Juniper : Magnesium deficiency
(revision date: 4/23/2014)


Biology
Magnesium (Mg) deficiency is a result of improper nutrition. A juniper lacking sufficient magnesium develops yellowing or dead foliage in the center and grows slowly. Older tissues are affected first. Magnesium deficiency may resemble damage caused by Phomopsis twig blight.
Management Options

Non-Chemical Management
  • Apply Epsom salts (magnesium sulfate) either to the soil (1 cup per 100 square feet) or as a foliar fertilizer (5 ounces per gallon of water).
  • Switch to a fertilizer containing magnesium.
  • Addition of dolomite lime to the soil may help, but is not an immediate solution.
Select non-chemical management options as your first choice!
