Once the palm has recovered, our semi-annual maintenance program will assure that the palm does not regress and become deficient again. Palms before treatment and again approximately one year after initial treatment. Note the older, lower growth that is still frizzled. Remember that the treatment does not affect existing fronds. Note bottom fronds that are still frizzled.
Treatment only affects new growth.
Mg deficiency is not as serious a problem as Mn deficiency, though it still should not be left untreated. Mg deficiency appears as a premature yellowing of the fronds, especially the new fronds. It is normal in some palms to have the lower growth to discolor slightly. This is a sign that the palms need to be trimmed. This organism causes a gradual decline in palms.
