SEEDING AND PLANTING 



ball attached removed one at a time as wanted for planting or 

 else in the case of special receptacles, each of which contains but 

 a single plant, the receptacle itself with the contained plant is set 

 in the soil at the proper depth. In the latter case, the receptacle 

 must be of such a character that it will readily disintegrate and 

 not interfere with the later development of the plant. 



6. Planting Balled Stock. As a general rule, the upper 

 part of the ball should be level with the surface of the soil 

 when the tree is set. When the planting 

 '-^-H^ hole is of the same size and form as the ball 

 no adjustment is necessary in order to attain 

 this end. It is necessary only to press the 

 ball into place firmly. When the planting 

 hole is larger and of different size than the 

 ball, as the earth is filled in, the tree should 

 be carefully adjusted to the proper position. 

 The soil should be thoroughly tamped in 

 order to fill all spaces between the ball and 

 the sides of the hole. 



7. Lifting and Planting Balled Plants with 

 Special Tools. Dr. Carl Heyer 1 devised the 

 method of lifting and planting small and 

 medium-sized plants by means of a cylindri- 

 cal or hollow spade (Fig. 112). This spade 

 is made in various sizes varying from 2 to 6 

 inches in diameter at the cutting edge and from 

 one-eighth to one-fifth larger at the upper end. 

 It is not practical, however, for lifting plants 



with balls of earth more than 5 inches in

drical spade. diameter as the ball will not remain in the 



spade when it is withdrawn from the soil. It 

 can be used only in lifting plants that are sufficiently wide-spaced 

 to permit its use without interfering with adjacent trees, e.g., in 

 lifting 2-inch balls the plants should be at least 3 inches apart, 

 and in lifting plants with 5-inch balls the plants should be 

 6 inches apart. 



In operation, the cylindrical spade is placed over the tree to 

 be removed with the stem in the center. It is then thrust verti-
