food. 
Yes, there is only one Vigoro—the finest you can feed. 
And that’s because Vigoro provides not just one or 
three or five, but all the food elements needed to 
supply the complete nourishment grass requires 
for the fullest, finest top and root growth. In 
fact, Vigoro has been proved to be so complete 
it can make grass grow and thrive even in plain sand! 
See what a difference it makes on your lawn. 
The picture at right shows the results of 
a test made with Beets growing in sterile 
sand. The one fine Beet received all the ele- 
ments whereas each of the others received 
all but one. Here is photographic proof 
that plant feeding, more than any other 
factor except good seed, determines the 
success of the gardener. 
INCLUDE VIGORO 
IN YOUR SEED ORDER! 
Use a Vigoro spreader.
