Emerald Ash Borer

Emerald Ash Borer (EAB) is an invasive beetle that traveled from Asia in the 1990's, and as of September, 2013 has made itself a home here in Boulder. This pest attacks and kills all ash trees native to North America, which includes the popular varieties of green ash, purple ash and white ash. In adult form, the metallic green beetle causes very little harm to the trees themselves, but lays eggs in the tree. When hatched into larvae, they feed on the cambium, as shown to the left, which disrupts the nutrient transfer in the tree. Unless properly treated, EAB will kill the ash tree.

There are a number of misconceptions about what time of year is appropriate to prune trees, but the reality is that most of the trees here in the front range can be pruned any time of the year. The exceptions to this include Apples, Pears, Peaches, Hawthorns and American Elms (shown left); these trees are all susceptible to damaging diseases that can be spread during the warmer months of the year. We only prune these species during the winter when there is little to no risk of transferring these diseases from tree to tree. We also take precautions of sterilizing our tools before working on these trees to further mitigate these diseases.

Planting a tree is an excellent long term investment in your home and property. However, like any investment, there is some careful consideration that must be done when picking a variety. Some general things to think about is location, North, East, South or Western exposure, or how much light will it get? Another important consideration is the size of the desired tree, large shade tree, small ornamental, or somewhere in between. One of the most important categories to consider is how much maintenance you are willing to put into the tree over the years to ensure proper, healthy growth in the long term.
