Emerald Ash Borer; the War Continues

Meet The Emerald Ash Borer

It has been fourteen years since the discovery of the Emerald Ash Borer in the U.S. To date, it has killed over twenty-five million ash trees in twenty-one states and caused millions of dollars in tree loss. Known for its iridescent green body, the Emerald Ash Borer only preys on ash trees.

How do I tell if my Ash Tree is Infected?

The signs of an Emerald Ash Borer infestation are fairly easy to recognize. The distinct signs of an infected tree are:

“D” shaped exit holes Canopy die-back Volunteer growth at the base of the infected ash tree “S” trails left by the Emerald Ash Borer located underneath the bark

Unfortunately by the time these signs are noticed, the Emerald Ash Borer has already caused extensive damage and the health of the tree has been compromised.

Battling Spring Pests

It’s spring and flowers are starting to pop up, trees are beginning to leaf out and insects are starting to invade your landscape.

What is attacking my landscape?

Spring is Just Around the Corner

With the exception of a few cold days and a few snow falls this year, the Midwest has had a warmer than usual winter. Hopefully spring is not too far behind!

While it is still too early to start planting, you can prepare your landscape for spring growth.

Late February and March are the ideal time to prune fruit trees, shrubs and ornamental grasses. Pruning trees and shrubs now while trees are still dormant will promote new growth and allow pruned areas to heal before the tree starts to bloom in spring. Prevent weeds such as crabgrass, foxtail and broadleaf from overtaking your lawn with an early pre-emergent application. A pre-emergent works on the weed seeds that may over winter in your lawn and prohibits them from germinating in the spring. Maintain the health of your ash trees and … Read More »

Protecting your Shrubs and Trees from Winter Burn

Protecting your Shrubs and Trees from Winter Burn Laura Peterson, Certified Arborist

I cannot begin to guess what this winter is going to bring; 2 feet of snow covering the ground until March, below zero with high winds and no snow until January or mild 40 degree days with sporadic snowfall and 2 inches of ice covering everything in March. Whatever conditions occur this winter it is bound to be dry for the evergreens. Soil moisture is a factor, but the almost constant winds from November through February are extremely drying and damaging to evergreens.

Drying Winter Harms Trees

Native evergreen trees and shrubs are well adapted to our winters, but the majority of plants in landscapes are not native and don’t have the resources to combat the drying winds.

Plants lose moisture through pores in the leaves. If there is not sufficient soil moisture, … Read More »
