ash trees. Looks like their government is stepping in to control this disease.

A: At least they don’t seem to have emerald ash borer (EAB) insects in addition to the ash wilt that is spreading through the United Kingdom. EAB is killing millions of ash trees growing in the Midwest. The main source of this insect’s spread seems to be infested firewood. You see signs at every nursery and along major highways to “Burn It Where You Buy It”.
