Mildew. This affects many plants which are " below 

 par." Flowers of sulphur is one of the remedies. The 

 affected plants (roses, chrysanthemums, etc.) should be 

 dusted over with it, and the affected leaves may be picked 

 off and burnt. Another way is to spray them with a 

 solution of one ounce of potassium sulphide dissolved in 

 two or three gallons of water. 



It is well to keep a watchful eye on roses, chrysanthemums, 

 and hollyhocks for the appearance of any of these diseases. 

 As soon as they appear apply the remedies. Do not wait 

 till the plants become badly affected, or they may all be 

 ruined. 



If by accident a plant does get very badly affected, do 

 not hesitate to pull it up and burn it at once to prevent 

 the disease spreading.
