LIST OF ILLUSTRATIONS 



riATB PAGI 



I. The scarlet thorns planted on both sides of the wall on either side of the 

 gate make an excellent frame for this architectural detail at the garden 

 entrance Frontispiece 



II. This map shows those portions of the United States which because of 

 climatic environment and geographic location possess similar planting 

 seasons. Investigation of zones of similar planting seasons has, to date, 

 not provided complete information to the landscape architect in his 

 planting work. For supplementary information refer to Plate No. 

 Ill on Page 14. (In colour) 6 



III. A chart to aid in determining the most favourable period for transplanting, 

 and for seeding of lawns in various sections of the United States. Note 

 the long winter periods of the Northern Zones and the continuous 

 planting seasons of the Southern Zones. It is of great importance to be 

 able to plan ahead and to order plants for delivery at the proper time for 

 any section of the country. These are average seasons resulting from 

 observations of normal seasons during a period of years. For supple- 

 mentary information refer to Plate No. II on Page 6 ..... . 14 



IV. The hedge which may look unkept and ragged if not pruned will in the 

 hands of the skilled gardener assume almost any degree of refined out- 

 line. These photographs show one of our most desirable hedge plants, 



the Japanese privet {Ligustrum ibota) 20 



V. The correct pruning of trees and shrubs is a great factor in the successful 

 maintenance of landscape plantings. These diagrammatic drawings 

 together with the explanations on the opposite page illustrate correct 

 and incorrect methods of pruning 24 



VI. A knowledge of the various operations involved in the work of correctly 

 transplanting plants is essential for their subsequent normal develop- 

 ment. These diagrammatic drawings accompanied by the explanation 

 on the opposite page illustrate various transplanting operations. . . 34 



VII. Immediately after transplanting, the trunk of every large tree should be 

 protected with a covering of burlap (Fig. B) which prevents excessive 

 drying out and consequent cracking and loosening of the bark (Fig. 

 A). This protection is especially necessary during the warmer summer 

 months 40 



VIII. To most of us in the northern states the method of seeding a lawn is 

 familiar, but the method of making lawns in southern states by planting 

 Bermuda grass is little known. In these photographs small clumps of 

 Bermuda grass are being planted in "hills" staggered at intervals ranging 

 from eighteen inches to thirty inches. The thicker the planting the 

 more quickly a mat of turf can be developed 41
