EVERGREENS

The variation in adaptation of evergreens has come to be a much-debated question among horticulturists and landscape architectswho are called upon to use them. An interesting fact is discoveredafter some study of evergreens. The hardy types are not perfectlyhardy under the varying conditions of climate and exposure in varioussections of the country. Therefore, evergreens should be selected forlandscape plantings with a considerable knowledge of their ability towithstand local conditions.

The factors which are evidently most injurious to the normaldevelopment of evergreens as a group are: (1) sudden variations inclimatic conditions; (2) condition of the soil; (3) exposure; and (4)atmospheric conditions in the vicinity of congested city districts. Ashort discussion of these factors, as bearing upon the growth of ever-greens, may be of value.
