semi-cactus types (or loose-flowered forms), and the im- 

 provement of the singles, it again has taken a front rank 

 among late summer flowers, coming in just in advance of 

 the Chrysanthemum. 



The single varieties may be grown from seed, but the 

 double sorts should be grown from cuttings of young 

 stems or from division of the roots. If cuttings are 

 to be made, it will be necessary to start the roots early 

 either in a hotbed or house. When the growth has 

 reached 4 or 5 inches, they may be cut from the plant 

 and rooted in sand. Care should be taken to cut just 

 below the joint, as a cutting made between two joints 

 will not form tubers. The most rapid method of pro- 

 lhlia pagation of named varieties is to grow from cuttings 

 in this way. In growing the plants from roots, the best 

 plan is to place the whole root in gentle heat, covering 

 slightly. When the young growth has started, the roots 

 may be taken up, divided, and planted out 3 to 4 feet apart. 

 This plan will ensure a plant from each piece of root, 

 whereas if the roots are divided while dormant, there is 

 danger of not having a bud at the end of each 

 piece, in which case no growth will start. 



The Dahlia flourishes -best in a deep, rich, 

 moist soil, although very good results can be had 

 on sandy soil, provided plant-food and moisture 

 are furnished. Clay should be avoided. If the 

 plants are to be grown without stakes, the center 

 of each plant should be pinched out after making 

 two or three joints. By doing this the lateral Dahha 

 branches will start near the ground and be stiff enough to 

 withstand the winds. In most home gardens the plants are 

 allowed to reach their full height, and are tied to stakes if 

 necessary. Dahlias are very susceptible to frost. The tall 

 kinds reach a height of 5-8 feet. 



After the first frost, lift the roots, let them dry in the 

 sun, shake off the dirt, trim off tops and broken parts, and
