296 FLOWER GARDEN. 



earth or leaf-mould, and one-half pure sand. Their 

 growth is expedited at first by gentle heat. In about a 

 month they are found to be rooted, and are placed in 

 a cold frame, in which they are kept till the beginning 

 of June, when they are put into larger pots, and set out 

 in some airy situation. About this time, the tops of the 

 plants are pinched off to make them bushy, but no more 

 side shoots are allowed to remain for flowering than the 

 plants are likely to be able to support without a stake. 

 In August, they are again shifted into larger pots, filled 

 with strong rich soil. During the whole season, the 

 pots are frequently moved to prevent the roots from 

 striking through, and they are never plunged. Mr. 

 Munro, of the London Horticultural Garden, whose me- 

 thod of culture we -have been describing, recommends 

 liquid manure to be applied from time to time in sum- 

 mer and autumn. Other cultivators, in order to have a 

 greater succession of flowers, and a- variety in the sta- 

 ture of the plants, strike cuttings at two seasons, in 

 March and in May, and likewise propagated by layers 

 in August. In the beginning of winter the plants are 

 placed in a cold frame or vinery, and they are brought 

 into a milder temperature as they are wanted. To pro- 

 duce large showy plants, a few of the chrysanthemums 

 of the former year may be selected, and being freed 

 fron suckers, and having the mould shaken from their 

 roots, may be repotted and shifted repeatedly during 

 the summer and autumn.
