Any consideration of the subject of pruning evergreens, particularly conifers, should first make recognition of several separate and distinct problems of pruning. As the use of evergreens increases around residences, where trees are used in confined areas, such as foundation plantings, the need of pruning becomes most important in years past when evergreens were used largely in parks and cemeteries and on estates, for windbreaks, shelters and other purposes requiring tree-like forms, pruning was of small importance. If nurserymen nope to encourage the plantings of evergreens on small residential properties, there is a vital need that they follow some program of pruning which will help to confine trees to certain limits of size for a much longer period than normal.
