INSECT AND DISEASE CONTROL

Schedule insect and tree disease control in Hendersonville, NC

Many insects and disease organisms are attracted to the trees and shrubs in our landscape. Insects and diseases can cause significant injury and compromise the health of your landscape plants and trees. Proper identification and diagnosis are necessary in order to recommend a treatment program. There are a number of insect and disease issues that require annual control programs, whereas others can be scheduled on a two- or three-year schedule. Our ISA Certified Arborists can design a treatment program specific to the plants and trees on your property.

INSECT CONTROL

Damage to tree leaves and stems is often the first sign of a bigger tree problem, possibly an insect infestation. Aphids, Cankerworms, Japanese Beetles, Borers and Woolly Adelgid are common culprits!

Hemlock Woolly Adelgid:



  • Symptoms:Barely visible to the naked eye, the insect and its egg sacs are covered with a waxy, white “wool.” The sacs, most prominent in late spring, look like the tips of small cotton swabs clinging to the base of hemlock needles. In the beginning, your plant will struggle a bit. You’ll see discolored evergreen needles that may drop early coupled with a lack of growth. If left untreated, the pest will continue to do more and more damage to your tree or shrub. Ultimately, your plant will die without your help.
  • When to tread your hemlocks: Best between mid-May through September.


Aphids:



  • Symptoms: Leaf curling, twig dieback, a sugary substance called "honeydew," black, sooty mold and stunted growth
  • When to control aphids: Talk to your arborist as soon as you spot symptoms.


Cankerworms:



  • Symptoms: Chewed, ragged-looking leaves that fall prematurely in spring
  • When to treat cankerworms: Control this pest in spring and focus on cankerworm prevention in fall.


Japanese Beatle:



  • Symptoms: Chunks of leaves chewed down to the veins, browning leaves around the top of the tree canopy and leaves falling in summer
  • When to treat for Japanese beetles: Act during peak growing season, from mid-June through August.


Eastern Tent Caterpillar:



  • Symptoms: Large, silky spider webs and tree leaf loss, especially on black cherry trees
  • When to treat: Clip and destroy the tents. Wait until winter to remove the silky webs. Your arborist can also apply a treatment to control the larvae.


Borers:



  • Symptoms:Boring insects feed within tree trunks or branches. Thinning and yellowing leaves, holes in the bark, and canopy and bark loss are common signs. Most borers target trees that are under stress from drought, injury, flooding, poor planting, etc.
  • When to treat:Depending on the type of borer and tree or shrub, treatments take place from May to August and done normally 1 week after the first bloom.
