OSMANTHUS 



OSMARONIA 



flowers. It is of the easiest culture in an intermediate 

 temperature. It is almost a continuous bloomer, 

 although ordinarily it should be rested in late winter or 

 summer in order to ripen the wood for fall and winter 

 bloom. Be careful not to overpot, and keep the plant 

 free from mealy-bug. Out-of-doors all the species prefer 

 a place shaded from the mid-day sun. Propagation is 

 usually by cuttings of half-ripened wood in late summer 

 under glass; seeds are rarely obtainable and do not 

 germinate until the second year; grafting on privet, 

 as is sometimes done, is not to be recommended. 



Greenhouse treatment of the Olea fragrans of gardens. 

 This fragrant plant can be grown in a cool house, one 

 that has a night temperature of 45 to 50 in the 

 winter months. The plants should be grown just as 

 cool as possible in the summer months, and allowed 

 to come into flower in their natural way, as they do not 

 take kindly to any kind of forcing. About the first of 

 June, they may be plunged outside in a partially shaded

situation where they can be watered and syringed. By 

 September, they may be placed in a cool and airy house 

 where, by receiving care as to watering and ventila- 

 tion, they will show bloom late in autumn or early 

 winter. When they are through flowering, they may be 

 repotted, using a compost of fibrous soil four parts, 

 well-decayed cow manure one part, leaf-mold one part, 

 and enough of sand to keep it porous. They will root 

 from ripened points of the young growth placed in 

 sand in a warm prppagating-bed. When rooted, they 

 may be potted off into small pots, and grown on in a 

 temperature of 50 to 55, giving them shade and moist- 

 ure until they become well established. Give repeated 

 shifts as they fill the pots until they have reached a 

 7- or 8-inch pot. They may be kept for some time in 

 good vigor by top-dressings and with liquid manure in 

 these pots. When using the compost for these large 

 pots, let the mixture be as lumpy as possible. Do not 

 overlook the importance of giving them plenty of 

 drainage as they will not tolerate anything like a 

 stagnant compost. If the aphis bothers, give light 

 fumigations for two or three nights. When scale shows 

 itself, give a thorough sponging with some good insecti- 

 cide. (J. J. M. Farrell.)
