Pest Alert: Emerald Ash Borer
The Emerald Ash Borer (EAB) has demonstrated its ability to move quickly across our Commonwealth, irreparably destroying many Ash trees in its path. Recently, the exotic flat-headed borer has sprung up in the Shenandoah National Park.
The promising news: there is strong evidence that through the application of systemic controls, individual ash trees can be inoculated against this pest. The time to act is now, before EAB attacks your Ash tree. Unfortunately, the chances of an Ash tree’s survival significantly decline after an EAB has laid its eggs in the tree.
For more information on EAB, please visit: www.emeraldashborer.info. To arrange a complimentary inspection of your Ash trees (or if you are unsure if you have Ash trees), please call our office at 434.982.8733 or email email@example.com.
Leafminers are the most serious pest that attack Boxwood. The most widely accepted treatments in the industry for Leafminers are likely contributing to the decline of honey bees cased by Colony Collapes Disorder (CCD). In all likelihood, using these conventional treatments is doing a disservice to the environment. At Van Yahres Tree Company, we can severely limit impact on the honey bee population by using a number of methods to improve the health and vigor of the Boxwood. We welcome an opportunity to meet with you to examine your Boxwoods and, if necessary, talk about alternative treatments.
To arrange a complimentary inspection of your Boxwoods (or if you are unsure if you have Boxwoods), please call our office at 434.982.8733 or email firstname.lastname@example.org.

Mulching is the most beneficial thing a home owner can do for the health of a young tree. Mulches are materials placed on the soil surface to improve soil structure, oxygen levels, temperature and moisture availability. Properly applied, mulch can give landscapes a handsome, well-groomed appearance. Starting 1 to 2 inches away from the trunk spread a 2 inch layer to desired width.
A mulch “volcano” (pictured at left) can:
- Cause inner bark tissue to die;
- Lead to insect and disease problems;
- Promote excessive soil moisture and promote root rots;
- Create habitat for rodents that chew the bark and girdle the stem;
- Lead to anaerobic conditions that produce alcohols and organic acids toxic to young plants;
- Cause imbalances in soil pH; and
- Become a matted barrier that prevents the penetration of water and air.
Post Storm Inspection
The severe weather in our area has sadly caused much damage to valuable trees and landscapes across the entire region. It’s important to assess your trees and shrubs for hidden dangers after storms strike to avoid costly damage in the future.
For storm damage clean up or other tree and shrub care needs, our certified and insured arborists will provide an honest and complimentary assessment.
Anti-desiccant Treatment Helps Prevent Winter Burn
Wind and cold weather can lead to winter burn, browning and leaf drop. To reduce the moisture loss from your evergreens, our GREENWatch program recommends an anti-desiccant treatment right now on species such as boxwoods, hollies, laurels, magnolias and rhododendrons. This application will close pores to withstand the winter and will slowly wear away for them to reopen in the spring.
