AMERICAN FORESTRY 



The frequency of watering can only be determined 

 by actual practice, being dependent on atmospheric 

 conditions, soil, sunlight, wind, etc. During average 

 summer weather the plants should be watered once 

 a day, and this should be done after sunset if possible 

 to prevent scald- 

 ing of the plants. 

 The foliage should 

 be washed in the 

 process of water- 

 ing to keep the 

 leaves clear of 

 dust, which clogs 

 the air pores, to 

 the detriment of 

 the plants. 



The red spider 

 and the green 

 aphis are the chief 

 insect enemies 

 that are liable to 

 attack plants. A 

 thorough syring- 

 ing of the foliage 

 on both sides will 

 eliminate the red 

 spider, and spray- 

 ing with a tobacco 

 solution e r a d i - 

 cates the aphis. 



In selecting the 

 plants to be used 

 in the window 

 boxes, special at- 

 tention must be 

 given to the 

 amount of s u n - 

 shine they receive. 

 All plants require 

 plenty of light, 

 but some make 

 lesser demands for 

 it than others. 

 Plants which do 

 not demand the 

 maximum amount 

 can be used on 

 the north side of 



buildings or in shaded situations. J< is easy to overdo 

 the use of certain conspicuous plants of trailing habit, 

 which give an undesirable "weepy" effect, due to the 

 great profusion of hanging vines. Color combinations 

 are important, of course, and the colors of blossoms 

 must be considered in selecting the plants. Against 

 light stone or stucco, red, purple, or scarlet will look 

 well, and blues, yellows, and whites with as much green 

 as possible as a background make a pretty contrast with 

 the red brick building. Flowering plants should pos- 

 sess the qualities of rapid development and profuse-

EFFECTIVE ARRANGEMENT FOR AN ENTRANCE 



The fresh, rich green of the English ivy and geraniums in the boxes, and the bay tree in the tub, makes 

 an attractive contrast with hot pavements and the severe architectural design ofr the modern office build- 

 ing. The tired business man has a springier step and a keener light in his eye when working in such 

 an atmosphere such is the subtle, scarcely to be observed effect of nature's living plants. 



ness and continuity of bloom. The succession of bloom 

 may be carried out by filling the boxes in the spring with 

 pansies and English daisies, and following these with 

 foliage and flowering plants lasting throughout the summer. 

 The following varieties of annual flowering plants 



are specially suit- 

 able for window 

 gardens : Agera- 

 tum, a compact- 

 growing, hardy 

 ])lant, about one 

 foot in height and 

 producing a con- 

 stant succession 

 of white, light 

 blue, or purple 

 flowers ; Asters, 

 although more 

 easily grown in 

 the open ground 

 than in boxes, and 

 having a short sea- 

 son of bloom, will 

 thrive in the win- 

 dow garden ; Ca- 

 calia, a slender, 

 graceful plant, 

 blooming persist- 

 ently, growing 

 about sixteen 

 inches high and 

 bearing tassel- 

 shaped, bright 

 orange -c o 1 o r ed 

 flowers ; Calendula 

 or M ar i g o 1 d, a 

 rather coarse 

 plant from ten to 

 fourteen inches 

 tall and producing 

 large yellow flow- 

 ers ; Candytuft, a 

 hardy, easily 

 grown plant six to 

 sixteen inches 

 high and bearing 

 abundant clusters 

 of white or purple 

 flowers ; California poppy, an open trailer and a per- 

 sistent though not abundant bloomer; Chinese pink, 

 a persistent bloomer with flowers of brilliant color ; Dian- 

 thus, a brilliant-hued garden pink which is not easily 

 grown, but is so attractive as to warrant the eflfort; 

 Cobelia, a slender-stemmed, delicately graceful plant 

 bearing small, beautiful blue flowers, and very desir- 

 able for the window box because of its graceful habit 

 of growth and constant bloom; Mignonette, one of 

 the most fragrant of our common flowers, and one 

 that does well in the window box ; Nasturtium, an excel-
