POTTING. In performing this opera- 

 tion the Pots are the first consideration, 

 and for information relative to these, see 

 FLOWER-POTS. 



Time of Potting. This, when nece^- 

 sary, should generally be done after prun- 

 ing, and when fresh growth has taken 

 place. The reason for this is, that it is 

 advisable never to give more checks to a 

 plant at once than cannot be avoided. 

 The cutting down is a check, the repot- 

 ting or shifting is another. Therefore, 

 in both cases, we apply an extra stimulus 

 for a short time immediately after, by 

 keeping the plants closer and warmer. 



State of the Soil. It should neither be 

 dry nor wet. If very dry, it will not pack 

 so well in the pot ; the water, if it passes 

 freely at all, will find chinks and crannies 

 for itself, and it will be long before the 

 general mass becomes sufficiently moist 

 to support a healthy vegetation. On the 

 other hand, if wet soil is used, it is apt 

 to pack too close ; frequent waterings are
