WINDOW GARDENING 



in pots and the roots are becoming matted in 

 the bottom, it is time to shift to larger pots. 

 The condition of the roots may be easily de- 

 termined by turning the plant out of the pot. 

 When ready for shifting the pot selected should 

 be a size or two larger than the old one. 



When the plant is one that has just been lifted 

 from the garden, the pot selected should be 

 sufficiently large to receive the roots without 

 crowding. If any variation from this is neces- 

 sary it is better to have the pot a little smaller 

 than would seem to be required until the plant 

 is well established. 



VALUE OF GOOD DRAINAGE 



One of the essential things in potting is to 

 provide good drainage. By this it is meant 

 that the surplus water must have a chance of 

 escaping easily from the soil. Where the 

 drainage is poor, the excess of water is held in 

 the pot and prevents the air from reaching the 

 roots. The result of this is that the small feed- 

 ing roots are killed, decay follows and extends 

 to the larger roots and growth ceases. Poor
