Bagworms are Back!

Bagworms are back!

These invasive insects look like cone-shaped sacs that can sometimes be mistaken for pine cones. The sacs look like cocoons that hang from the tree branches. These cocoons or sacs contain bagworm eggs and once they hatch, they will begin to dine on the leaves and needles of your trees and shrubs. A heavy infestation on evergreens can cause extensive die-back and even death to the plant. Bagworms are  fond of a variety of trees such as blue spruce, cedars, white pines and junipers. On deciduous trees, bagworms will strip the leaves, leaving only bare branches.

Left untreated, bagworms can defoliate branches, causing branch die-back and eventually kill the shrub or tree. The best defense against bagworms is an insecticide spray application. If the outbreak is severe, a second application may be required.

 

 

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 »

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 »
