Overwintering Strawberry Pots in Oregon: Preventing Losses

Strawberries are hardy to zone 4, but container roots freeze faster than ground-planted ones. In Oregon’s harsh winters, move pots to an unheated garage or basement (above 20°F). Refresh soil annually—old mix may harbor red stele root rot. Pinch off runners to direct energy into larger berries rather than more plants.

If plants died despite hardiness, check for root rot: brown, mushy roots and a foul smell. Discard infected soil and sterilize the pot. With winter protection and fresh soil each spring, container strawberries produce reliably for years.
