Significant Tree Restoration
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, just like humans and animals. Everything 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 always grow deep roots. Notice how shallow the root system was (about 18" total) on this 100 year old American Elm that failed in a freak windstorm in February 2006 (Sylvester Park, Olympia).
Large anchor roots hold trees up, but the ones they live on are very small, fine (feeder) roots. These delicate roots are very close to the surface The picture below shows how shallow the fine roots on this ancient specimen were.
Tree roots are easily damaged by construction equipment, poor landscaping practices, even foot traffic. Visit this link for information about how trees are damaged during construction, and how to avoid it.
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.
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.
Notice how shallow the fine roots are. These are the roots that transport water and nutrients through the tree. Recommended SuperRoots bio-fertilizing and appropriate fungicide treatments (medicine for disease) can aid in the recovery and add years to the life of trees.
