University of Idaho Extension, Kootenai County U-Idaho Extension Image Map

Do you have questions about growing in Northern Idaho? UI Extension uses volunteers for research-based horticulture education. We help you find the answers you need and offer informational classes and workshops. 

Idaho Master Gardeners develop and share expertise in a broad range of home horticultural topics, including food production, integrated pest management techniques, improving soil fertility, choosing the right trees, growing turf grass and sustainable yards and gardens.

“Helping people grow” is the motto of the Idaho Master Gardener program, reflecting UI Extension’s goal to help meet the needs of growers in our local communities.

Many of your home and garden questions and problems can be easily addressed at our Plant Clinic by an Idaho Master Gardener.

Our Kootenai County Program handles parcels up to 5 acres.  If you are on a larger parcel, have questions about developing into the commercial market or are involved in retail (nursery, landscape or Christmas tree) please call us so we may refer you to the correct individual within the UI system.
