surface of the beds about every five or six 

 weeks during the growing season. 



Dr. A. B. Griffiths recommended, in his 

 " Special Manures for Garden Crops/' a 

 chemical manure composed of one-half ounce 

 of superphosphate of lime, and one-quarter 

 ounce each of iron sulphate and sulphate of 

 ammonia. These quantities were to be put 

 into two gallons of water, and the liquid 

 applied to the roots without wetting the 

 foliage. In "The Book of the Rose" (third 

 edition), the Rev. A. Foster-Melliar states that 

 sulphate of iron is said to give a better colour 

 to the foliage, and in some sorts, such as Anna 

 Olivier, to the blooms as well, but he does 

 not place much reliance upon this. He recom- 

 mends the following mixture, as prescribed 

 by Mr. Tonks upon the result of analysis of 

 the ash left from the burning of rose plants: 



Superphosphate of lime 12 parts 



Nitrate of potash 10 



Sulphate of magnesia 2 



Sulphate of iron I 



Sulphate of lime 8

This mixture should be applied in March 

 and scattered over the previously hoed surface
