YOU CAN ACHIEVE / 
RICH GARDEN BEAUTY/ 
This plant feeding test reported in U. S. Department of Agriculture Bulletin 340 lets you see 
why you get wonderful results from Vigoro. Plants I to 5 and 7 to 10 were fed all necessary 
elements except one, as noted. Plant 6 received all elements. Vigoro supplies plants 
with all elements they must gel from the soil. 
You can grow beautiful lawns and flowers as pictured in this catalog. Disappointments 
are most often the result of half-starving or improperly feeding your plants. 
Assure success by giving everything you 
grow a square meal of VIGORO. 
Vigoro is different! It is a complete plant 
food that contains all of the elements plants 
must get from the soil instantly ready for 
the plant’s use. Bone meal, manures, and 
sewage supply only one, two, or at most three 
elements and these must first be released 
for use by decay, a process that’s slow in 
spring when plants need food most.
