Proper nutrition keeps palms healthy

by | Apr 12, 2021 | General Environmental

The beginning of the growing season is often a time when palm nutrient deficiencies show up. Palms start growing quickly this time of year which depletes nutrient reserves in the soil from the last nutrient application. The most common nutritional deficiencies of palms are nitrogen (N), potassium (K), magnesium (Mg) and manganese (Mn). Other essential nutrients such as boron (B), calcium (Ca), copper (Cu) and zinc (Zn) are occasionally found to be deficient if they are not present in the fertilizers applied, but these deficiencies are not very common in the landscape.

Nutrient deficiencies can be caused by insufficient nutrients in the soil, a nutrient imbalance, poor soil aeration, a high soil pH and an excessive planting depth. The agronomy team is currently in process of making nutrient applications to all shrubs and palms, and is applying a heavier feeding to those showing signs of deficiencies. The IPM (integrated pest management) team is also on the lookout for deficiencies and will supplement on an individual basis, as needed.
If we observe wide-spread palm nutrient deficiencies on any property that we have maintained for over a year, we will inform the property manager and submit a proposal for an additional application to all palms throughout the property.
