176 Care in Planting Irees 
or specimens, and especially with smaller-sized plant mate- 
rial, less care will still produce satisfactory results. The 
experienced tree planter will know how far under given 
conditions he may neglect the precautions. The forester 
who plants by the thousand or million cannot afford to ob- 
serve all the rules, but then he does not expect to have all 
his trees live. Planting perhaps twenty-five to thirty per 
cent. more than he expects to start, and ten times as many 
as will survive until harvest time, and choosing young small 
plant material, he reduces the need of attention to the 
details. The planter of street and lawn trees, however, 
who desires each tree to live will be the more successful the 
closer he follows the details and the spirit of the ideal method 
described. 
The question as to proper dime for transplanting has been 
discussed ever since the age of the Greeks and Romans. 
Theoretically speaking, trees may be transplanted any day 
in the year, if the proper precautions are taken, but prac- 
tically, it wi ell to choose ati the least care 
is needed,z¢., during the period when vegetation is at rest, 
fall, winter, or early spring. 
Considerations of weather may influence the choice in 
different localities: in regions with well-marked spring and 
summer rains, spring Is the best time; in regions with dry 
spring and rainy autumn, fall planting is indicated, misty 
or rainy days are, of course, most favorable, except possibly 
in_compact clay soils. 
Physiological reasons make it desirable to choose a time 
when, shortly after planting, root growth is most active. 
This consideration would indicate the fall as the most fav- 
orable season for deciduous trees, since with them root 
growth continues into the winter, and besides, the absence 
of transpiring foliage avoids a drain of moisture such as is
