WINTER HARDINESS OF RASPBERRY VARIETIES 



The vfinter of 1955-56 was one during which the ground was bare and frozen

 t\ire \rent to -10° F, and -l5° F,, no severe cold prevailed. Yet this combination 

 of circumstances was sufficient to cause considerable winter killing of canes of

The listing belovf gives an estimate of the percentage of total cane length

 killing during the winter of 195U-55 is listed in parentheses.

 the injury appears to be correlated v/ith early pruning,
