MUCH OF THE UNIVERSITY of Minnesota small fruit research takes place at the North Central Research and Outreach Center at Grand Rapids, where horticulture, agriculture, and forestry research has been under way since 1896. Here, fruits, vegetables, trees, shrubs, and flowers receive their maximum test for winter hardiness
at the coldest horticultural research center in the continental U.S.
BLUEBERRIES, CURRANTS, and strawberries are grown as ornamental plants, as well as for fruit. Strawberries, currants, gooseberries, and raspberries are easy to grow in most of Minnesota. Blueberries require acidic soil, with a pH of 4.0-5.0. Have your soil tested through your county Extension office.
Strawberries can be grown as a ground cover and usually benefit from winter protection. June-bearing strawberries produce a large, concentrated crop in late spring. Everbearing types produce two smaller crops, one in late spring and one in early fall. The newer day-neutral plants are capable of producing fruit throughout most of the growing season. Strawberries normally yield 5 to 10 pounds of fruit per 10' of row.
Currant and gooseberry plants are easy to grow and do best in soils with a pH of 5.5-7.0. Hardy and productive, they provide fruit for jams and desserts. A mature gooseberry or currant can produce up to four quarts of fruit annually.
