146 GEEENHOUSE MANAQEMENT. 



become dry. Keep the moisture off the leaves as much 

 as possible. As soon as the roots fill the pots after the 

 final shift, supply manure water liberally, but disoon- 

 fcinue its use when the fiovvers begin to open. 



In addition to the plentiful use of tobacco stems 

 upon the greenhouse benches, to keep the aphis in 

 check, frequent light fumigations should be given. 

 To avoid disease, keep the leaves dry, and at once 

 remove and destroy all diseased and decaying leaves. 

 With careful management, the greenhouse can be kept 

 in a blaze of color from January until the middle of 

 May, and fiorists will find a growing demand for cal- 

 ceolarias as house plants. 



CINERARIAS. 



The greenhouse cineraria occupies about the same 

 place, both in the conservatory and the house, as the 

 calceolaria, and it flowers at about the same time. The 

 single forms are of little value for cut flowers, but some 

 of the double kinds may become useful. The cineraria 

 is even more injured than the calceolaria by a hot, dry 

 air, and a slight frost that might not affect the calceo- 

 laria would prove very injurious, if not fatal, to it. 

 Like that plant, its greatest enemy is the green fly, but 

 the principal reliance must be placed on the chopped 

 tobacco stems, or the vapor from tobacco tea, or extract, 

 as tobacco smoke, unless in a mild form, affects the 

 foliage. Unlike the calceolaria, the cineraria delights in 

 water upon its leaves and on every bright morning, even 

 in winter, the plants should be syringed. 



In a general way, its care is the same as given for 

 the calceolaria, and may be briefly stated as follows : 

 Sow the seeds in shallow pans, from June to August ; 

 prick out the young plants in flats or pots, and later 

 transfer to three-inch pots, repotting, before growth is 

 checked, into five- or six-inch pots. Sometimes they can
