TREATMENT OF TENDER AND RARE ALPINES. 5? 



this can be accomplished, suitable places for their 

 culture must be attended to. 



As to the hardier tribes of Alpines, wooden shut- 

 ters are quite sufficient, although for successive days 

 they may be covered up or in the dark ; during 

 winter it does no harm, they being then in a torpid 

 state, and resembles what they are accustomed to in 

 their native abodes, at that season enveloped in a 

 mantle of snow. The only reason for uncovering 

 them, or taking off the wooden sashes, every fine 

 day in winter, is simply to assist in drying up 

 damp, and clearing away any thing in a state of 

 decay ; during the rest of the season, the sashes 

 can be taken off during the day, or entirely removed. 

 I have seen both used, but would not say that glazed 

 ones are in any degree preferable to wooden ones, 

 in regard to their culture.* 



In the culture of this group that we are treating 

 of, they require large pots, Nos. 24 and 16, the 

 former are 8 inches deep and 8J diameter, the 

 latter 9 inches deep and 9 diameter ; in some 

 instances, the roots penetrate deep, and when this 

 is not the case, the plants are sometimes of a 

 spreading nature, consequently requiring room, a 

 good depth of soil and moisture. 



Regarding the potting and shifting of these, it 

 may be performed in January or beginning of the 



* Now that the heavy duty on glass has been abolished, glazed 

 sashes will, doubtless, be generally adopted.
