Planting Strawberries

      From strawberry jam to fruit salad, nothing says summer quite like the succulent strawberry.
      What's more, these sweet berries are also packed with Vitamin C, fiber and potassium. So think about enhancing your edible landscape with healthful strawberries this spring. It's best to plant them in late March through April after the threat of hard frost has passed in western Oregon. OSU Extension Service Community and Urban Horticulturist Weston Miller showed us how.

      Produce one crop per year in June to early July, typically for four weeks each year.
      Produce many runners, which are above-ground stems that grow over the soil surface and forms "daughter plants" from the buds. These new daughters can be managed to increase the yield of the strawberry patch.
      Grow June-bearers in the matted row system. Set plants about 12 to 15 inches apart in the row or in the raised bed, with 3 to 4 feet between rows. Allow the early runners to develop and root. Sweep them into the row area, but keep the path between the rows clear by cutting late-forming runners.
      These older varieties are good: Hood, Puget Reliance, Shuksan, Totem and Benton.
      The cooperative breeding program between the U.S. Department of Agriculture and OSU released these new varieties that Strik recommends: Sweet Sunrise, Sweet Bliss, and Charm. Sweet Sunrise and Charm were released in 2012; Sweet Bliss, 2011.
      Puget Crimson, released in 2011 by Washington State University, is also good.
      Produce a crop almost continuously from late May until frost in the fall. Day-neutrals in the yard for fresh fruit all season and your favorite June-bearing varieties for producing lots of high-quality fruit for freezing and jam making in summer.
      Produce relatively few runners compared to June-bearers.
      Grow day-neutrals in a hill system. Set plants 12 to 15 inches apart in double- or triple-wide rows. Paths between the rows should be about 1-1/2 to 2 feet wide. Cut off all runners every few weeks.
      The large-fruited varieties Albion and Seascape and the small-fruited, but better-tasting Tristar and Tribute.
      Are better suited than ever-bearers or June-bearers for container gardening in barrels, planters or hanging baskets.
      Produce two crops per year in June-July and in the fall.
      Produce few runners.
      A common problem with strawberries is that people tend to keep their strawberry patch in the same spot too long.

      Keep your strawberries in the ground for five years, including the planting year. Older strawberry plants show lower yield and smaller fruit size, often due to virus infestation. For this reason, do not establish your new patch with daughter plants or runners from the old patch - these plants will likely get a virus too. Instead, buy new certified disease-free plants from a nursery; this is a good time to experiment with new, recommended varieties.
