How Do You Overwinter Strawberries?

By: Jessie Keith

How Do You Overwinter Strawberries?

“What do you do with strawberry plants in the winter?” Question from Jacklyn or Portland, Oregon

Answer: In mild areas like yours, strawberries (Fragaria spp., USDA Zones 4-9) are very hardy, so no special overwintering measures need to be taken. You can, however, clean them up and thin clumps that are over 3 years of age to encourage strong fruiting. Central plants that are three or more years old start to produce less and less fruit. If you replace the main plants with one of the plant’s newer offshoots, you will get more strawberries the following year.

Start by weeding around your strawberry plants. You can also protect them with light straw or leaf mulch around the base of the plants. If you have older strawberries that need to be thinned and replaced, remove the central plant, and plant in its place one of the larger offshoots that have rooted. Fertilize your new strawberry plants with an all-purpose slow-release fertilizer to encourage good rooting and growth through fall and again late winter. Feed once more in early to mid-spring.

From there, I encourage you to watch our video about everything that you need to know about growing strawberries.

Happy gardening,
