seems to be, that the rose stocks are always of much more robust habit, with 
reference to the scions grafted on them, than the stocks of any other grafted 
tree or shrub whatever. 
Watering. All plants in a state of high culture require watering in the 
summer season, otherwise they will not develope their parts to a sufficient 
extent. The rose bush best produces its flowers in the three hottest months, 
June, July, and August; and neither in Britain, nor on the Continent, will 
roses expand their blossoms fully, or have strength to resist the attacks of 
insects, unless they are liberally supplied with water. Before they come into 
flower, the leaves should be syringed every evening in dry weather, and the 
root abundantly supplied either with common water, or liquid manure. Dwarf 
roses require less water than standards ; because the nearness of the bush to 
the ground, by covering the soil, prevents evaporation. Lime water (that is, 
lime held in solution in water, and not such a mixture of lime and water as 
will leave a coating of lime on the plants) may be used, both with the syringe 
and at the root; and, though it will not entirely destroy the aphides, those 
great enemies of roses, yet it will check their increase, and it will totally 
destroy caterpillars of every kind. To destroy the aphides, after syringing 
with pure water or lime water, the plants should be sprinkled with the 
powdered leaves of tobacco, or refuse snuff, as directed under the head of 
Insects, and the syringing left off for a few days; after which they should be 
well washed with clean water. 
Growing in Pots and Forcing. The dwarf-growing roses, and, indeed, most 
sorts as dwarfs, may be grown in pots; care being taken to turn them out of 
the pots once a year, and, after trimming their roots and shoots, to repot 
them in fresh soil. So complete is the command of the cultivator over a 
rose in a pot, that, with the aid of glass, a choice of sorts, and the power of 
applying a very little heat in the winter months, he may have roses in abun- 
dance all the year. Cabbage and moss roses, when they are to be forced, 
should be taken up out of the free ground as soon as they have done flowering,
