Tree Planting and Care

After major storm, the initial impulse of property owners is generally along the lines of "let's get this mess cleaned up." But hasty decisions can often result in removing trees that could have been saved.

 

After a storm:

1. Don't try to do it all yourself.

If large limbs are broken or hanging, or if high climbing or overhead chainsaw work is needed, call a professional arborist. Arborist have the necessary equipment and knowledge.

2. Take safety precautions.

Look up and look down. Be on the alert for downed utility lines and hanging branches that are ready to fall. Stay away from any downed lines. Even fence wires can become electrified when there are fallen or broken electrical lines nearby. Don't get under broken limbs that are hanging or caught in other branches overhead. And, unless you really know what you're doing, leave chainsaw work to the professionals.

3. Remove any broken branches still attached to the tree.

If done properly, removing broken branches will minimize the risk of decay agents entering the wound. Prune smaller branches at the point where they join larger ones. Have an arborist cut large branches that are broken back to the trunk or a main limb by an arborist. For smaller branches, follow the pruning guidelines shown in the illustration so that you make clean cuts in the right places, helping the tree to recover faster.

Because of its weight a branch can tear loose during pruning, stripping the bark and creating jagged edges that invite insects and disease. That won't happen if you follow these steps:

  1. Make a partial cut from beneath several inches away from the trunk.
  2. Make a second cut from above several inches out from the first cut, to allow the limb to fall safely.
  3. Complete the job with a final cut just outside the branch collar, the raised area where the branch joins the trunk.

4. Repair torn bark.

Try not to expose any more of the cambium (greenish inner bark) than is necessary, because this fragile layer contains the tree's food and water lifelines between roots and leaves.

5. Resist the urge to over-prune.

Don't worry if the tree's appearance isn't perfect. With branches gone, your trees may look unbalanced or naked. You'll be surprised at how fast they will heal, grow new foliage, and return to their natural beauty.

6. Don't top your trees!

While storm damage may not always allow for ideal pruning cuts, professional arborists say that "topping" - cutting main branches back to stubs - is one of the worst things you can do for your trees. Stubs will tend to grow back lots of weakly-attached branches that are even more likely to break when a storm strikes.

Also, the tree will need all its resources to recover from the stress of storm damage. Topping the tree reduces the amount of foliage available to produce food and nourishment for regrowth. A topped tree that has already sustained major storm damage is more likely to die than repair itself. At best, its recovery will be slowed and it will almost never regain its original shape or beauty.
