Arbor Day Celebrates Planting And Caring For Trees

Arbor Day, an April holiday(April 28, 2017) that celebrates the planting and caring for trees, is a popular time for homeowners to add new trees to their landscapes. Before doing this, however, homeowners should consider advice from expert arborists to ensure the trees’ longevity. “Too often, consumers waste hundreds of dollars on trees that will die because they were planted too deep,” cautions Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association (TCIA).  “Proper planting is absolutely essential for the success of a transplanted tree,” says Andersen. “Using quality plants and following up with good tree care practices, such as watering, pruning and fertilizing, will not save a poorly planted tree. The most common mistake is planting the root ball too deep.” (con’t)

Andersen advises consumers to follow these planting guidelines:

Measure the height and diameter of the root ball or root spread.

Dig the hole just deep enough to allow the first structural root to be at level grade. The diameter of the hole should be two to three times the diameter of the root ball or root spread.

Set the tree on undisturbed solid ground in the center of the hole. The tree should be planted so that the root flare, the base of the tree trunk where the roots begin to “flare-out,” will be visible above grade.

Backfill with soil from the planting hole, using water to pack or settle the soil around the root ball. Do not tamp soil by stepping on it.

Mulch the planting area with 2 to 4 inches of an organic, composted mulch such as wood chips. Do not mulch up to or against the trunk. Start the mulch 6 inches away from the tree trunk.

Trees should be pruned after planting to remove broken, damaged, diseased or dead branches.

Stake and/or protect the trunk of the tree if there is a real potential for wind damage or lawn-mower injury. Remove the guy wires (string, rope, wire or other ties used with supports) when the staking is no longer needed or the tree could be injured or even killed from girdling by the wire.

Prune to develop a good branch structure once the tree has become established in its new home, usually one to three years after planting. Never remove more than 25 percent of total foliage in one year. (Depending on the tree and its condition, some arborists advocate capping pruning at an even lower percentage.)

Fertilizing is not recommended at the time of planting.
