96 THE CANADIAN HOETICULTURIST. 



found tliat in dry and hot seasons the layers do not root freely, and 

 that it is often necessary to allow the layers to remain for two years 

 before separating tli^m from the parent plant. 



The Flowering Hawthorns are best and easiest propagated by 

 budding them upon the common White Hawthorn. The buds take 

 readily, unite firmly, and grow rapidly. We have not tried the experi- 

 ment of budding or grafting these upon our common Wild Thorn; if 

 any of our readers have made trial of this method of propagating them, 

 it would be very interesting to know the result. 



Deutzia Gracilis, a small, slender, graceful shrub, producing pure 

 white, bell-shaped flowers in great profusion, is best propagated also by 

 placing a plant in the greenhouse, and setting green wood cuttings in 

 bottom heat, under a bell-glass ; though it is quite possible to succeed 

 when the bell-glass is not used. 



Deutzia Crenata flore jjileno, comes into bloom towards the end of 

 June. It is the most showy of all the Deutzias, bearing its hanging 

 bell-shaped, scolloped blossoms on the shoots of the current season's 

 growth, throughout the entire length of the shoot. The flowers are 

 very double, pure wdiite, splashed with bright rosy pink on the outside, 

 and literally cover the branches so as nearly to conceal the foliage. This 

 we have cultivated only from green wood cuttings taken from the parent 

 plant in summer and set in a gentle bottom heat. We beheve how- 

 ever that it might be gTown from hard wood cuttings taken off in the 

 fall and kept in moist sand until March, and then set in the propagating 

 bed of a greenhouse with a gentle bottom heat, and also that it might 

 be possible to grow it from layers in the open ground. 



The Syringa, or Mock Orange, is very readily grown from layers ; 

 from suckers that spring up around the parent plant ; and by dividing 

 the parent plant itself when it has attained to suflicient size. 



Weigela Rosea, a free flowering shrub, with showy, tubular flowers, 

 of a light rose color, blooming in June, is very easily proj)agated from 

 cuttings, in a gentle bottom heat, or even under a sash without bottom 

 heat, in sand ; also by layering. 



Perhaps these instances will be sufficient to give our readers an 

 idea of the various methods of propagating shrubs. As a rule most of 

 them can be made to grow from layers, keeping them layered two years 

 if necessary; when this method fails, resort must be had to green wood 

 cuttinfjs and bottom heat
