PEOPAGATioN OF THE ROSE. 49 



or Boursault, or the Dog Rose, in good-sized pots, and well estab- 

 lished; for they may be budded later, protected better, and indeed 

 some of the seedlings which partake much of the China are tender, 

 and really require protection from the frost. 



Retarding the FloTreiing of tlie Rosa. 



The most simple method of retarding the flowering of the Provence 

 and Moss Eoses, so as to have the plants in bloom late in autumii, is 

 to cut off the tops of the shoots produced in the spring, just before 

 they begin to show their flower buds ; the effect of this treatment will 

 be to cause the plants to throw out fresh shoots, which will bloom 

 later, according to the period in which the operation is performed. 



It may also be done by transplanting the bushes early in the spring, 

 as soon as they have formed their buds, which should be cut off. The 

 roots must not be allowed to dry before they are put into the earth 

 again; and they will require artificial watering if the season should be 

 dry, to make them flower late in the fall 



Propagation by Cuttings. 



When the earliest shoots of the China Rose are about four inches 

 long, cut them off close to the old wood, plant them in pots half filled 

 with soil, and plunge them in a warm situation, placing over the pot 

 a flat piece of glass, to exclude the cold air ; the glass should be wiped 

 occasionally. Thus treated, they wiU make blooming plants by autumn. 



Indian Roses, and oUmbing kinds, are also easily propagated by 

 cuttings and slips, protecting them as above, or by a hand glass, when 

 the climate is cold. 



Propagation by Suckers, 



Many roses, indeed most of them, growing on their own roots, 

 instead of by grafting on a stock, constantly spread at the roots, and. 

 branches force their way up, much to the annoyance, sometimes, of 

 the men in charge of the rosary. In the spring months, their suckers 

 should be looked for, and when found, they should be taken off at 

 once, far enough under ground to get a piece of root with them. 

 These should be replanted instantly on the removal; but if a piece be
