Got This? You've got Scale..... Scale sounds and looks a lot like a plant disease, but the term actually refers to infestation by any one of more than 7,000 species of tiny sap-sucking insects. Scale insects typically adhere to the stems, branches, and sometimes the leaves of plants to feed on sap, and they have a hell-like bump appearance, which sometimes causes them to be mistaken for a fungal or bacterial disease. But the treatment of scale is much different than the treatment for plant diseases, so it is important to know the difference if you want to treat and correct the problem.
To treat scale, spray your plants, leaves top and bottom, once a week for 3-4 weeks or until the problem is gone. Spray with Eight Yard & Garden or Neem oil. This suffocates and destroys the bugs and the larvae. Several applications may be needed to completely get rid of scale.
