BOSES AS CLIMBERS UNDER GLASS. 



■ NDER favourable circumstances Roses can 

 be equally as well grown for a time in the 

 open air as under glass ; but everyone who 

 has grown a Rose out of doors knows with 

 regret how short a time the blooms remain 

 perfect, and in many instances they never 

 reach that state, as a day's strong wind or a 

 few hours' heavy rain frequently destroys 

 the hopes of would-be exhibitors, and many 

 a Rose-grower has taken refuge in the wind 

 and rain as an excuse for not "getting a place" in the 

 prize list. Roses under glass have none of these adver- 

 sities to contend with ; they open without spot or blemish, 

 and nothing whatever need mar their beauty from first 

 to last. 



It is not, however, at the height of the Rose season 

 out of doors, such as the present time, that indoor climb- 

 ing Roses could be placed advantageously against those 

 out of doors. But there is a time when outdoor Roses 

 are no more ornamental than the bare stakes or walls 

 that support them, when climbing Roses under glass 

 appear in all their glory. In February, March, and 

 April every greenhouse or conservatory may be rendered 

 beautiful to look at and delightful in fragrance by a few 

 climbing Roses. Roses are valued at all times according 

 to their abundance and time of blooming, but if there is 

 one time more than another at which they are justly 

 esteemed it is in the early spring months. 



The proper places for Roses under glass are up the 

 rafters, around pillars, and against dead walls, and any 

 other convenient position excepting the entire roof of the 

 house. This affords shade for the plants in summer, but 

 it is unhealthy for them in the spring. I have never seen 

 any Rose shown to greater advantage than when trained 

 right across the rafters in a large house and the branches 

 all bent downwards, with crowds of newly-formed buds, 

 half-opened blooms, and fully-expanded flowers ; no other 

 plant is capable of making a display to equal this in 

 loveliness. Hybrid Perpetual Roses are often U6ed as 

 climbers out of doors. I cannot remember seeing them 

 do well under glass. The Roses best adapted for climbing 

 indoors are the Bourbons, Tea-scented, and the Noisettes. 

 Before speaking of varieties, however, I had better start 

 at the beginning of their culture, and let less important 

 matters follow. 



To grow Roses to perfection as climbers under glass 

 it is not necessary to have a well-heated house ; on the 

 contrary, they thrive excellently in houses where all the 

 heat comes from a brick flue, and this barely sufficient to 

 keep^the temperature above the freezing point when there 

 is 10° or 12° of frost. This is a matter worth remember- 

 ing ; and having settled that they will grow luxuriantly 

 in any temperature between 30° and 50°, the roots must 

 next be provided for. It requires some care to establish 

 climbing Roses, but once this is accomplished they will 

 stand like forest trees; and it is worth observing that 

 after this they seldom or never die-off, and when not

I restricted the stems often grow to an immense thickness 

 and the branches cover a large space. 



No great success will attend growing climbing Roses 



in pots under glass, but they will do well in large boxes 



where they cannot be planted in a border or bed. Much 



the best way of growing them, however, is by planting 



them out; their roots need not be under glass, for, like 



Vines, they do well in outside borders, the stems being 



taken inside through holes in the wall. Each Rose should 



have space at least 3 feet square and deep, filled with. 



good soil to grow in, and if more than this can be given 



so much the better. 'When the ground is not naturally 



porous 6 inches of broken stones must be placed in before 



the soil, which may consist of loam and decayed cow 



dung. When the plants have been in pots previously they 



may be turned into this at any time of the year ; but it 



1 is hardly worth while to remove a large tree from the 



| open air under glass with the hopes of having any desired 



space quickly covered. It is very much the best to begin 



' with small plants with a few shoots about a foot long. 



i It is perfectly surprising the progress these little plants 



make in a short time. A sprig of Marechal Niel that 



was planted three or four months ago had one or two 



! small growths about the length of your finger, and it has 



| now strong thick shoots 7 and 8 feet long. During the 



growing Beason they require abundance of water, also 



liquid manure. This remark applies from the time they 



are planted until the end of their existence. 



As to training, it must entirely be regulated by ths- 

 space there is to cover. In one case it may be desirabls 

 to take up one or two stems a long distance, in another 

 instance a crowd of them may be wanted not far from 

 the root; but this much may be said which applies in 

 all cases — never overcrowd the shoots. 



Mildew sometimes attack Boses under glass : sulphur- 

 ing the leaves is a sure cure for this pest. Green fly 

 is the more troublesome. Small houses may be fumi- 

 gated, but in large houses where there is nothing else 

 wants cleaning it will not pay to do this ; and then a 

 never-failing remedy is to dust the affected parts with 

 tobacco powder and let it remain on the leaves for a day 

 or two. 



I never saw climbing Roses benefited by being pruned 

 hard or too closely in ; it robs them of their gracefulness- 

 and chance of blooming profusely. The shoots may be 

 thinned-out or cut-back whenever they are getting out 

 of bounds. There is another object for which climbing. 

 Roses may be introduced under glass. Many have to 

 grow Boses simply to supply cut flowers ; they do not 

 then need to be trained in a select place in the conserva- 

 tory, but be planted in any out-of-the-way houses where 

 there is room for them. 



Bespecting varieties best adapted for the work, I do not 

 think there ever will be a Bose raised to equal, far less 

 surpass, Marechal Niel. In depreciation of a sameness 

 in an old-fashioned flower garden Pope says — 



" Grove nods to grove ; each alley has its brother ; 

 One half the garden just reflects the other;" 



but I do not think any person would ever have cause to
