What is the Best Time of Year to Trim Trees in Arizona?

“When should we schedule trimming in Arizona?” is a frequently asked question. Winter is an excellent time to trim non-native deciduous trees and evergreens, especially pines, which tend to drip sap if trimmed during spring or summer. Most Arizona trees can be trimmed throughout the year if correct procedures are followed, but the best time to trim depends on the species and the objective. for example fast growing desert trees near buildings and walkways should be trimmed sometime after spring growth flush and before the Arizona Monsoon season to control size and spread without over pruning. Palms should be trimmed after the fruiting stalk appears, to minimize litter, and date palms should be trimmed in May or June before the heavy fruit forms. You should build all these and other considerations into your tree management plan so you don’t have to worry about it once it is in place.     

Bear in mind that pruning is a science, and mistakes are long-lasting and costly. Over pruning, poor selection, and improper cuts will shorten a tree’s life, reduce its aesthetic and environmental value, and ultimately turn it into a liability instead of an asset. It is important to consult with a knowledgeable arborist with experience and good judgment to make sure that the right things are done in the right order, at the right time, within your budget. Whether you as an individual homeowner or member of a homeowner association truly receive the assistance of all that good judgment depends thoroughly on the men in the trees who are performing the work. A tree trimmer without the education, skill, experience, and commitment to excellence that is needed, can, and most certainly will, cause long-lasting damage to your trees. The men/women in the trees need to be experts. It takes extensive, current education, training, and experience to develop skill in pruning trees. If a person has not made that investment, you would be well advised not to let them near your trees with a chain saw.  

Trees are the oldest living entities on earth, and each has a possible value of thousands of dollars. Beautiful trees make a character more desirable and valuable in many ways. We recommend spraying Arizona olive trees to control fruit and pollen January by March–the earlier the better to avoid pollen that can be so troublesome to allergy sufferers.
