176 PRACTICAL PLANT PROPAGATION 



ANNUALS 



Annuals are plants which live but one year, the seed is sown, the 

 plants bloom and seed all in one year. There are three classes of an- 

 nuals according to their culture: Hardy, tender and hah" hardy. 



Hardy annuals are usually sown where they are to grow, as early as 

 the soil can be worked. They often self-sow, such annuals may, there- 

 fore, be sown in the Fall if one prefers. 



Tender annuals will tolerate neither the cold soil of early Spring, the 

 freezes of Winter, nor the slight frosts of the Fall. The seeds of such 

 sorts must be sown indoors from January to May or in the open soil 

 when the ground is warm. 



Half hardy annuals, though often hardy enough, have a long grow- 

 ing season and do not reach their proper development unless sown in the 

 greenhouse, hotbed or coldframe in March. 



Some annuals, especially the Pea-, Poppy- and Melon-like sorts, 

 those with taproots principally, are difficult to transplant. Either 

 sow the seeds in thumb pots or in their permanent quarters. In the 

 case of the other annuals transplanting is beneficial, in that the roots 

 slightly broken are induced to branch making the plants stocky and 

 more easily transplanted in the future.
