and state that all greenhouse plants should be shifted at least once a year, 

 many of them oftener, according to their habits of growth or the purpose 

 for which they may be intended. There is one very general and very 

 great fault in shifting plants, and that is, placing them in too large pots, 

 nor is this a subject that any written directions can explain or rectify. 

 We know of no other rule that can be at all considered as bearing on the 

 case, or that we have words to explain, other than proportioning the size 

 of the pot to the number, size, and form of the roots. Thus a heath, or 

 Azalea, requires a much less pot to grow in than a Pseonia or Fuchsia 

 of the same size, and such plants as Chrysanthemum, Calceolaria, &c., that 

 require to be grown rapidly to increase the number and size of their 

 flowers, and also those being only herbaceous, that is, producing a fresh 

 volume of herb annually, require much larger pots than the slender-rooted 

 Selago, or Chi'ronia, Instead of calculating by the size, number, or nature 

 of the roots, it is too general a practice to calculate by the size of the 

 plant only. 



AZALEA. 



The Chinese varieties of this splendid genus strike by cuttings of the 

 young wood taken off close to the ripened shoots, planted in sand, and 

 placed under a bell-glass in a mild bottom heat. The best soil for grown 

 up plants is a sandy turfy peat, and the best situation the most sunny 

 while in the greenhouse, till after they flower, when they may be placed 

 out of doors, but not in an exposed place. They must be kept in a cool 

 pit during winter, and taken into the house in February or March, to 

 produce their flowers. 



INDIGOFERA. 



This genus seeds freely, from whence young plants may be obtained, 

 the seeds to be sown as soon as ripe. They also increase by cuttings, 

 planted in sand and placed in a cool situation. The best soil for them is 

 light sandy loam and peat, the larger proportion of the latter. 



PIMELEA. 



Cuttings of the young wood root freely, planted in sand and placed 

 upon a shght warmth without bell-glasses. They often seed afeimdantly, 

 and in this case should be sown in fine sandy peat soil, slightly covered, 

 and placed in a cool situation near the glass. Sandy peat with a portion 

 of vegetable fibre is the best soil for them.
