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.
The Plank Clinic is open for walk-ins or phone calls on:
October 1 – March 31 Winter Hours No walk-in days are available during the off season, however we are available by phone. Please leave us a detailed message and a volunteer will be in the office one day per week (variable) to return your call.

The Plant-a-Row for the Hungry (PAR) program is a people-helping-people initiative to provide hungry families with fresh, nutritious produce. Community members are encouraged to donate their surplus garden produce to help feed those in need. Free seeds and free seedlings are available for your efforts through the UI Extension, Kootenai County office. We will send you email notification when they are available. If you aren’t on our Idaho PAR email list, please email Kara Carleton.
