After 3 yrs of very wet springs,this area of Ohio exprianced an outbreak of spruce canker,that affected mainly the blue spruce.I souht advice by way of my daughter{has a masters degree,in envornmental science],who directed me to the forestry department of Ohio State university.The advice I was given,was to remove the ones that had the canker,on the entire tree,which I did.The remaining 20 or so affected trees,required removal of the affected limbs.The proccedure was to use a standard pair of lopping cutters,and to dip the cutters,before each cut,in a solution of 50% bleach,and water,and afterwards,spray the affected area with this solution.All the limbs,and removed trees were burned.That was 4 yrs ago.I may be premature,but it seems to have worked.A phenonium occured,which I have never seen,the trees are sprouting new lower limbs,which I have been told ,is very rare,so maybe the story has a happy ending.
