THE GREEN-HOUSE. 
placed in them. If the house is filled with 
tender annuals and stove plants, a moist and 
comparatively close atmosphere must be kept 
up, by frequently syringing at morning and 
evening, giving smaller quantities of air 
through the day, and shutting up close early 
in the afternoon, syringing at the same time. 
If, on the other hand, any of the green-house 
plants are placed here for shelter, or the house 
is filled with young stock of any kinds of 
green-house or half hard)' plants, which is 
sometimes the case when pit room is scarce, 
then full ventilation must be permitted, both 
day and night : when employed for rearing 
young stock, it is more necessary to have 
recourse to, and continue the practice of, shad- 
ing, than for more mature plants of any kind; 
but if the days are very hot and bright, most 
kinds of green-house plants are the better 
for a slight shading in the hottest part of 
the day. 
Primulas. — Sow a few during this month, 
to provide a succession of plants, and treat 
them in. every respect as recommended at 
p. 290. When there are any old plants saved 
from last season, let them be potted now, and 
placed in a frame, or in the green-house at 
once : though blooming less finely than young 
plants, they generally come into bloom earlier, 
unless a few had been sown very early. 
Annuals. — Some few of the annuals which 
are worth growing to bloom during the winter, 
should be sown now in pots or boxes, and may 
be kept in the frames till the end of next 
month, when they should be removed to the 
shelves near the glass in the green-house. 
Two or three kinds of Schizanthus, in- 
termediate Stock, Mignonette, Brachycome, 
Erysimum, and Nemophila, may form part of 
this sowing; the selection should by no means 
be extended promiscuously, or even very 
much extended at all. 
Coronillas, and such other half-shrubby 
plants as have been provided for winter flow- 
ering, including Salvias, Heliotropes, Gera- 
niums, Shrubby Calceolarias, Cinerarias, &c, 
should still have all the flower-buds that may 
be produced removed, in order to throw all 
their energy into the plant, to enable it to 
flower more vigorously and profusely later in 
the season, when actually required. The 
earliest ones need not again be repotted, if it 
was done late in the last month, and they 
received a liberal shift ; if otherwise, and also 
in the case of later plants for succession, the 
proper shifting of each batch, and forwarding 
them a stage, must not be neglected. 
Kalosanthes. — Two sets of plants of this 
fine thing should always be grown, so that, 
individually, the plants may form strong shoots 
and get them well matured one year, and pro- 
duce flowers the following one. Those that 
have been making growth should receive a 
change of treatment to induce them to mature 
and ripen that growth previous to the approach 
of winter. Those that have been flowering 
should be cut back and set in a cool place, 
with scarcely any water till they recommence 
growing, when they may be put into smaller 
pots, in rather sandy soil of a loamy basis. 
Some of the shoots may be planted as cuttings 
and will require no water, or scarcely any, 
until they are rooted. 
Chrysanthemums. — These plants will now 
be advancing considerably, and will require 
good attention. Let them be occasionally re- 
potted, according to the size of the pots to 
which they may be limited, and the size the 
plants are required to be of, when arrived at 
a blooming state. Keep them regularly and 
thoroughly watered, sometimes using manure 
water, or their foliage will exhibit manifest 
evidence of neglect, by that at the lower part 
of the stem turning yellow, or falling off. Stop 
the very strong shoots for bushy plants, but it 
must not be continued any later. Small plants, 
a few inches high, though they produce much 
smaller blooms than the stronger plants, are, 
nevertheless, very pretty ; there are two ways 
of obtaining them — either lay the points of 
the blooming shoots, during the latter part of 
the month, into small pots, and remove them 
when rooted, giving them one shift ; or take 
off the tops, as cuttings, earlier in the month, 
and root them in a close but very mild hotbed. 
In either case, the plants, when sufficiently 
rooted, are treated like established plants. 
Ipomteas. — Any of the species which do in 
a green-house, if sown now, and kept in small 
pots on a dry shelf in the green-house, during 
the winter, will bloom much more certainly 
next season than if sown in spring. The same, 
as a principle, applies to many other plants, 
too numerous to mention here. 
Thuribergias. — A good stock of these plants 
— of each variety, especially alata alba and 
aurantiaca — should be sown now, in a rich 
light loam, and potted into small pots, and 
stored by on a dry shelf at a warm end of a 
green-house. They will become established 
plants by the spring, and will bloom early. 
Jthodanthe Manr/lesii. — Though growing 
out of doors in favourable situations, in sum- 
mer, this beautiful little annual plant can only 
be properly regarded as a green-house plant,for 
there only, in our changeable climate, can we 
ensure full development. The seeds should be 
sown now, and the plants kept all winter, in 
small pots, on dry airy shelves in the green- 
house. A sandy, somewhat peaty,soil suits them. 
Bulbs. — The Dutch bulbs, such as Hya- 
cinths, Narcissus, Jonquils, Tulips, &c. cannot 
be dispensed with, where flowers in winter are 
any object. The great fault as respects these
