The tree was put in the ground about 6 years ago. For the most part, I have let it grow with no interference; only trimming extra long branches. I lost a middle branch growing upwards in year 2 due to freezing weather. I would like it to eventually grow into a canopy over the grill, heat pump, and patio.
Do I let the tree grow as it does and wait until the upper canopy forms, before trimming the lower branches, or do I trim the lower branches now to encourage upwards growth?
