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 ont, 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 house 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 operations 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. :
