The image above is of Evan Ogden, Senior Technician, preparing to treat an American Elm to prevent Dutch Elm Disease. The tree is located on the Washington State Capitol Campus, and to date has no symptoms of disease. Several elms were treated, including two 150-year-old American Elms in downtown Olympia. Treatments occur every three years. One of the treated elms has since fallen in a windstorm, but none of the remaining trees have exhibited any symptoms of Dutch Elm Disease since the treatments began.

Trees get stronger with age, don't they?
It seems logical to think that trees get stronger as they age, but that’s not the case. In fact they usually become more fragile as time goes on. Everything living is fighting a battle to survive. That’s just the way life is. All things degrade but, with help, life can be prolonged.

Older trees have bigger roots, right?
It's true that large trees may have big roots that hold them up (structure roots) but they do not typically grow deeper. Notice how shallow (about 18" total) the root system was on the 100 year old American Elm that failed in February 2006 (Sylvester Park, Olympia).

But the ones they live on are very small, fine roots. These delicate roots are very close to the surface .

The picture below shows how close to the surface tree roots grow.

Tree roots are easily damaged by construction equipment, poor landscaping practices, even foot traffic.

Simple things like too much watering in the summer can create conditions that invite disease.

Insects and disease can take their toll.

Significant trees need special care at times to stay healthy.

This 400-600 year old Garry Oak was damaged by junk car parts falling off a truck. Certified Arborist Ray Gleason, of Cascade Tree Experts in Olympia, and Neal Wolbert installed an experimental wrapping hoping to encourage rapid callous tissue development. The experiment worked very well with 2" of new tissue growing in one season. The wound is closing nicely and the tree will suffer no ill effects from the accident.

We can help!

Inspection and monitoring
Periodic visits checking on tree conditions can help eliminate problems before they begin.

Lab testing
Pathology reports can help diagnose root fungus and prescribe treatments.

Root/soil treatments
At times roots may need special treatments to cure or prevent problems.
It may be necessary to uncover some roots to inspect for problems. A gentle process called air-spading is used to do this.

Recommended fertilizing and appropriate “medicine” treatments can aid in the recovery and add years to the life of trees.

Foliar treatments
Insect and disease treatments may be needed to relieve stress from leaf/needle pests that attack.

Tree work like pruning, cabling and mulching can extend the life of trees.
Even though we don't offer these services, we can refer you to qualified service providers for pruning, irrigation, mulching, and landscape installation.

Care for these delicate treasures is available and not as expensive as one might think. Call us for one-stop-shopping to help your significant trees live a long and healthy life
