Winter 2019

Emerald Ash Borer

Emerald Ash Borer (EAB) has now been found in many parts of New York, New Jersey and Connecticut. We are recommending that every property owner in our region with ash trees discuss a management plan with their arborist. If you decide to remove your ash trees, winter is a good time to do it. If you choose to treat or inoculate your trees, it is better to wait until Spring. Either way, schedule a visit with your arborist as soon as possible.

Emerald Ash Borer (Agrilus planipennis) is a tiny, half-inch long, invasive insect that infests and kills native North American ash species, including green, white, black and blue ash.  The female beetle lays its eggs in cracks or crevices in the bark of the tree. Upon hatching, the EAB larvae feeds on the layer under it — which causes disruption of life-sustaining sugar, water and nutrients through the tree. Most trees die within 2-4 years of being infected with EAB.

Signs of EAB on your ash trees, include:

  • Tiny D-shaped holes, S-shaped galleries and splitting bark (see image on top right).
  • The presence of the small, metallic green insect (see image on bottom right).
  • Thinning crown of the tree – due to lack and water and nutrients.
  • Excessive sprouting — new growth at the base of the trunk or on the main branches of the tree.
  • Woodpecker damage — EAB are often sought out and attacked by woodpeckers.
  • Look for “blonding” effect on bark on southern side of tree stem (see image on top-left).

Do you have a management plan for EAB?

Storm Damage Prevention

Our aim was to set yearly and long-term goals for our company and determine strategies for achieving them with input from our staff... (more)

Beech Leaf Disease

Beech Leaf Disease (BLD) is a relatively new disease (discovered in 2012) that affects American beech (Fagus grandifolia), European beech (Fagus sylvatica) as well as Oriental beech (Fagus orientalis). An otherwise healthy-looking tree first develops deep green patches between the veins of its leaves. In a later stage, the leaves become thick and leathery and eventually crinkle up. The buds on these branches also die and stop producing leaves... (more)

Trees to Consider:


Tuliptree is a fast-growing tree with bright green leaves that resemble tulip flowers in profile and turn golden yellow in fall. It has greenish-yellow flowers that are located high in the tree and its stems are aromatic. George Washington planted many in his gardens at Mount Vernon. It was also used by Daniel Boone for his famous 60’ dugout canoe.... (more)

Antidesiccant Treatment
