Volunteer Spotlight: Jeff Cole

Colorado Master Gardener℠ (CMG) volunteers are a dedicated group of individuals that are knowledgeable and passionate about sharing gardening, landscape and horticulture education. This month, we are highlighting Jeff Cole!

When did you join the Colorado Master Gardener program?
Why did you join the program?
I have a degree in Biology and have always been interested in plants. I saw this as an opportunity to learn more about plants and help people learn more about gardening."

What is your favorite activity?
"I enjoy answering people's questions about gardening, whether it be at a garden center, a demonstration garden, on the phone, or online. I also like plant diagnostics where we try to figure out what is ailing a plant."
Silo Shares the Bounty
By Judy Kunz, CMG
Give Master Gardeners some open ground, a few seed packets and a job to do and they’ll turn that space into a productive garden.

That’s just what CSU Arapahoe County Master Gardeners have been doing since 2012 at Silo Park vegetable demonstration garden in Greenwood Village.

In partnership with the City of Greenwood Village, Master Gardeners plan, plant and maintain the 2,200 square foot garden and harvest the vegetables, fruit and herbs grown there. They have steadily increased the yield each year and have harvested a total of approximately 8,800 pounds of produce, donating it to feed the hungry.
The Lima Plaza Pollinator Garden is Underway!
By Lucinda Greene, Colorado Master Gardener℠ Program Coordinator
The Lima Plaza Pollinator Garden is underway! After several months dedicated to design, planning, development approvals, fundraising, and bidding the Colorado Master Gardener℠ Volunteers in Arapahoe County are ready to start the planting the garden. Groundbreaking is set for 9/11/2019 at 8:00 a.m. 

The Lima Plaza Pollinator Garden is a 2200 square foot space surrounding the CSU Extension office in Arapahoe County. This teaching garden is designed to provide education about the impact of pollinators in our ecosystem, the use of native and low-water plants that can attract pollinators, and alternative uses for non-practical turf areas.
From the Hort Desk
Part of the land grant university mission is to bring the latest research to our community and part of my job as an Extension Agent is to help facilitate that process. I want to share a recent experience I had on the front lines of research.  

In July, I had the privilege of participating in the International Pollinator Conference in Davis, California. Researchers and land managers from all over the world gathered together to discuss the challenges facing pollinators. I was amazed to hear about the great work being done in the United Kingdom, Germany, Thailand, Australia, Canada, Japan, Brazil, Sweden, and France.

Fall Lawn Care
To-Do List

By Martha Kirk, CMG
Mow the lawn at the same height (2 ½” to 3”) all year; no need to mow shorter in the fall. Remove just 1/3 of the turf height each mowing.

Core Cultivation
Aerate the lawn early September to mid-October. Water the lawn 2-3 days in advance to soften the ground and achieve deeper plugs. Fertilizer application and overseeding can be done at this time.

The most important nutrient for lawns is nitrogen. If fertilization is done only once per year, the best time is the fall (October-November) when the grass is still green. Always water well after applying fertilizer. 

 Fall is a good time to overseed if the lawn has patchy spots. The soil is warm so germination will happen quickly. Prep the area by creating multiple holes in the turf. This can be done manually with a garden fork or with a core cultivator.
A Closer Look

Dragonflies and damselflies belong to the insect order Odonata. Odonata means “toothed one” in Greek which refers to the insect's chewing mouth parts. There are currently 108 species of dragonflies and damselflies known in the state of Colorado. Dragonflies hold their wings horizontally and outstretched when they are resting, while damselflies hold their wings together and above their bodies when at rest.

Dragonflies are the top insect predators of the air and are capable of feeding on dozens of mosquitoes, midges and gnats in a short period of time.

Arapahoe County Master Gardeners in the Community
The Master Gardeners have been busy educating the community in a variety of ways including staffing booths at local garden centers, managing the demonstration gardens and working the help desk. Here are a few other events that the Master Gardeners participated in this summer.
Apprentices Ellen and Renee, and Master Gardener, Deena, staff the Floriculture Open Class competition at the Arapahoe County Fair. The Floriculture and Horticulture Open Class competitions offer a chance for residents to show off their prized flowers and vegetables.
Master Gardeners Zandy, Sandy, Janet, and Barb enthusiastically hold up a bag of over 5,000 Japanese beetles. They are counting the beetles in research traps twice a week at Hudson Gardens and Sterne Park. The data will contribute to Dr. Cranshaw’s research on Japanese beetles biocontrols.
Apprentice Colleen educates people about the importance of pollinators at the Parker Honey Festival. The booth featured native bees, honey bees and other pollinator specimens to give attendees a close-up look at bees they can observe in their own gardens. 
Arapahoe County and Douglas County staff and Master Gardeners provide seeds and information at the Gregory Alan Isakov concert at Red Rocks. Gregory Alan Isakov, a musician and local farmer, endorsed the Master Gardener program at the concert by playing a promotional video.
