Question From: Brockville, Ontario, Canada
Q: Flowering crab on the inner branches toward main trunk heavy scaly growth all over the branches looks almost like the bark outer branches look healthy and blooms well How do I control
A: Jim, Pesticides are outlawed in Canada, so I cannot recommend a product. You will need to call a professional to treat your tree. Do care of it promptly as scale will weaken the tree over time and it will die. Best And Happy Yardening, Nancy
