Whatever effect it is that the cold has upon evergreens, the 
damage is not apparent until the winds of late March and early 
April come. Then plants, which up to that time have appeared 
green and in good condition, turn to a deadly brown within a 
few days, and the damage which has been done is startlingly 
revealed. 
The unusual conditions which seem to stand out in the past 
winter are two: first, the excessive rainfall during October and 
November, following a dry period when the plants were inactive; 
and second, the unusual cold of the following January and 
February. Neither one of these in itself would, perhaps, have 
been disastrous, but the combination of the two was destructive.
