The Lewis-Clark Valley has a growing season of over 200 days. Home gardeners and local commercial enterprises take advantage of the extended growing season in a variety of horticultural interests. A wide range of gardening inquiries are answered annually concerning plant variety selection, culture, husbandry, and pest control by our master gardeners and horticulture staff. The UI/Nez Perce County Extension Horticultural Advisory Committee plays a pivotal role in identifying and prioritizing programming, classes, and seminars to meet the educational needs of the community.
Banana Belt Gardening Series
The Banana belt Gardening Series is tailored to present timely and useful information to meet the needs of gardeners of the Lewis-Clark Valley and surrounding area. The series is held annually on Wednesday evening throughout the month of February.
One of the best places to get common-sense answers for your gardening questions is the Plant Clinic, which operates during the growing season beginning the first week of May. Drop by the Plant Clinic on Tuesdays between 9:00am and 11:30am at the University of Idaho/Nez Perce County Extension Office, 1239 Idaho Street, Lewiston, Idaho.

Master Gardener Program
The University of Idaho Master Gardener Program is an educational opportunity designed to meet the gardening information needs of the community.

Individuals who are interested in becoming Master Gardener volunteers must have the enthusiasm, commitment and time to volunteer; enjoy working with plants and people of all ages; a strong interest in horticulture or home gardening; and be willing to communicate and share knowledge effectively with others.
