Japanese Beetles and Scale are Back!

Just about this time last year, we were starting to see a number of trees and shrubs with Japanese beetles. Japanese beetles seem to appear overnight and can defoliate a shrub within hours and a tree within days.

Easy to distinguish by their opalescent head and copper-colored body, they emerge in early June from their larvae stage and immediately seek out food. Once they start to dine on the leaves of their host, the damaged leaves emit an odor that attracts even more beetles. Japanese beetles prey on a variety of trees and shrubs, but favorites are linden, crabapple, apple, Norway maple, pin oaks, birch, fruit trees and rose bushes.

Response time to treat your trees and shrubs should be immediate. If you see signs of Japanese beetles in your landscape, contact your local Arbor Masters to treat your trees and shrubs … Read More »

The battle to control weeds, grubs and fungus can what seem never ending. During summer months, grubs can be especially harmful to your lawn.

Tree Diseases on the Rise

As we move into the growing season, your landscape might begin to show signs of distress. Insect damage or environmental issues from the previous year can appear as trees and plants start to leaf out. There are many insects and diseases that can affect your landscape.

What are the most common tree diseases?

Iron Chlorosis – A lack of sufficient iron within the tree causes the leaves to yellow while leaving the veins of the leaves green. Most often seen in oaks, sweet gums, birch and azaleas, it is treatable with an iron injection. Left untreated, trees can suffer from leaf and branch die back.

Oak Wilt – This disease is a fungus that attacks oak trees and if left untreated, is 100% fatal. It is more prominent in spring when new wood is being formed. Key symptoms are discolored leaves and defoliation. … Read More »

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

Spring Is Right Around the Corner

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 »
