Gro=Mulch 
Shrubs 
Most shrubs are not especially particular about the composition 
of the soil, but since the plants will be in their station for a long 
time, 10 to 15 pounds of Gro-Mulch should be worked well into the 
soil. Later applications should be added as a mulch as the shrub 
increases in size. 
AZALEAS 
This is a shallow rooted plant, therefore mix the Gro-Mulch in 
the top four-to-six inches of soil at setting time. After setting, add 
two inches of Gro-Mulch on the surface of the soil as a mulch to 
protect these shallow roots from heat and drouth. No fertilizer is 
necessary, for Gro-Mulch gives off enough organic acid for the acidic 
needs of Azaleas. 
ROSES 
If roses are to flourish, they must have plenty of organic matter, 
moisture, sunlight, and good drainage. Three inches of Gro-Mulch 
worked well into the top 12 inches of soil will supply sufficient 
organic matter, and plant food; and will aid porosity of the soil 
sufficient for good aeration and moisture holding capacity. A one- 
inch mulch is advisable on the surface of the rose bed during any 
hot and dry periods. 
CAMELLIAS 
These plants will grow in quite poor soil provided it is of a 
somewhat acid character. They are, however, very slow growers 
unless well cultivated, mulched, and fed. No less than 15 pounds of 
Gro-Mulch should be pulverized within the soil when the camellia 
is set in the yard. A two-inch mulch then maintained will keep the 
roots cool and moist and will liberate sufficient acid and plant 
nutrients for very vigorous and fruitful plant growth. 


LETTER FROM MISS CAROLINE DORMON 
Saline, La. 
Magnolia State Nursery 
Baton Rouge, La. 
Dear Mr. Harper: 
You remember that sack of “material” (I believe you now 
call it “Grow-Mulch’’) that you brought me last year to try? Well, 
it is really the stuff. | worked it in around some of my fine Louisiana 
iris seedlings, and they are about three times as fine as those that 
did not have it. It is certainly a “natural’’ for these irises. 
I had some special daylilies that Geddes Douglas had sent me 
from Nashville. I used the Gro-Mulch around these, and they bloomed 
beautifully, and how they have multiplied! 
You know how cantankerous native deciduous magnolias are, 
and what voracious feeders they are. I used Grow-Mulch around 
two, with a tiny bit of crushed lime-rock, and a little phosphate 
fertilizer, and they are thriving. 
I don’t go in for camellias (as you know, I have mostly native 
plants), but my sister has two. They had never bloomed much— 
just a blossom or two on each plant. Grow-Mulch made them bloom 
—at least, they are now covered with buds. 
As you told me you folk were testing out the Gro-Mulch, | 
thought you would like to have this report. I believe it will benefit 
any and all plants, as it both mulches and fertilizes. 
Sincerely yours, 
CAROLINE DORMON
