or young plants during the winter, is to keep them the whole 

 summer in the pots, in which they are first struck, plunging 

 them out in the borders. When taken up in the autumn they 

 are still to be retained in the pots, which being cleaned and 

 dried, may be stored in a cellar or other place into which the 

 frost will not penetrate. The roots thus treated, when taken 

 out in the spring, are in excellent condition, and the earth 

 being shaken off them, they are to be re-potted in the same 

 manner as is usual for older roots. 



The method of propagating Double Dahlias by engrafting 

 them upon the roots of single kinds, as described by Mr. 

 Thomas Blake, in the fourth Volume of these Transactions, 

 page 476, is not now much practised, it being found more con- 

 venient to propagate them from cuttings, which, if properly 

 managed, produce plants equally vigorous, with less trouble.
