The Extension Service is here to serve the residents of Columbia County, providing knowledge from universities nationwide. We provide research-based information to families, youths, schools, agricultural producers, home gardeners, foresters and governments.
Our office offers a variety of programs, which include 4-H Youth Development, Home Gardening, Agriculture and Small Farms, Family and Community Health, Forestry & Natural Resources and Master Gardeners.
We publish three newsletters from our office:
- Country Living (gardening and farming topics),
- Tall Timber Topics (forestry/wood lots), and
- Columbia Columns (for 4-H members and leaders).
If you would like to receive these newsletters by email or mail, please give the office a call.
