The Boulder County Extension has had a Master Gardener program for 51 years — one of the first in Colorado — founded in 1975 by Horticultural Agent Barbara Hyde. For 41 of those years, I’ve been privileged to serve as a volunteer, one of the most rewarding and engaging experiences to which I look forward every season.
Over 1,200 Master Gardeners have been trained in the county over the program’s history, with about 100 currently active, who in 2025 provided 3,620 hours of volunteer service to at least 4,000 home gardeners (not only property owners but also apartment or condominium occupants who plant in containers or community gardens).
The purpose of the program is to educate and assist home gardeners with resources to answer gardening questions. It currently trains an average of 10 to 20 new MGs each year with a curriculum developed by Colorado State University. Each year MGs are required to provide many hours of volunteer service and take educational courses.
Among the volunteer opportunities, MGs staff tables at garden centers like Ace Hardware, Jax and farmers markets during the growing season, respond to phone inquiries all year, and participate in specially trained teams. The tree team makes site visits to assess tree problems, the diagnostic team on which I serve evaluates plant samples brought to the extension office, and a new team is being formed to conduct site visits to diagnose turf problems.
This year Master Gardeners also have helped childcare centers plant gardens through the Farm-To-Early-Care-and-Education program, distributed over 5,000 native plant seedlings to the public as part of its Sustainable Landscaping initiative, and provided community-wide education about invasive species like emerald ash borer, Japanese beetle and the Asian jumping worm. The Food Pantry Garden donated over $2,500 worth of food to local food banks. MGs have created and continue to maintain demonstration gardens at the Extension office and the Native Plants Demo Garden at the Longmont Public Media building that help gardeners create environmentally sustainable plantings.
MGs provide this service based on their training and experience, and professional horticulture and small acreage staff oversee their work. The logistics of arranging for the various volunteer activities and assuring they are fulfilled (in addition to managing the annual training of new recruits) is a vital administrative role of the Master Gardener coordinator.
While there is a lot of gardening information online, including science-based CSU materials, web resources and AI cannot provide sufficient or fully accurate information for all gardening questions that address our local environmental conditions. In fact, web-based information can be misleading or false. We often hear from gardeners with lawn problems, for example, that they “diagnosed” the situation as insects or disease (rather than the more common irrigation issues) and applied pesticides — useless, wasteful and often environmentally harmful. There is no substitute for local volunteers trained to answer home gardener questions along with professional Extension staff. Our training includes not only the latest science-based horticultural information but also how best to communicate that knowledge in a way that gardeners can understand and utilize with sensitivity to their individual situations.
In short, therefore, besides helping with vegetables (including food for those in need) and home and community flower gardens, the Extension diagnoses landscape diseases, insects and environmental problems, promotes water-saving landscapes, provides early detection of newly invasive pests, diseases and plants, and is actively involved in preserving the county’s urban forests (which assist carbon sequestration, wildlife habitat and environmental cooling). MGs provide these services by translating university research into practical, neighbor-to-neighbor education.
It has been a privilege to provide this service — a continuing education for myself and a joy to share knowledge with gardeners who always express gratitude for our help.
While I fully appreciate the county’s severe budget problem and that hard choices must be made, I urge the commissioners not to cut the home horticulture staff, master gardener coordinator and small acreage specialist.
I hope that Boulder County residents who’ve benefited from our help over the decades will tell the commissioners how much they value this service – either via email ([email protected]) or at the Oct. 22 public hearing on the county budget.
