Look up, down, all around…how are your trees faring?

Trees provide many benefits but, like us, they may sustain injuries, become ill, or just get old and creaky. It’s a good idea to walk through your yard occasionally and take a peek at your trees from time to time to assess their condition.

Here’s a quick three-step process to inspect trees in your yard – think “up, down, and all around.”

  1. Look UP to the crown. Check for dead or hanging branches, limbs that lack bark, or show no signs of life. Dead or hanging branches may fall at any time, especially during winter winds. Do you see lots of fine twigs that have living buds? If not, that may indicate the entire tree is beginning to decline.
  2. Look DOWN to the roots. Visually inspect the root zone and the trunk flare (also called the root collar) just above the roots for damage. Look for peeling, cracking, or loose bark on the roots and lower trunk. If you see mushrooms growing out of the trunk or along the roots, these can be signs that a tree’s roots are decaying. Be alert to mounding or cracked soil that you haven’t noticed before, especially after heavy winds. This can be an indication that roots are broken and are not supporting the tree properly. If you see newly mounded or cracked soil, call a certified arborist as soon as possible to assess the tree for structural root damage.
  3. Look ALL AROUND the trunk. Inspect the trunk for wounds, cracks, or splits in the trunk, particularly where branches are attached. This could indicate decay or the potential for branches to fail. Look for decay pockets; if they extend over 1/3 the diameter of the trunk of the tree, that may indicate significant internal decay that compromises the strength of the trunk. Check for a lean greater than 40 percent, which may overbalance the tree if the root system is weak or damaged.

If this quick inspection of your trees raises questions about tree health or safety, contact a certified arborist to conduct a full inspection. This will give you peace of mind about whether your tree is okay, needs special care, or is approaching the end of its life.

If you’d like to learn more about assessing your trees, check out “How to Recognize and Prevent Tree Hazards” from the Pacific Northwest Chapter of the International Society of Arboriculture. The brochure contains explanations about warning signs to look for in trees along with great photos that illustrate those signs. You may also contact DNR’s Urban and Community Forestry Program for more information about caring for your trees properly to keep them healthy and safe.
