spring. Great care must be given to shading and watering. 

 Hydrangea paniculata var. grandiflora and Akebia quinata are 

 examples; or any deutzia or more 

 easily handled plant of which stock 

 is scarce may be cited. 



Part of the leaves is removed, as 

 a rule, before these firmwood cuttings 

 are set, as shown in the rose cutting, 

 Fig. 123, and the hydrangea cutting, 

 Fig. 122, and the viburnum, Fig. 124. 

 This last picture (Fig. 124) was made 

 in a western New York nursery Sep- 

 tember 17. It was then ready to be 

 potted or set in a bed. Clipping the 

 leaves is not essential, but it lessens 

 evaporation and the tendency to 

 "flag" or wilt. In most species the 

 top can be cut off the cutting, as seen 

 in Figs. 99 and 122, but in other 

 cases it seriously injures the cutting. 

 Weigelas are likely to suffer from 

 such beheading; an unusually large 

 callus forms at the bottom, but

 occurs in what some nurserymen 

 call "end growers," among which 

 may be mentioned weigelas (prop- 

 erly diervillas), the shrubby altheas, 

 Cercis japonica, and such spireas as 

 S. trilobata, S. rotundifolia var. alba 

 of gardens, and S. cantonensis (S. 



Reevesii of the trade), and the var. robusta (probably properly 



S. blanda).
