POTTING 



drainage is also the most frequent cause of sour 

 soil in pots. 



HOW DRAINAGE MAY BE SECURED 



There are numerous ways in which good 

 drainage may be secured. Where the plant is 

 a strong grower, all that is necessary is to place 

 a single piece of broken pot over the bottom. 

 This piece should be two or three times the 

 diameter of the opening and should be placed 

 with its concave side down. This prevents the 

 opening from being closed entirely and the 

 water escapes easily under the edges. This 

 method is all that is necessary for three to four 

 inch pots and is usually all that is required for 

 larger pots where the plants have large and 

 strong root systems. Pots from two to three 

 inches in diameter require no drainage, as both 

 the openings and the amount of soil are small. 



The best method to secure perfect drainage 

 and the one that should be used for all slow- 

 growing and woody plants, is to place a frag- 

 ment of an earthenware pot over the bottom as 

 indicated above and then to cover this fragment
