HOLMES DYNA-GRO’ COMPOST 
Holmes «Fountain of Eternal Youth” for 
Everything in Florida that Bears Leaves, Fruit or Flowers! 
Yes, Holmes Dyna-Gro Compost is sheer magic! It is a 
fortified, amplified, matured, organic, basic plant food 
combination. You put it in at the roots, and it comes out at 
the top. In leaves, fruit, flowers! Not next season, not next 
year, but almost in a matter of days. 
Dyna-Gro is the Secret of Growing Success 
Holmes Dyna-Gro Compost gives you the key to greener, 
darker, glossier leaves; blooms that perk up, gain color bril- 
liance, get larger; fruits that grow quicker, tastier, larger. 
It is the secret of plants of unfailing vigor and vitality, that 
make growth in half the usual time, show up to 14 more foliage, 
stand strong winds and dry spells. 
Dyna-Gro is Scientifically Compounded 
Holmes Dyna-Gro is produced with peat from Holmes own 
beds, then aged for 11 to 30 months while it is fortified with 
added tankage and grassy humus, and turned in huge block- 
long piles to promote bacterial growth essential to plant life. 
The longer the aging, the richer the Dyna-Gro is in plant-food 
value. The combinations of age and fortification have been 
proven in use in our Nursery— proof you can see any day. 
“‘Peat’’ is NOT Enough 
Draw no comparison between “‘peat’’ and Holmes Dyna- 
Gro. We use special tested peat, treated and aged, plus other 
basic plant-food complements. (Peat, as such, is not enough 
to sustain plant vigor; may even be harmful, as we found in 
testing dozens of peat bogs around Tampa that were sterile, 
devoid of bacteria, inert and even salty.) 
Holmes SLeudard DYNA-GRO 
Here’s why it makes things grow. It’s alive with all the 
elements that Nature uses in lush tropical forests and meadow- 
lands. Rich in bacteria, in the by-products of stockyard, 
barnyard and peat bog, mixed and aged, it is disintegrating all 
the time— releasing a continuous flow of the processed organic, 
tankage and vegetable matter we put into it. It needs only 
water to turn it into a “broth” of amazing plant food value. 
Dyna-Gro Compost Has No Imitators 
Maybe all of this sounds simple. Maybe it is. But it took 
us 26 years to figure it out and prove it. And it always takes 
us 11 to 30 months to prepare a “batch” for our customers. 
As of this August, no competitor has yet put into his compost 
what Holmes does. Only Holmes imports car-loads of costly 
tankage (human matter) for compost. Only Holmes “‘in- 
cubates”’ compost for months, ripening it into “‘plant life.” 
1 Week vs. 11 Months 
You can buy so-called “‘compost’’ for less than Holmes 
prices. But not enough less (actually only a few cents a bushel!) 
to get half your money’s worth. The average “compost ped- 
dler”’ offers day-old or week-old raw peat, sometimes with ques- 
tionable additions, that take up to a year in your garden to get 
where you are the day you buy Holmes Dyna-Gro! 
Use Dyna-Gro for Planting, for Re-Invigorating 
Choose the Dyna-Gro grade you need from our three 
distinct measurable qualities—each scientifically fortified, 
aged, mixed. Always mix Dyna-Gro with topsoil when 
planting— then every six months to a year, dig in additional 
quantities for renewed vigor, productiveness. ~*~
