CULTIVATION 



down the long trailing branches carefully and cover 

 them with earth. This should especially be done in 

 the case of climbing Hybrid Teas, as these kill back 

 very much more than the other climbers. 



RECIPES FOR THE DISEASES OF ROSES 



Below we quote extracts from the best known 

 authorities, giving their recipes for mildew, black 

 spot, rust, etc. 



"THE ROSE BOOK" (Page 211). H. H. THOMAS suggests using a 

 mixture for mildew of equal parts of fine quicklime and sulphur 

 dusted on the affected areas. 



"ROSES, THEIR HISTORY, DEVELOPMENT, AND CULTURE" (Page 

 303). PEMBERTON advocates the same dusting and also gives the 

 following: 1 Ib. flowers of sulphur, 1 Ib. powdered quicklime. 

 Add sufficient water to form a paste. Add one gallon of cold 

 water. Boil for twenty minutes and when cool pour off the 

 liquid and spray at the rate of half a pint of the above mixture 

 to six gallons of water. 



(Page 303). PEMBERTON recommends 1 Yi Ib. of Calvert's carbolic 

 soft soap in 7^2 quarts of water a pailful; spray with one part 

 of mixture to three parts of soft water, and he adds, "this is 

 the remedy we apply." 



" ROSES AND ROSE GROWING" (The Macmillan Co.), (Pages 137- 

 138). Miss KINGSLEY advocates flowers of sulphur for mildew, 

 distributed by a pair of powder bellows, and suggests applying 

 before mildew appears. She uses Quassia Chips for Aphis, and 

 recommends picking by hand for caterpillars. 



"THE ROSE" (Page 89). ELLWANGER'S recipe for mildew is sulphur 

 and soot, applied while the dew is on the plants so that it will 

 adhere. 



" ROSES" (Page 52). The Garden Library of Doubleday, Page & 

 Company suggests for black spot carbonate of copper com- 

 pound, using five ounces of copper compound to three quarts 

 of ammonia and sixty gallons of water. The spraying should 

 be done once a week, using a hose with a nozzle that gives a 

 fine spray. 



"PICTORIAL PRACTICAL ROSE GROWING" (Pages 80-84). WRIGHT 

 does not mention black spot, but our understanding of the 

 reference made to orange fungus or red rust is that it develops 

 into black rust, possibly the same as the well-known black spot. 

 This article is so clear and appeals to us so strongly that we 

 quote it verbatim, and will try the recipes given if troubled in 

 the future.
