Fall Tree Care

by Bonnie Lee Appleton


To grow stately shade trees like this maple, check young trees for binding stakes and ties in fall.

For the past several years the retail nursery industry has promoted the idea that "Fall is for Planting." While I agree that in much of our country fall is an excellent time to plant trees and shrubs, in many cases I think the best use of fall time is "unplanting."

Unplanting? OK, I am being a little tongue in cheek. I don't mean to literally dig a plant out of the ground. What I'm talking about is undoing and correcting mistakes that were made at planting time, whether it was earlier in the year or several years ago. We have planting specifications, but I think we're long overdue for "unplanting specs."

There are four areas where more follow-up care is needed: unstaking and untying, unwrapping, unmulching and unbinding.

While you're out "unplanting," don't limit yourself to trees and shrubs in your own yard. Look around -- there are plenty of trees and shrubs at your local schools, shopping malls, public parks and a variety of other locations where even the "professionals" didn't plant correctly or haven't provided adequate "unplanting" maintenance. You may get a few funny looks from people as they pass by, but you can rescue these plants from future problems and perhaps teach a few needed lessons about tree and shrub planting and care at the same time.

Unstake and Untie

A tree needs staking at planting time only if it is unable to stand upright without one, or if it needs protection from wind or people. Assuming the tree needed staking (many don't), a year should be plenty of time. If its roots can't hold it up after that period, there's another problem involved, such as poor roots or soil conditions, that staking won't olve.

Unstaked, trees will develop trunk girth faster, and will also have the strength to keep their posture when hit by wind. Even when staked, trees should never be held rigidly in place.

Untie trees so that the material used to connect the stake to the tree doesn't "girdle" or damage the bark. Girdling restricts water and food movement in a tree and leads to a decline in growth. It might even create a weak spot above the girdle that could break off sometime later.

While you're untying, remove any labels or tags that are still attached. Plants are good at "eating" such items, again causing girdling or weak areas.

Unwrap

Remove any kind of trunk-protecting wrapping that was installed at planting time. Just as with unnecessary staking, there is unnecessary wrapping. In a few specific situations -- trunk protection at digging or shipping time or heat protection if trees are planted into paved areas during the spring or summer -- a wrap for less than a year may help. In most cases, however, wraps don't encourage trees to become established and may actually cause problems.

Bark rotting, enlargement of trunk breathing pores or "lenticels," insect and disease problems and girdling from the wrapping's method of attachment are just a few such problems revealed by my research.

If a tree's trunk has been protected with a metal, plastic or other type of guard to prevent damage caused by machinery, animal feeding or vandalism, be sure it is loose. Otherwise, once again, tree-damaging girdling may occur at the guard site.
