PLANT PROPAGATION 



85. Flower pots are of two principal kinds ; those 

 with and those without rims. They range in one-half-inch 

 sizes between two and seven inches, and in one-inch sizes be- 

 tween 7 and 12 inches. Between two and two and one- 

 half is a two and one-fourth-inch size. There are also 14, 

 16, and 18-inch sizes, but tubs and boxes are usually more 

 satisfactory and less expensive in these and larger ones. 

 Sizes below 16-inch are machine made in "standard" form. 

 Straight-sided pots are little seen nowadays. Below the 

 two-inch size are "thumbs" used for tiny plants. 



Azalea or three-fourth pots are most useful for growing 

 ferns, azaleas and other house plants, lilies and many other 

 bulbs. They afford ample soil and root room, are not 



as unsightly as full-sized 

 flower pots of the same 

 width. Their "low 

 clown" effect is more 

 pleasing to the eye than 

 is that of the tall pot. 



"Seed pans" are earth- 

 enware trays usually one 

 to two inches deep. They

 plants, etc. For this purpose they excel pots. 



The rimmed or "standard" pots (Fig. 21), though 

 easier to grasp are harder on the hands than are those 

 without collars when large numbers must be handled 

 in a day, yet they are so popular that the old style col- 

 larless ones are almost a curiosity in many sections of 

 the country. Whichever style is chosen, it should be 

 porous, never glazed. When to be first used, the pots 

 should be dipped in water a few minutes and the surface 

 water then allowed to evaporate. The pores of the pot- 

 tery must be filled with water but the pots must not 

 be wet when plants are set in them
