The Central Oregon Horticulture Program is responsible for providing education to the residents and commercial green industry of Crook, Deschutes, and Jefferson Counties. We provide this education through seminars, workshops, publications and several other ways.
We also serve as an outlet for all of your gardening questions. You can either call or visit our plant clinic. We will assist you in identifying your weed, disease, and insect problems and recommend safe and research- based management for these issues.
The Horticulture staff and local OSU Master Gardeners give presentations on regional garden topics throughout the year. We also have several garden publications available to you at little or no cost. We provide annual OSU Master Gardener training in the tri-county area for those interested in a great volunteer opportunity.
The High Desert Gardening Newsletter is published 5 times a year. A sample copy is available for you to view. The cost is $10 per year for a color, mailed copy and a one-time set-up fee of $5 to receive it by email. To subscribe, print and mail in this order form.

For current volunteers only
The OSU Master Gardener™ program is entering its 36th consecutive year, serving Crook, Deschutes, and Jefferson Counties. Over the years, this program has trained hundreds of volunteers and they, in turn, have reached thousands of clients within our communities.
The program targets individuals interested in learning and sharing research-based gardening information. Currently, the program has over 90 active volunteers who find the program educational, fun and very rewarding.
The OSU Master Gardener™ Online Training offers the opportunity to become a certified Master Gardener and to earn the Master Gardener badge. In addition to the basic training course, participants are required to put in 40–70 hours of volunteer work at their local OSU Extension office.
"Certified OSU Master Gardeners are highly trained volunteers who share the art and science of sustainable gardening and OSU resources in home horticulture with the citizens of Oregon". More than 3,500 people across the state have become Master Gardeners through the OSU program.
Topics included in the Master Gardener basic training course include botany and entomology; integrated pest management and pesticide safety; soils, fertilizers and composting; ornamental, herbaceous plants and woody plants; vegetable, indoor and container gardening; sustainable landscaping; and plant pathology.
Registration for this class is online at: http://ecampus.oregonstate.edu/mastergardener
The Master Gardener online course is offered by the OSU Extended Campus (Ecampus) and Extension Service.
