DRAINAGE 



soil washes down it will settle and close the 

 opening about the piece, and the first thing 

 you know your soil will be like mud, because 

 there is no chance for the water to escape. 

 Always plan to keep this hole free from 

 obstructions. It is a good practice to turn bot- 

 tom side up, occasionally, and make sure, by 

 the finger, or a stick, that this hole is not 

 clogged up. 



In order to prevent the soil from washing 

 down and filling the crevices in the drainage, 

 a layer of sphagnum moss should be spread 

 over it before any soil is put into the pot. 

 This is important. If moss can not be ob- 

 tained, use a thin piece of sod, grass-side 

 down. Moss, however, is much preferable, 

 as it does not easily decay under the action of 

 water.
