1'2G How TO Grow Cut Flowers. 



main in general use save La Prance, and both this and 

 American Beauty need careful handling in order to 

 keep the disease at bay. 



It will have been noticed by those who grow hybrids 

 in the open air, that usually they show comparatively 

 little tendency to take on the disease until late summer 

 or early autumn, then with the heavy dews, cool nights 

 and scorching sun at midday it develops rapidly, oft- 

 times stripping the plants of foliage in a few days. The 

 same conditions, though in less severe form, will have 

 the same effect on both La France and Beauty under 

 glass. I have seen a house of the former ruined in three 

 days, by an over watered bench being exposed for a 

 short time to a sudden change of temperature, though 

 the thermometer did not fall below fifty. This teaches 

 us that the conditions producing this result must be 

 avoided. Another means of prevention is perfect clean ■ 

 liness. Leaves showing the disease should be removed 

 and burned as fast as they appear, thus preventing the 

 spores from maturing and spreading. Having been 

 careful to observe the preventives mentioned, I have 

 not had a serious case of spot for some years, conse- 

 quently have had no occasion to prove the remedies 

 others have advocated, but enumerate them here for 

 the benefit of any who desire to give them a trial. 



Jean Sisley recommends spraying the foliage with a 

 solution of salt water, in the proportion of six pounds 

 of salt to twenty-four gallons of water.
