How often should the tree be pruned?
Most of the trees planted through our program are pruned on this schedule: 18 months after planting and 3 years after planting. We recommend 5 years after as well. Fast growers, which include acacia, elm, locust and peppermint willow (Agonis spp.), are pruned at 12 months instead of 18 months. After the 5 year anniversary, prune on a regular basis as needed, depending on rate of growth, environmental and other factors. Just don t delay for 10 years then prune a bunch off the tree to make up for it. Think of tree care as dental care, a little effort and expenditure on a regular basis to avoid an expensive and painful procedure later.
