Our first sample came into the Extension office with raspberry root rot. Root rot is caused by wet soils and clay soils. The raspberry will leaf out but as the weather warms, the plant will collapse. The roots have been rotted by too much water (Oct-April) or too clay of soil or mulch being added around the plant base. Solution: Remove mulch, have loamy raised beds, build loamy berms or replanting every three-five years.

The raspberries also had Dec. 2009 winter freeze burn on the canes from ground level to six inches up on the stems.
