Emerald Ash Borer Prevention - Spring 2014

Mission Statement


New Heights Plant Health Care, LLC is locally owned, operated and provides total tree care for the Colorado Front Range.  Our employees are all certified applicators.


We carry the background of workers in the tree care industry with over 15 years experience in tree removal, tree pruning (trimming), and maintenance of local area trees.
Although our focus is not traditional tree maintenance such as removal, pruning, or stump grinding, we  find the knowledge of area trees to be a valuable resource.


We believe in maintaining healthy trees and tree growth through deep root feedings and preventative treatments, so that trees do not become dangerous and on the slate for removal.


New Heights strives to stay above industry standards by using the latest technologies and environmentally friendly plant health applications.

Poor and Compacted Soils

Colorado's soils are notoriously low in nitrogen, phosphorus, and potassium. In addition, soil compaction and competing root systems in urban environments decrease the amount of minerals and water the trees' roots can obtain.


Due to these factors TREE FERTILIZING, SOIL AMENDMENT, and DEEP ROOT FEEDING are important proactive steps to increase the availability of minerals, water, oxygen, as well as loosen compacted soil around the tree. In turn, overall vigor can return and enable the tree to use its own defenses against insects and disease.


Insect Ability to Overwinter in Warmer City Environments

Some insects that would normally die during winter freezes are now able to survive the winter  months by  sheltering in warmer urban areas. This survival strategy allows the insects to grow in both population and habitat area.


Non-Native Insect and Disease Infestations

Due to tree concentration, insect and disease transference rates are high in urban environments. Lack of natural predators and the planting of non-native species have led to the introduction of invasive species and maladaptive growth.


All of these stressors predispose urban trees to a greater risk of insect and disease infestation. New Heights Plant Health Care, LLC carries a large selection of DISEASE AND INSECT SPECIFIC MICRO INJECTIONS, as well as traditional TREE SPRAY.


Poor Drainage and Restricted Growth Areas Due to Initial Planting

Urban planting often results in less than optimal placement of trees. Cramped root areas and poor water drainage often results in fungal growths which weaken the tree and make it a good candidate for infestation.


 Many insects carry out a symbiotic relationship with fungoid when attacking a tree. MICRO-INJECTED FUNGICIDES can provide systemic relief for the tree and lessen the chance of attack from insects and disease.





Common Questions

  • Yes, Emerald Ash borer was found in Boulder, CO on September 23, 2013. This finding is the first in Colorado and the furthest West that the bug has been spotted.


    Boulder County and surrounding areas are now under quarantine from the Colorado Department of Agriculture. It is estimated that the bug has been here for 2-3 years prior to detection.


    Emerald Ash Borer was discovered in twenty-two trees at the CU campus. The infestation zone extends north (see lower map) to 30th and Iris where one dead and five infested ash trees were found in a condominium complex .


  • Products are applied via a micro-injection system starting in May/June through approximately October. This involves drilling a small hole into the base of the tree and inserting a plug through which the application is injected. All said product is inserted into the tree and the plug prevents any back or out flow.


    Deep root feeding your tree is recommended, though not necessay, to increase your trees natural defenses and encourage movement of EAB application throughout.Drawing of leafed out tree and extensive root system


    Applications are not as effective during drought conditions. Drought stricken trees conserve water at their core and do not provide adequate dispersement  throughout tree.

  • Ash trees in Emerald Ash Borer infested areas will generally die and need to be removed within 2-4 years of bug presence, if not treated.


    Things to consider:

    Old, damaged, or unhealthy trees may not respond well to treatment , thus removal and/ or replacement of the tree may be a better option


    Areas with high density or ash only trees, aesthetically valued trees, and trees contributing to property value that are in average to good health can be saved if treated promptly and on schedule.


  • Quick Jet injector injecting tree trunkTREE-age™, emamectin benzoate,  has been shown to be effective in preventing tree death from Emerald Ash Borer. Treated trees have 99% fewer larvae than those left untreated.


    Single treatments of emamectin benzoate can protect trees for two years, possibly three (research is continuing). This product is applied via a micro-injection system starting in May/June through approximately October.


    TREE-age™ is well established and recognized in its ability to save trees from the Emerald Ash Borer.


    The active ingredient also treats for Lilac-Ash Borer.


    Tree-age™ rapidly degrades upon exposure to sunlight preventing pollen and leaf transference.


    New Heights does not use neonicotinoidal pesticides (imidacloprid eg. Merit™, Bayer™ or dinotefuran eg. Safari™) due to lasting residual concerns,  bee/ pollen transference, and unintended consequences associated with soil drenching and soil injection.


    We are also following the use of the bio-pesticide, TreeAzin by the Canadian Forest Service and BioForest. It  is derived from seed extracts of the neem tree. TreeAzin is best applied prior to bug presence in tree, and is not effective when canopy dieback passes 30%.


  • Yes, Emerald Ash Borer applications protect tree from Lilac Ash Borer but Lilac Ash Borer appliations do not protect for EAB
