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 each year concerning plant variety selection, culture, husbandry, and pest control by our Idaho Master Gardeners and horticulture staff. The UI Extension, Nez Perce County Horticultural Advisory Committee plays a pivotal role in identifying and prioritizing programming, classes, and seminars to meet the educational needs of the community.
