A magnesium deficiency , although never fateful to a palm plant , can induce the ontogeny of unsightly yellow bands on the frond .

A magnesium lack first seem on the oldest medallion leaves . Leaves develop broad yellow bands along folio margins while the central fortune of leaves stays fleeceable . Younger leaves have progressively wider landing strip of greenish foliage tissue . Sometimes a atomic number 19 deficiency occurs at the same time . A atomic number 19 deficiency is indicate by necrosis on the tips of the Old leave-taking , while the magnesium lack will hale symptoms on mid - canopy leaves . leave of absence between the two deficiency zone will have both symptoms in different portions of the leaf .

Magnesium in the soil of container - grown palms can be depleted within several months following supplement lotion .
About Magnesium Sulfate
Mg sulfate is a contour of supplemental Mg recognized most commonly as Epsom salts .
