Proved Results in Cultivating and Regenerating Orchards: 



1. Young spade-set trees can be forwarded in development at 

 least a year by dynamite blasting between the rows. 



2. Old, failing trees can be restored to ample productiveness by 

 blasting between the rows. 



3. Fungus diseases can be eliminated by blasting under affected 

 trees, or blowing out those killed by fungus, and planting new trees in 

 their places. 



Cultivate Spade-set Trees With Dynamite 



We frequently receive letters from orchardists stating that they had 

 planted trees in their orchards a year, two years or three years ago which 

 are not doing well because of hardpan conditions beneath the surface soil or 

 because of compacted soil or insufficient moisture storage capacity of soil. 

 These orchardists express the keenest regret at having learned about tree 

 planting with dynamite after their orchards had been planted. They tell us 

 they believe their trees would be in a much better condition had they been 

 planted by this method. 



f If their trees are alive, there is no occasion for repining. The subsoil in 

 which the trees are planted can still be broken up by subsoil blasting between 

 the trees. This rejuvenation work will give the trees the same favorable 

 opportunity for growth and development that they would have had had they 

 been planted in holes prepared by dynamite blasting in the first place. 



Millions of fruit, shade and ornamental trees are standing in the orchards, 

 parks, yards and along highways in this country. Many of them are very 

 valuable because of the fruit they are capable of producing. Others are 

 highly prized by their owners because they serve to ornament and shade 

 residence properties or parks ; others add greatly to the appearance of streets. 



But many of these trees are in an unhealthy condition. This may be due 

 to various causes. An investigation will show that soil conditions are at 

 fault as often as any other cause. Many of these soil conditions may be 

 remedied by subsoil blasting between the trees. If the soil in which the tree 

 is planted is compacted so that it is difficult for the roots to make healthy 

 growth into the deep subsoil, or if the soil is not sufficiently porous to permit 

 of the absorption and storage of moisture, blasting with dynamite will prove 

 an effective remedy. 



In every part of the United States will be found trees in parks and along 

 public highways showing signs of deterioration. Sometimes these conditions 

 are due to the fact that the trees are planted in poor soil; sometimes because 

 they are in soil underlaid with hardpan or compact subsoil ; sometimes because 

 their roots grow out under asphalt, cement or flag pavements which pre- 

 vent them from obtaining the benefit of rainfall. In any of these cases the 

 use of dynamite will improve the health of the tree. 



The Park Commissioners at St. Louis and Joplin, Mo., and Los Angeles 

 and San Diego, Cal., have recently used dynamite for these purposes with 

 excellent results. In St. Louis 200 trees were planted at a cost less than the 

 work could have been done by labor alone. 



Mr. Kieth, a Park Commissioner of Joplin, Mo., is a member of the 

 National Park Association and intends making a report to the Association of 

 the results obtained in his city. His experience in planting walnut and black 

 locust trees was such that he says he will always plant trees with Du Pont 

 dynamite hereafter. 



Rejuvenation of Trees Within City Limits 



Every old town has many trees along the streets that are failing, from one cause or another, 

 but mostly from root cutting on streets where sidewalks have been laid, cutting off their former 

 supply of nourishment. In this contracted space the tree soon exhausts what little fertility is 

 within easy reach. 



Many an old dying tree have I resuscitated by a half dozen small charges of dynamite 

 below the root system, often filling the hole after the charge is in with some fertilizer which 

 will be scattered through the soil close by the roots, giving them the immediate effect. 



I use this same method in orchard dynamiting and it works wonders. Often the effect can 

 be seen in ten days after treatment. M. J. WALTERS,
