be separated from the rest of the pleasure ground by being formed in a sunk panel, with sloping bank of turf all around. But when carried out on a large scale a close hedge is requisite; for this hornbeam or beech will be suitable. Clipped yew will have the grandest effect, and bring out the colours of the roses to perfection. The frontispiece is a design for a rosarium. If I had to carry such a design into effect I should construct four large covered entrance ways, over which would be trained luxuriant growing climbing roses. The boundary would be of common or Irish yew, the latter preferable, but most expensive. Within this boundary a broad gravel walk all round. This should be ten feet wide, and on a dead level. Within this walk a ten feet circle of grass turf with standard roses of uniform height all round. To get to any of the short cross walks in order to proceed towards the centre, we should prefer to walk across the turf rather than break its continuity with any intersections of gravel; therefore proceeding across this grassy ring we come next to a circular walk arched over throughout with climbing roses, or bounded on both sides with roses trained to chains. This walk should be ten feet wide if arched over, but if open and bounded on each side with roses on trains, it might be, like all the open walks within, five feet wide. Within this we should have a series of eight beds ten feet wide, intersected with cross walks, arched over with climbing roses. These beds would be appropriated to China roses, which would be gay with bloom from May to December. After this, still proceeding towards the centre, we have a succession of walks and beds, each five feet wide, all the cross walks arched over, and the arches covered with climbers. All these beds to be planted with named roses in groups, and the whole grown as dwarfs. The centre to consist of a mound of about ninety feet diameter, with walks entered by archways, which would divide the mound into compartments, and give access to the temple on the summit. All these compartments to be appropriated to China roses, each compartment consisting of one kind only. The temple would afford sites for a few pillar roses, and a position from which the whole plantation could be viewed to advantage. If carried out according to these measurements this rosarium will occupy a space of ground 260 feet in diameter, or nearly one-third of a statute acre. CULTURE OF ROSES IN THE OPEN GROUND. HE rose is as luxuriant in its habits as in its beauty. It will not be starved, and it will disdain shabby treatment of every kind. It thrives in greatest perfection on a deep, strong, well-drained loam, and that must be liberally enriched with thoroughly-decayed manure. As the rose is somewhat of a gross feeder, any of the stronger manures may be advantageously employed in its cultivation: pigs' dung, night soil, superphosphate of lime, and stable dung; freshmanure should never come in contact with the roots. The dung must be well rotted and perfectly sweet, and it must be thoroughly incorporated with the soil before the roses are planted. But it does not follow that even if the soil of the garden is a deep strong loam, that therefore roses are sure to succeed on it. Leaving out the questions of aspect and climate, it is more a matter of actual experience than calculation as to whether roses will flourish in any particular spot, however well the soil may appear fitted for them. The roses must be tried on the soil, and until actual experience has proved its fitness for them, choice |
