Diseased Magnolias In the Neighborhood . . .

How many neighbors have wondered what those white spots are all over some of the magnolia trees in the neighborhood? I have one sick magnolia in my very own back yard.

I visited a local garden center two summers ago and applied the treatment they advised, but saw no results. A recent post to GardenWeb.com came up with a likely culprit: magnolia scale, or Neolecanium cornuparvum (Thro). Read all about it and find treatment options here.
