INJURY TO PLANTS IN THE GARDEN BY FROST ON 



MARCH 27 



Following an extensive period of unusually warm weather 

 the temperature dropped to 22° F. on the morning- of March 

 27. This low temperature caused the killing of all hlossoms of 

 trees and shrubs, most of the leaves, and in some cases the 

 twigs of last year. In a few cases the injury extended into the 

 old wood, and some trees and shrubs were killed back so that 

 they had to be cut to the ground or removed altogether.
