Combat Unnatural 
Conditions 
In their natural habitat trees are kept in 
vigorous condition by ‘’Nature’s Food’’— 
decayed leaves, grasses and other vege- 
tation furnish materials for strong growth. 
Trees near buildings, in lawns, gardens 
and along paved streeets, do not have 
these natural sources of food. Feeding is, 
therefore, often necessary. 

Feeding mature trees keeps them 
healthy and more resistant to disease— 
foliage looks more luxuriant because the 
leaves are larger in size and a deeper 
green. 
Regular feeding of small trees can dou- 
ble the rate of growth and saves years of 
time waiting for them to grow.

Spraying Aids Gontrel 
of Insect Posts 
Out of thousands of insects which at- 
tack trees, two broad classifications may 
be successfully controlled by spraying. 
SAP SUCKING INSECTS which work on 
twigs, branches and leaves. Many of 
these are small, and it is difficult to see 
them with the naked eye. These pests 
undermine the health of trees, and in time 
kill them. 
LEAF EATING INSECTS are numerous 
in variety and capable of partially or en- 
tirely defoliating trees. 
The trained Tree Expert is able to rec- 
ognize the attacking insects and prescribe 
the time and material for spraying them. 
Swain Nelson Tree Experts possess spe- 
cial, powerful equipment which effectively 
sprays even the topmost branches, thor- 
oughly and economically.
