LAMDSCAPE GARDENING 



TREE SURGERY 



A TREE in good thrift, like a person in good health, is practically 

 immune from disease. Hence it is very important that the 

 I ground be kept in good mechanical and chemical condition to produce 

 growth. Plant food must be added to the soil, preferably in the form 

 of animal manure, and, in the case of prolonged drought, water must 

 be supplied. 



But in spite of all our care, trees sometime suffer severe me- 

 chanical injury, such as the breaking of limbs by windstorms, the 

 I rupturing of the bark by horses and, most of all, by improper prun- 

 ing. No one should be permitted to prune trees who does not under- 

 I stand the aseptic cleansing of wounds caused by pruning and who 

 cannot trace the circulation of the sap in the same sense that even 

 children can trace the circulation of the blood. The fact remains, 

 however, that much pruning is done by " tree butchers " and a great 

 deal of mischief results therefrom. 



To remedy this mischief recjuires considerable skill and a thor- 

 ough knowledge of vegetable pathology. I have trained on my own 

 private estate a number of bright young men in the science of tree 

 surgery and the Greening Landscape 

 Company is prepared to vmdertake the 

 renovation of diseased trees. 



The large cut on this page shows 

 an instance where decay followed im- 

 proper pruning. A long stub was left 

 which naturall}^ could not heal. The 

 assimilated sap could not reach it and 

 consecjuently no callus was formed over 

 the wound. In the course of time the 

 stub rotted away, the decay extending 

 deeply into the heart of the tree. We 

 removed all the dead tissue, and after 

 making the cavity chemically clean it 

 was filled with a cement preparation 

 that is impervious to water. In a few 

 years it will heal over and leave no trace 

 of injury. The small cut shows the body 

 of a maple tree that had received much 

 abuse. Our treatment saved it and it 

 is now in good thrift.
