Potassium Deficiency
Maintenance Fertilization Spikes Contains Nitrogen plus soluble
Manganese, Magnesium, Potassium, Iron the use of proprietary
binders to safely release the nutrients to the feeder roots of your
Palms right where they are most effective. Each spike provides exact
measured amounts of these fertilizers so palms can be properly
fertilized by using the correct number of spikes according to tree size.

Palm Manganese Spikes depending on the size of trunk and severity
of deficiency. Normal response is from 1 to 3 months. Treatments
may be made anytime the deficiency is observed.
Manganese Deficiency
Symptoms: the new emerging leaves, causing yellowing and necrosis
between the veins and a reduction in leaf size. As deficiency becomes
severe, the new leaves wither and have a "frizzled" look. If not
promptly treated, Manganese deficiency is often fatal to the palm.
Manganese deficiency can affect most species of palms.
Palm Magnesium Spikes , depending on the size of the trunk and the
severity of the deficiency. Recovery can take several months.
Treatments may be made anytime the deficiency is observed.
Magnesium Deficiency Symptoms the older leaves, causing them to
yellow at the edges while the center band stays green. In severe
cases leaflet tips also become necrotic. Magnesium deficiency can
affect most species of palms.

Palm Tree Potassium Spikes depending on size of trunk and severity
of the deficiency. Complete recovery can take a year or longer.
Treatments may be made anytime the deficiency is observed.
Potassium Deficiency Causes yellow, orange or brown flecks and
necrotic margins of older leaves. Withering begins on these older
leaves first. From a distance these leaves often appear brown or
orange in color. If deficiency is severe enough, new shoots will
eventually be affected. If unattended, the palm may die. Curing the
potassium deficiency can lead to magnesium deficiency. To balance,
potassium and magnesium should be applied together.



Do not lime the soil unless the soil pH is less than 5.0. When liming, use dolomitic limestone.
(Recommendation when the soil pH is less than 5.0)
Trees are sensitive to magnesium deficiency, therefore follow the magnesium fertilizer recommendation when
given. Magnesium may be included in an applied fertilizer formulation. (Recommendation when soil test
magnesium is low)
Caution: Trees are sensitive to “over-fertilization,” particularly for phosphorus. Care is advised when
surrounding turf or ornamental plants are being fertilized, by keeping applied turf and ornamental fertilizer at
least 30 feet from the base of the tree. Do not apply fertilizer to a newly planted tree until new growth
begins. Do not apply fertilizer during the winter months. Do not place the fertilizer in a band around the tree,
but evenly distribute over the application area.
Evenly apply over a 10 by 10 foot area around the tree, 1.5 lbs 12-4-12 or comparable fertilizer, preferably a
slow-release formulation. In the southern half of the state, repeat the fertilizer application 3 or 4 times during
the growing season (April to September). For trees planted in the Piedmont, reduce the application times to
3, cut the fertilizer rate in half for clay soils, and do not apply fertilizer after August 1. (Recommendation
when phosphorus and potassium soil tests are L-L, L-M, M-L, M-M)
