ORNAMENTAL PLANTING OF TREES AND SHRUBS 119 



All such pruning should be done carefully, making the cuts 

 clean and close up to a bud or stem, so that no stubs remain to die 

 back and cause injury. Hard wooded trees such as the Oaks and 

 Hickories must be cut back hard as they are apt to have fewer feed- 

 ing roots than the softer wooded trees. Do not waste time and 

 material on a poor specimen. Secure good, healthy trees with good 

 root system and, if possible, trees that have been frequently trans- 

 planted. 



TREE PLANTING WITH DYNAMITE 



The blowing of tree holes with dynamite is to be recommended 

 from the standpoint of economy alone. A good, big tree hole is 

 much more easily dug if the ground has first been loosened with 

 d5mamite. 



The loosening of the soil aids root growth and affords easy pene- 

 tration of moisture to the root feeding areas. 



One-half a stick of forty per cent, dynamite is usually sufficient 

 for a hole. 



One thing to avoid in planting trees in dynamited holes is the 

 pot hole (Fig. Ill), formed by the gases at the time of the explosion. 

 Holes are not dug deeply enough after the explosion and this hole 

 is allowed to remain. After a few rains have loosened the soil above 

 it drops down to fill up the hole, leaving roots uncovered, often 

 resulting in the loss of the tree. All dynamited holes should be gone 

 over carefully with a long pole or bar so that the earth will settle 

 into any deep holes that may have been formed. 



MOVING LARGE TREES 



On new estates quick results are often desired and may be secured 

 by the planting of large specimen trees (Fig. 112). 



The same principles apply to the moving of these large specimens 

 as apply in all instances of tree transplanting. The trees must be 

 carefully dug, preserving the small feeding roots even though they 

 extend for a distance of from fifteen to twenty feet away from the 

 trunk. As these are uncovered they should be tied up in bundles 

 and bent out of the way, and protected with straw or burlap care- 

 fully wrapped around the roots. 



If the trees are very large and heavy special apparatus must be 

 secured for their proper handling.
