Question: 215-5201
We have white cotton masses under the needles on our hemlocks. What can I use to get rid of them? Can I throw the pruned branches nearby? Bob, East Lyme, CT

Mort's Answer:
Do not throw the branches in the area. They are best carried away to the municipal dump. Adelgid woolly aphids are reaching epidemic proportions in New England. Spray with a combination of malathion and diazonin. Follow directions on the labels. The woolly aphid creates galls and can kill the trees eventually.
