To start with palms should be pruned with the Tree Climbers/Swiss Bicycles/The Bands to avoid spiking them. Spiking causes wounds and entry points for all sort of pathogens and insects which can lead to the failure of the tree. Fronds should be trimmed, paper should be cleaned out, seed pods and nuts should be removed. Palms should be pruned with the fronds coming out the base of the tree at 45 degrees and no higher. Taking the fronds higher over time causes the tree to lack enough leaf surface area for proper photosynthesis (food production from light) and can cause penceling (tree tapering). In this state of loss of food production the tree can become stressed leaving it vulnerable to pathogens which combined with penciling can lead to tree failure. Coconut palms should be trimmed 2-3 times per year in residential settings and 3-4 times per year in commercial areas in relation to how quickly they grow. Click on photos below to enlarge.
