258 PROPAGATION OF PLANTS. 



buds are forming-. The boxes may then be placed in a position where 

 the cuttings will get a little bottom heat, which will force out the buds 

 and sprouts. When the young plants are of sufficient size to handle 

 readily, they may be potted oil, using two or three inch pets. The time 

 to make root-cuttings is after the plants have ceased flowering, or when 

 they are in a semi-dormant state, as they usually are during the latter 

 part of winter. Cuttings of the young terminal and side shoots, when 

 about two inches long, are in the best condition for striking, and if 

 placed in pure sand in close frames, or under bell glasses, the larger 

 proportion can be made to grow, but the plants are so easily propagated 

 by root-cuttings that our florists depend mainly upon this mode for in- 

 creasing their stock of Bouvardias. 



Broussonetia (Paper Mulberry). Only one species, of which there 

 are several varieties in cultivation. All low-growing trees from China. 

 Propagated by seed, cuttings of the mature wood taken off in the Ml 

 and stored during winter .in a moderately warm place. Also increased 

 by layers, suckers and cuttings of the rools. 



Suxus (Box Tree). A genus of well-known, hardy evergreen trees 

 and shrubs. There are many varieties in cultivation, all of which thrive 

 best in a light, well-drained soil. Propagated by seed, cuttings and 

 layers. Green cuttings, taken from the plants in summer and placed in 

 frames and shaded duiing the he.it of the day, produce roots quite freely, 

 and in a few days. Ripe wood cuttings, taken off in the fall and placed 

 in boxes in a cool greenhouse, will usually become well rooted by the 

 following spring. Some of the varieties grow quite readily by cuttings 

 planted in the open ground in spring, but the soil should be packed 

 firmly about the ba:e of the cuttings to insure the production of roots. 



Callicarpa (French Mulberry). Handsome little shrubs, cultivated 

 for their ornamental berries. A genus of only five species one Ameri- 

 can, one from Japan, two from India, and one from China. Propagated 

 by seed, divisions, or cuttings o2 the young shoots in spring, placed 

 under a bell glass in a grcenhou&3 or in close frames where they will 

 receive a littla bottom heat. 



Callistemon, Handsome greenhouse shrubs, most of the species 

 being native of New South Wales. Propagated by seed when it can be 

 obtained, but the best flowering plants are raised from the ripe wood 

 the cuttings placed in pure sand in frames or under a bell glass. 



Callttris. A small genus of tender, evergreen trees, closely allied 

 to the Arbor-vitses, but with very long, slender, joint d branches. Propa- 

 gated by seed, and cuttings of the branches taken off in the autumn and 

 kept in a cool greenhouse through winter, or stored in a frame where 

 they will not freeze. 



Calluna (Heather, Ling). A genus of the Heath family, indigenous 

 to Europe and to rather limited areas in North America. Propagated 

 by cuttings of the green, tender shoots planted in pure sand under glass. 

 To secure the best cuttings, the plants should be grown in the house
