NO MATTER whether we plant in the spring or 

 in the fall, now is the time to commence the 

 necessary preparations. This is the time to de- 

 cide how man\- trees we need, of what species, where 

 to place them and where 



FALL PLANTING 



For lawn planting the low branching of the tree is a 

 factor, while for street planting the branches should 

 start at about 7 feet from the ground. 



For street planting, it is also important that the stem 



should be perfectly

to purchase them. 



August or September 

 is the best time to visit 

 the nurseries for a per- 

 sonal selection of the 

 plants required for both 

 fall and spring planting. 

 Even if the plants are to 

 be used in the spring, one 

 can have a wider choice 

 oi material if the selec- 

 tion is made at this 

 period and selecting thus 

 early will also prevent 

 delay in delivery at the 

 planting period, especial- 

 ly in the spring, when the 

 pressure of time is very 

 great. 



Xursery-grown trees 

 are preferable for plant- 

 ing to those grown in the 

 forest. The nurseryman 

 in training his trees aims 

 to develop a compact 

 fibrous root, a straight 

 stem, a symmetrical 

 crown and a well-defined 

 leader. Trees grown in 

 a neighboring nursery are 

 better adapted to local 

 soil and climatic condi- 

 tions than those grown 

 great distances away, and 

 transporting them will 

 entail less danger from 

 injury in drying out of 

 the roots and breaking 

 of branches. 



The quality of the trees with relation to local condi- 

 tions is also important. It is important to consider such 

 questions as to whether the plant requires a great deal 

 of moisture or whether it will thrive in poor, sandy soil; 

 whether it will tolerate considerable shade or whether it 

 requires full light.

Early spring, just be- 

 fore growth begins and 

 after the frost is out of 

 the ground, is the best 

 time to plant most trees. 

 From the latter part of 

 March to the early part 

 of May is generally the 

 planting period in the 

 Eastern States. Some 

 consider the fall just as 

 suitable a time to plant 

 as the spring, and with 

 some species and in some 

 localities this is undoubt- 

 edly very true. 



The location of the 

 trees with relation to each 

 other should be carefully 

 considered. On the lawn 

 they should be spread 

 apart far enough for the 

 full development of the 

 crown. On streets trees 

 should be planted 30 to 

 35 feet apart and in case 

 of wide-spreading species 

 like the elm, 40 to 50 feet 

 is not too much. 



HOW TO PLANT 



A HONEY LOCUST 

 A fine tree for an open lawn and for park purposes. 



An abundance of good 

 soil (about 2 cubic yards) 

 is essential with each tree where the specimen used is 

 an inch or two in diameter. A rich mellow loam, such 

 as one finds on the surface of a well-tilled farm, is the 

 ideal soil. Protection of the roots from drying is the 

 chief precaution to be observed during the planting 

 process. Evergreens are more tender to exposure than
