CYTISUS 



After repotting thev are kept close and often syringed 

 until they are establisiied ; tiien they ought to have plenty 

 of air and only slight shade. When the new growth has 

 been finished "they may be put in the open air until frost 

 is threatening. During the winter they should be kept 

 in a cool greenhouse with plenty of light and carefully 

 and moderately watered. From January they may be 

 transferred gradually in a warmer house for forcing.

Cuttings started in early spring, transplanted several 

 times and then gradually hardened off, can be grown into 

 flowering specimens for the following spring. Prop, by 

 seeds sown in spring and by greenwood cuttings under 

 glass ; they are also sometimes increased by layers or by 

 grafting. As stock C. nigricans is much used, or La- 

 burnum vulgare for small standard trees ; for plants 

 grown in the greenhouse or south, C. C'anariensis is a 

 good stock. Alfred Rehdee. 



Of Cytisus, the young growths root readily in Decem- 

 ber and January in the ordinary way. They should be 

 shifted on as they grow. Hood sized plants can be pro- 

 duced if shifting and pinching is not neglected. By the 

 following winter, the winter-propagated plants should 

 be in 5-in. pots, in which size they are most useful. 

 Keep very cool during winter and withhold any forcing. 

 They flower in March, or, if kept at a night temperature 

 of 45°, as late as April. Syringe at all times to prevent 

 red spider. To produce good sized plants in one year, 

 it is best to keep them plunged on a bench under the 

 glass the entire summer, with little shade. Older plants 

 can be plunged out of doors during July, August and 

 September. William Scott.
