3. Exposure. If the more tender types of evergreens whichdo not normally grow under the most severe climatic conditionsare selected for use in a section where the climatic conditions aresevere, then such plants should be so located that the exposure from theprevailing winds of winter is greatly reduced. It is possible to use mostof the evergreens shown in Group IX-A in any section of the country,provided a proper exposure is selected and the proper winter protectionis given. Many times this is impracticable, because evergreens areselected to be of equal value during the winter months and during thesummer months. There is no windbreak or screen as yet developedfor the protection of evergreens against exposure which in itselfdoes not detract to a great extent from the beauty of these plantationsduring a period of the year when their foliage should be most effective. |
