The pruning schedule of your trees will vary based on maturity and species. When training a young tree for proper growth habits, it is recommended to perform a structural pruning, to promote a central leader, every year for 10-15 years. Following that time window, it is then recommended to perform that same structural pruning every other year, for 10 years. For fully mature trees, it is recommended that deadwood, on average, should be cleared every 3-5 years. After severe weather events, consider making an appointment for an arborist to assess for any hazardous issues that maybe hard for an untrained eye to catch.
