Hi --
I've been informed by a landscaper to apply Merit granules in the spring
to combat scale that is attacking my shrubs (Rhododendron and Andromeda, top
branches are turning black).
Doing a Google search shows Merit Systemic Insecticide Granules used to
control grubs in lawns.
My questions: Is Merit the right thing to apply? Where can I buy it if it
is appropriate? I went to Home Depot and they do not have it. Local nursery
does not carry it either.
TIA for any/all input. (Z6,NJ)
