The Florists^ Review 



Jandart 16, 1920. 



"Master Soil Builders" 



The average greenhouse man is confronted with 

 a serious and insistent problem in the matter of a 

 supply of animal manures. Not only are manures 

 becoming extremely scarce and high in price, but, 

 when obtainable, they are under the ban of boards 

 of health and other public authorities. Rail trans- 

 portation, cartage and storage often are forbidden. 



And yet the grower must have plant food — it 

 must be effective and economical, simple and safe, 



and it must be in unfailing supply, acceptable to the 

 transportation companies, the health authorities and 

 the neighbors. 



But the place of the rapidly disappearing and 

 offensive raw manures will now be taken by "Master 

 Brand" Vine and Plant Manure. It is successfully 

 used by large numbers of florists and it will be gen- 

 erally adopted now that we have so increased our 

 facilities and production that we can supply the 

 trade in unfailing quantity. 



"MASTER BRAND" 

 CONCENTRATED VINE AND PLANT MANURE 



Guaranteed analysis: 5% ammonia, 2% phosphoric acid, 1% potash 



In oflfering "Master Brand" Vine and Plant Manure to 

 florists and gardeners we have put on the market an abso- 

 lutely pure manure product made up from the most power- 

 ful of animal and poultry manures, thoroughly sterilized 

 and scientifically mixed without any loss of the essential 

 plant food elements — in no way has the manurial value of 

 the organic matter of which it is composed been impaired. 



"Master Brand" Vine and Plant Manure supplies at rea- 

 sonable cost a natural plant food and soil builder that is 

 more efficient than any of the imported plant foods that 

 are so highly esteemed by professional gardeners. 



No capable grower can fail to produce profitable crops 

 if he feeds them with "Master Brand" Vine and Plant 

 Manure in connection with his usual good culture. This 

 soil builder and plant food is equally adaptable for feeding 

 outdoor and greenhouse crops. It is particularly valuable 

 as a top dressing or liquid food for roses, carnations, chry- 



santhemums and the general list of decorative and flower- 

 ing plants grown under glass. 



For feeding the general list of greenhouse bench plants 

 75 to 100 pounds for each 500 square feet of bench surface 

 is sufficient for one application of top dressing. The fre- 

 quency of application depends on the condition of the 

 plants and time of year, but in general the treatment would 

 be the same as with any high class manure. For potting 

 soil use a 5-inch or 6-inch pot of "Master Brand" Vine and 

 Plant Manure to each wheelbarrow load of soil. 



"Master Brand" Vine and Plant Manure is guaranteed 

 to be a pure animal manure product, thoroughly sterilized 

 and packed in burlap bags containing 50 pounds and 100 

 pounds, net weight. 



Send a trial order, or write for the names of well pleased 

 users, descriptive circulars and prices.

 Manure of guaranteed analysis.
