Summer 2010 - Two-Lined Chestnut Borer

Summer 2010 Newsletter in Adobe PDF format

By: Jean Ferdinandsen Certified Arborist WI-0149A

Two-lined chestnut borer was a principal pest of American chestnut. Now it is a common secondary invader in oaks. This insect pest only invades weakened trees. It is probably the most important insect cause of oak mortality. Outbreaks usually follow extended periods of drought or defoliation by insects such as gypsy moth or tent caterpillars. Other stress factors such as soil compaction, construction damage, trunk or root injury, or chlorosis can predispose trees to invasion by this insect.

Summer 2010 - To Be Green Again

Summer 2010 Newsletter in Adobe PDF format

By: Ron Gumz Certified Arborist MN-0324A

As you gaze around the landscape, you may notice many colors of various trees and shrubs, especially of the foliage. You can appreciate the color of a blue spruce, the maroon in a Crimson King Maple, spring's golden color of a Sunburst Honeylocust, or the white tones of a dappled Willow. These special colors are more of an exception than the rule. Most trees are designed to have green foliage. When trees (that are supposed to be green) start looking a pale yellow color, it can be a sign that the tree is suffering from a condition called chlorosis.

Spring 2010 - Combating Aliens

By: Bill Reichenbach, Certified Arborist WI-0188A

Spring Newsletter in Adobe PDF format The news is full of troubling accounts of exotic species making inroads to our environment. Numerous foreign plants, insects, disease organisms and animals threaten our natural environment. Many of these organisms can become invasive, their populations growing quickly without natural controls from their place of origin. Some are perhaps only a nuisance, like the Asian lady beetle invading our homes in fall. However, many have the potential to wreak havoc on our natural environment. The emerald ash borer, zebra mussel, and Asian carp, come to mind. These exotics have the ability to change the face of our landscapes. Their costs will be huge, and not just in the dollars spent trying to contain their spread.

New research has identified many of the types and numbers of beneficial bacteria and fungi that are required for a healthy root system. Gardeners know that compost is a secret to improving sterile urban soil and growing healthy plants by providing these beneficial microorganisms. A new method called compost tea, takes the benefits of compost, multiplies it and puts it into a liquid form for easy delivery to the roots where it is needed.

Winter 2010 - Spring Cleaning Feels Good

By: Anthony C. Arnoldi, Board-Certified Master Arborist WI-0102B

Spring Newsletter in Adobe PDF format There is something about spring that motivates you. Things are warming up, color is returning, and the hibernation sluggishness begins to wane. The increasing energy makes me look around and take notice of all of the things that accumulate and fill various nooks and crannies (and even more) around the house,garage and yard. Piles of unread magazines, paperwork and mail needing to be dealt with; a faulty Christmas decoration; a few boxes of clutter in the garage; a broken bird feeder that needs to be thrown out; fallen branches and litter caught in the bushes that need to be cleaned up are all representative of the job before me. Sure, it takes some effort, but it sure feels good to be rid of the weight of all that from my to-do list, and things just shine and sparkle a bit more!
