Insects, decay, wind, ice, and civilization are frequently enemies of trees. When one or 
more of them attack a tree, that tree becomes just as unhealthy as an animal with an 
ailment. If the tree is situated in a deep woods or forest, little thought is given to its sur- 
vival—but if it happens to be on your lawn it becomes much more valuable, and almost 
any care it needs is justified. 
FIVE REASONS WHY TREES DIE 
ROT AND DECAY 
Decay eats out the heart wood, destroying the circulating system of trees, and often makes 
them unsafe. 
BROKEN AND DEAD BRANCHES 
Are unsafe, unsightly, and invite insects, pests and decay. 
STARVATION 
Undernourishment weakens, and in extreme cases kills trees. 
INSECTS AND DISEASE 
Sap the strength, and sometimes completely defoliates them. 
MAN, WEATHER, AND ACCIDENTS 
These cause the death of many fine trees. 
Further details of these ailments and their cures will be found on the following pages. 
The Tree Expert Department of Swain Nelson & Sons Co. is composed of an exception- 
ally fine group of tree specialists. By giving them an opportunity to inspect the trees on 
your grounds (which will cost you nothing) you will be able to know definitely the condi- 
tion of your trees.
