Greenhouse and Stove Plants. 



from the sun, syringing regularly daily, 

 and giving manure-water freely until July, 

 when the plants may be stood out-of-doors, 

 on a bed of ashes to keep out worms ; care 

 should be taken that they do not want for 

 water. In August give larger pots to those 

 that require it, seeing that the drainage of 

 all the stock is right, and towards the end 

 of September take them indoors. Some 

 good growers of Tea Roses never turn their 

 plants out, but keep them wholly under 

 glass. By replacing the old soil with new, 

 and careful attention to keep them free 

 from aphides, red spider, and mildew, this 

 section of Roses may be kept in good con- 

 dition for many years in pots not more 

 than 10 or 11 inches in diameter, the 

 shoots being cut in moderately each year 

 after flowering. 



Grafting is usually done in winter, the 

 stocks previously being raised from cut- 

 tings, which are transferred to little pots, 

 headed down close to the bottom, the grafts 

 put in and then confined in heat until the 

 union has taken place, and some growth 

 been made ; afterwards they are kept on in 

 a warm house until there is enough solar 

 heat to keep them moving, shifting into 

 larger pots as growth advances. Treat 

 subsequently as advised for the plants 

 raised from cuttings. 



The Tea varieties when grown, as they 

 always should be, in a light liouse and 

 near the glass, will bear through the 

 autumn and winter a night temperature of 

 50° or 55° ; the favourite white sort 

 Niphetos should have 5° more than this ; 

 the day temperature ought to be a little 

 higher according to the dull or sunny 

 character of the weather. All Roses under 

 pot culture, or when planted out under 

 glass, should have good rich holding loam 

 to grow in — they do not like light soil 

 — and in potting it should be rammed hard 

 so as to make it solid ; and one-sixth of 

 rotten manure, with a small quantity of 

 sand, should be added if the loam is very 

 heavy. The Tea varieties, which are 

 mainly to be depended on for bloom 

 through the autumn and winter as well 

 as much of the rest of the year, seldom fail 

 to produce flowers from the growth they 

 are continually making when it is not too 

 weak, consequently it is necessary to supply 

 them regularly with the requisite suste- 

 nance to keep up their strength. This can 

 be done by the use of manure- water once 

 a week or so when in active growth ; some 

 of the light artificial manures applied to 

 the surface of the soil in the pots so as to 

 admit of being washed down by the water 

 given, answers admirably for Roses of all 

 kinds, but especially for the Teas. The 



usual course taken with the hybrid per- 

 petuals intended for pot culture, is to 

 strike the cuttings or carry out the graft- 

 ing ojaerations out-of-doors, and when the 

 plants have grown so as to acquire enough 

 strength to take them up and pot them in 

 autumn, after which they should be kept 

 cool out of the reach of frost, and brought 

 on slowly into flower in spring with little 

 fire-heat the first season ; they should be 

 stood out-of-doors where they will be well 

 cared for during the summer when they 

 have bloomed ; a portion of the soil should 

 be removed in the autumn, and larger pots 

 given to those that require them. After 

 thus having a year's growth in the pots 

 so as to enable them to get established 

 they may have more heat. 



The hybrid perpetual varieties should 

 not be forced for bloom in the dead of 

 winter, as the Tea sorts may easily be, as 

 they do not bear forcing so early as the Teas. 

 If forced so as to bloom later the plants 

 will go on improving for years, in the same 

 manner that the Teas will. When planted 

 out in the house they occupy, and grown 

 bush fashion, Roses attain a large size, and 

 yield quantities of flowers, but are not so 

 much under control as to the time of 

 flowering as when kept in pots. It is 

 unnecessary to speak of the way in which 

 Roses may be used when planted out and 

 grown as roof- climbers, or in covering back 

 walls in greenhouses, further than to point 

 to the fine appearance they have when 

 well managed, and when suitable varieties 

 are chosen, although with the assemblage 

 present they cannot be expected to do so 

 well as when they have a house to them- 

 selves. Where Roses are used as climbers 

 in a house where other plants are grown, 

 none but the best growers, with leaves that 

 are the least subject to mildew, should be 

 employed. "Where planted out the soil 

 should be well supplied with manure- water, 

 or surface dressings such as advised for the 

 pot plants.
