THE GREEN-HOUSE. 



contains is easily exhausted ; but some plants require 

 it more frequently than others, from the nature of 

 their roots and their habits of growth. Plants that 

 transpire freely, as the Geranidcece and Scitaminece, 

 require more frequent renewals of mould, than such 

 as have few pores on their surface, as the Ericece, 

 Succulents, &c. The reason is sufficiently obvious ; 

 the former orders of plants requiring much larger 

 supplies of water than the other. 



No garden, however small, which contains a green- 

 house, or pits and frames, can be without a shed for 

 holding tools, pots, and other articles ; and in this 

 shed there is generally a table or bench for shifting, 

 and for other operations with plants in pots. Prepa- 

 ratory to shifting, there should be a quantity of dif- 

 ferent-sized pots looked out and cleaned, and sherds 

 or pieces of broken pots prepared for covering the 

 holes in their bottoms ; next, some loam, peat, sand, 

 and vegetable mould should be sifted, and laid on 

 heaps on the back part of the bench ; and at hand in 

 the shed there should be a pot or two of gravel for 

 covering the bottoms of some pots, in addition to 

 the sherds or crocks, some lime-rubbish, props, and 

 ties, &c. 



About the middle or end of May, the operation 

 may be commenced, by removing a few plants from 

 one end of the stage to the shed. Then taking one 

 of the pots, proceed to turn the plant out of it with 

 the ball of earth entire, by turning the pot upside 

 down, and striking the edge of the pot against the
