Plant Health Care

Plant health care is a program to help identify and treat problems before they become a threat to the life of your trees. The objective of the comprehensive, long-term tree care program is to use our knowledge of tree systems to prevent or minimize stress and avoid mortality.  Once mature trees begin to decline, they do not respond well to remedial or corrective treatments.  For that reason, continuous tree care, beginning with tree selection and planting, and maintaining a stable environment around mature trees are absolute necessities for keeping healthy trees healthy!
WNCGIS can develop a program to manage one tree or your entire landscape. Typically sites are monitored quarterly however adjustments can be made to meet the needs of both the trees and the customer.
Hemlock Woolly Adelgid Management

The hemlock woolly adelgid is an aphid-like insect you can barely see with the naked eye. What you can see is the white, waxy “wool” that covers the adelgid. A sure sign of HWA infestation is tiny cottony tufts at the base of hemlock needles. The “wool” is present throughout the year, but is most prominent in late spring.
The HWA feeds on the sap at the base of hemlock needles, restricting nutrients to the foliage and causing the needles to change from a deep green to a  grayish green and then fall off. Without needles the tree starves to death, usually within three to five years of the initial attack.
HWA Management
WNC-GIS provides control options based on the hemlocks environmental surroundings and the clients objectives, including:
Foliar application of horticultural oil or insecticides.
Basal soil injection of insecticide.
Direct trunk injection of insecticide using a Tree IV system.

Tree Health Evaluations
We will determine the overall condition and health of individual trees. Identify the pest or problem within a tree, recommend treatments and perform or supervise the treatment.
Some the types of treatments we are doing:
Dogwood anthracnose management.
Maple, sycamore, beech, etc. anthracnose treatment.
Bagworm, Lilac Borer, Eastern Tent Caterpillar, etc. control.
Spider Mite management.
Micro-element deficiencies in oaks and maples.

Risk Analysis and Hazard Abatement
Inspection and analysis of trees, identifying any potential hazardous conditions. Provide recommendations and supervision for removal, pruning or other treatment methods of hazardous trees.

Tree Protection During Construction
We can identify existing trees on construction sites and determine their appropriateness for saving. Develop and implement tree protection plans which includes working with contractors to install protection barriers and follow guidelines of the plan.

Plant Appraisal
Determine an appropriate value of trees and plants based on their size, species, condition and location. Provide a written report or testify in court as necessary.

Invasive Exotic Plant Mitigation
Nonnative plant identification and development and implementation of management strategies. Constant surveillance to detect first appearance of new arrivals is recommended to prevent heavy establishment or full blown infestations of nonnative plants. Treatment methods may include mechanical or hand removal, selective herbicide application, prescribed burning or overgrazing.
