In Florida’s sandy soils, palms can often suffer from magnesium deficiency, which turns older fronds an unsightly yellow at their edges while the newer foliage remains green.
Magnesium deficiency can usually be diagnosed by eye. Just make sure you know the symptoms of other common palm nutrient deficiencies, such as potassium and manganese, so you can distinguish between them.
The easiest way to treat a magnesium deficiency is, in fact, to avoid it by using a palm special fertilizer that contains nitrogen, potassium and magnesium in a slow- or controlled-release form. Just be sure to read and follow all label instructions.
