words : Prune after flowering. Of course, dead and diseased 

 wood may be removed at any time. But the cutting of twigs 

 and branches during winter is probably wrong in ninety-nine 

 cases out of a hundred, because no account is taken of the method 

 which the plant follows in producing its blossom buds. Flower- 

 ing shrubs are of two classes : those which develop their blossom- 

 buds during one summer and autumn for bloom in the following 

 spring — ^by far the largest class since it includes all shrubs that 

 flower before midsummer ; the other, those few that make their 

 flowers late in summer on the growths of the same season's de- 

 velopment. To the first belong the lilac, golden bell, Judas-tree 

 or red bud, etc. ; to the second, hydrangea and other bushes that 

 bloom in late summer. A group that may be considered as 

 between these two includes weigela, some of the spiraeas (the late 

 bloomers), common quinces, and other shrubs which bear their 

 flowers on short shoots developed from buds that have been 

 formed the previous summer. They differ from the first group 

 in that the over-wintering buds contain nascent stems and leaves 

 as well as flowers, instead of flowers only. From the second 

 group they differ in that these buds are developed the previous, 

 instead of the same, season.
