I often have clients who contact me because branches on their trees are dying. Their assumption is that there is something going on directly in the branches that is causing the dieback. While that can be the case, there are also a myriad of other reasons why tree branches can die. Here is a laundry list of what I commonly see causing branch dieback in my clinic.Continue Reading

I am always paying attention to the tree stresses that come over the past few years to see how they play out, interact, and affect the tree populations, both in natural systems and in home landscapes.

While trees are living organisms, just like us, there are many differences between the ways we grow, deal with stress, and recover from damage. One of the biggest differences between trees and ourselves is trees never really heal.Continue Reading
Most healthy trees should have leaves with an even green color. Leaves should also have a similar size, density, and an even distribution throughout the tree. If a tree exhibits a yellowing of leaves with a network of darker green veins (interveinal chlorosis), this likely indicates a serious nutrient problem. In severe cases the entire leaf turns yellow and leaf size is stunted. Leaves may scorch or wither and drop prematurely. Symptoms may be on a few leaves, an individual branch, and portions or all of a tree.Continue Reading
When a tree must be removed and the chips have settled, deciding what to replace it with often comes next. Emotions and practicality aside, there are several questions that can help make that decision. What is the primary objective of a new tree? What will best match the site and thrive?

Ten years ago, I wrote an article for this newsletter about the state of emerald ash borer (EAB) and what the future of ash trees looked like then. If you have kept past newsletters, you will find the full article in the winter 2013 issue. At that time, EAB was relatively new in our area and most ash were not yet affected by this destructive insect. Fast forward to today, we have progressed upward on the mortality curve. Thankfully, death does not overrun the current story for all ash trees.Continue Reading

Guess Which Insect? A sloppy painter might finish up the ceiling work and call it day. Cleaning off the brushes with some water and flinging the excess moisture and leftover paint onto the shrubbery. Once this dries you might find tiny white flecks on the needles of your Mugo Pine (or other evergreen host). Maybe it’s a stretch, but this does come around to a tree care topic. These white paint flecks mimic the look of a tiny insect that can damage your trees or shrubs if left alone.Continue Reading
