The Horticulture Program at Pickens Technical College is looking for arborists to speak on February 16th at their Arborist Chat. It would be to speak at two classes; the first runs from 7:50 to 10:40am and the second from 12:05 to 2:55pm. We are excited to engage college students in the arborist industry. If you are interested in being part of this program, please reach out to Rachel Durkan (rmdurkan@aurorak12.org) and Patrick O'Meara (coloradoarborist@aol.com) before February 10th.


They are also looking for guest speakers to present about arboriculture at a couple of classes that are held Tuesday through Friday February 14 – March 24. The goal of the class is to provide students with a basic understanding of what goes into being an arborist. Topics can range from safety, to common tree pests, equipment used, identification of hazardous trees and any other topic you may want to present about. For guest speakers there are two classes - the morning runs from 7:50am to 10:40am and the afternoon is 12:05pm to 2:55pm. Having someone speak at both classes on the same day would be the easiest but if it needs to be split for the two days that is okay. Please reach out to Rachel Durkan (rmdurkan@aurorak12.org) before February 10th if you are interested.

Water is vital to plants. Without it we wouldn’t have any trees or shrubs. This is especially true in Colorado. Did you know that most of the Front Range is considered a high plains desert? What exactly is a high plains desert? It’s a cold, semi-arid environment that receives up to 20” of rain annually. It is also common to experience huge temperature swings. Combined with wild weather events, this creates an extremely stressful environment for our trees and shrubs to survive. This is exponentially true during our warm, dry, windy winters. One easy solution to help our trees and shrubs thrive during the winter is by winter watering. CONTINUE READING

Winter Horticultural Oils

When & Why to Use Them


As the days shorten and get colder in the late fall, most of us shift our focus from pest management to other winter services. Certainly, winter watering, pruning, and snow removal are important, but it’s easy to forget about horticultural oils and their place in our Integrated Pest Management programs.

Spring start up, where do I begin…


Over the winter, you should be checking for mite damage in turf and ornamental plantings especially if we are having a dry winter. In turf, SW facing areas are particularly susceptible. If mites are detected, there are several Miticides/Insecticides/Ovicides to choose from. Look for A/I’s: Bifenthrin (Bifen 7.9), Abamectin (Lucid), Bifen XTS, Hexygon (Hexythiazox). CONTINUE READING

PEST ALERT: Linden Bark Borer Moth


Insect pests in the U.S. have a recurring tendency of introduction at the populous East Coast ports of

entry. Japanese Beetle, Brown Marmorated Stink Bug, Spotted Lanternfly, European Paper Wasp,

Amauromyza pleuralis and Emerald Ash Borer are but a handful of species that have followed this trend.

Naturally these introductions have led to establishment and range expansion westward. Colorado’s Front Range landscapes provide enticing conditions for continued progression.
