When to Plant in Eugene, OR

Eugene, Oregon, enjoys a gardening season defined by a median last spring frost on April 22 and a first fall frost occurring on October 19, providing approximately 180 frost-free days for gardeners. These frost dates offer a framework within which to plan various planting activities and to optimize the growth season for a variety of crops and plants.

The city experiences a marine west coast climate characterized by mild, wet winters and dry summers, creating a unique horticultural environment.
