How scientific Tree Surgery enables the 

 gardener and estate manager to combat them

DECAY is caused by the sfore: 

 of disease fungi and is often 

 hidden from the untrained eye. 

 The tree in the picture wa-s 

 apparently sound, bnt was 

 fyund to have a ca~Aty extend- 

 ing 25 feet up the trunk! The 

 Davey method of scientific 

 treatment, sectional filling and 

 mechanical bracing is the 

 ONLY way to prevent certain 

 premature death from decay. 



IMPROPER PRUniNG. leav- 

 ing the e.rposed stub open_ to 

 the attacks of disease fungi, is 

 sure to result in decay zvhich 

 cats progressively into the 

 trunk. Long experience and 

 scicntiHc training have taught 

 tlie Davey Tree Surgeons how 

 to make this operation a per- 

 manent success in ez-ery case. 

 Daveyite, the best wound 

 dressing ez'er produced, is 

 used to protect the zvounds. 



Here are shown live of the most common causes why 

 trees die prematurely. Each is, or results in, a condi- 

 tion that works progressively toward the destruction of 

 tree life. Unless checked in time, each is certain to be 

 fatal to the most vigorous tree. 



Gardeners and estate managers cannot be expected to 

 know how to combat them. Tree Surgery is an exacting 

 science requiring special training and experience. A 

 Tree Surgeon is a specialist. You employ him as such. 

 The Davey organization offers you the best in Tree 

 Surgery — scientific accuracy, mechanical perfection, 

 operators of finished skill. Every Davey Tree Surgeon 

 must conclusively demonstrate his fitness before he is 

 allowed the least responsibility. 



Davey Tree Surgeons are the only Tree Surgeons that are 

 backed by a successful, responsible house, amply able to 

 make good in every instance ; the only tree Surgeons 

 officially regarded as good enough to be employed by the 

 United States Government. 



A generation of successful practice upon thousands of 

 America's estates testifies to the worth of Davey Tree 

 Surgery. It is the only safe Tree Surgery that you 

 can employ in the care of trees upon your estate. A care- 

 ful examination of your trees will be made by appointment.

Mauv trees die of hunger, thirst, or smothered roots. 

 If the top oi a tree is dying back, this is positive iiidi- 

 eation of serious trouble with the roots. Quick action 

 is then essential. Davey Tree Surgeons, if siven half 

 a chance, can save trees so threatened by applying 

 established Principles of fertilizing and root irrigation. 

 Action, hoTi'ev.Ci-, must be taken at first sign of danger. 



IMPROPER TRIMMING, in- 

 cluding the use t f climbing 

 spnrs, C'juses countless little 

 injuries that rapidly grow into 

 serious menaces. Davey Tree 

 Surgei ns use re pes and lad- 

 ders in trimming and exercise 

 the greatest care in all tree 

 work. Davey Tree Surgeons 

 respect the tree as a liz'ing 

 thing and protect it from 

 harm xvhile < perating on it. 



THE V'SHAPED CROTCH is 

 a -weakness of 75% of all shade 

 and fruit trees. A tree of this 

 tvpe is structurally weak, likely 

 to split apart in any high wind, 

 a7id open to the ravages of de- 

 cay. A V-shaped crotch means 

 certain ruin sooner or later, if 

 neglected. Only the Davey 

 system of scientific mechanical 

 bracing, and, where necessary, 

 treatment for decay, can save 

 a tree so afflicted.
