As the summer of 2016 comes to its end, it is surprising to see so many palms in our area showing symptoms of nutritional deficiencies. Numerous Coconut, Canary Island Date and Roebelenniis are exhibiting potassium, magnesium and manganese deficiencies respectively. Deficiencies such as these are usually caused by insufficient nutrients in the soil due to the leaching of the fertilizer by rainfall. However, they can also be caused by applying the wrong type of fertilizer to the palm. The use of a high nitrogen fertilizer, such as those made for your lawn, will cause potassium deficient in palms. Applying too much potassium to correct the problem may create a magnesium deficiency. Unfortunately, routine fertilization will not correct deficiencies in palm that suffer from an unbalance of nutrients in the soil. Specialty products must be used at precise rates. Patience is also required as it may take anywhere from 6 months to 2 years to correct such problems.
Whatever the reason for the deficiency it is important to address the problem while the weather is still warm and the palm’s roots are still functioning. This will build up reserves to sustain them through colder weather and help them overcome the deficiency.
