red raspberries, winter injury, horticulture research
Winter injury is an important problem in South Dakota raspberry growing. Even the most hardy varieties now available may be damaged so extensively that no fruit is produced the following summer. It has been observed that a mild winter will cause more injury than will one that is continuously cold. Because of the uncertainty of winter survival, covering the plants with soil has become a standard practice. While this is an effective way of preventing winter injury, the method has some disadvantages. Covering the canes breaks off some buds and canes. The labor cost is also rather high. It was believed that some cultural practice might affect winter survival. Four such practices were started in 1953 and are the basis for this report.
