THE GREEN-HOUSE. 
ing up a display of flowers. The different 
Indian balsams are exceedingly well suited for 
this purpose, and may be grown into splendid 
specimens. Their treatment may be found 
detailed at p. 493 of the Annals of Horticul- 
ture. 
Chrysanthemums. — Much of the autumnal 
display of a conservatory depends on a supply 
of these plants ; and, indeed, through the 
earlier part of the winter they maintain their 
ground, if managed with that view. Not that 
these are the only flowers which can be had at 
that time of the year, for by the aid of forcing, 
almost any kind of plant may, if required, be 
brought to bloom in winter ; but Chrysan- 
themums are peculiarly autumnal flowers, and 
though they want an agreeable fragrance, they 
are very showy ; besides, they have a degree 
of freshness and distinctness from the summer 
flowers, with which at that season one has 
been most familiar, which is an additional 
recommendation. The potting of the plants 
should be attended to, and, above all, the 
watering of them, so that they may retain 
their foliage in a healthy state. If they have 
been planted out, with a view to taking them 
up for potting towards the autumn, it will be 
advisable occasionally to thrust a spade down 
all round them, at a little distance from the 
stem, beginning, perhaps, at six inches, and 
increasing the distance very slightly each time. 
This will moderate their growth, as it will act 
as a gradual and not sudden check, and will 
cause them to grow dwarfer and more bushy. 
For the same purpose, the strongest shoots 
should be occasionally topped. 
THE GREEN-HOUSE. 
Green-house plants will now, for ths most 
part, be removed for their ordinary habita- 
tions, which will afford accommodation for the 
growth of tender annuals, such as the various 
Impatiens, Globe amaranths, Cockscombs, 
Egg-plants, Browallias, &c. ; and also for 
many stove plants, which may be removed 
here for the summer with great convenience. 
When the green-houses are thus employed, 
their management as regards temperature,mois- 
ture, and ventilation, must be assimilated with 
that of the plant stove, for which see p. 253. 
The tenderer of the green -house plants will 
be removed into -cool pits, well ventilated, 
which offer the best of all situations for 
growing them in the summer. The more 
hardy and robust kinds should be placed in any 
convenient and appropriate situation out of 
doors, till the middle of September, or later, 
if the autumn proves fine. 
House fob Miscellaneous Plants. — 
This structure may in a great measure be 
devoted to the purpose just named, that is, 
the growth of tender annuals and stove 
plants, such as Achimenes, Gloxinias, and also 
many of the hardier of the stove shrubs, while 
they are making their growth. When used 
for this purpose, the house should, as above 
remarked, be subjected to the general ma- 
nagement of the stove, but may be kept some- 
what — that is a few degrees — cooler. If the 
house is not devoted to this purpose, it may 
very properly be used in preparing plants fol- 
iate blooming in the conservatory ; these, how- 
ever, may be quite as successfully grown and 
prepared in pits ; and such consist of Salvias, 
Heliotropes, Pelargoniums, shrubby Calceo- 
larias, Coronillas, Siphocampylosbicolor, China, 
Hybrid China, and Tea-scented roses, &c. &c. 
These plants, whether grown in the house or in 
pits, require as free ventilation as can be given, 
and to have the atmosphere about them kept 
moderately damp, by giving the walls, paths, 
pots, &c, frequent gentle sprinklings with the 
syringe. 
Primulas. — These plants are scarcely 
equalled for usefulness and for gaiety during 
the winter months, especially the double va- 
rieties, white and purple. Seeds of the 
ordinary varieties, both plain and fringed, 
may be sown now, for a stock of plants to 
bloom next winter. The double ones, which 
do not produce seeds, should now also be pro- 
pagated by division ; cuttings of them may 
also be planted. In dividing them, take the 
old plants, and separate them into as many 
pieces as there are single hearts, or shoots, and 
get as many of the old roots attached to each 
division as possible : those pieces to which no 
roots can be obtained, must be planted as cut- 
tings, and will root readily enough if kept 
close for a time. Pot the others in light soil, 
composed of equalpartsof sandy loam and peat, 
and place them in a hot-bed, where they will 
get agentle bottom heat. When they are rooted 
freely, shift them into large pots, and place 
them in an ordinary green-house, not ex- 
posing them too suddenly : pick off all the 
blooms that appear. In October, shift them 
into their blooming-pots, which may be six or 
eight inches in diameter, according to the size 
of the plant, and the convenience for growing 
it; they must not have too large pots for the 
quantity of roots they possess, and must be 
well drained. They will begin to bloom in 
November, and will continue for several 
months in succession. After blooming, rest 
them till the following July. 
TropiBolums. — When these have done 
flowering, and begin to show symptoms of 
decay in their foliage, dry them off gradually 
by withholding water. Keep the roots in a 
dry place, — beneath the plant-stage in the 
green-house is a good place, if it be dry, and 
not subject to drip. Keep them at rest, till 
the spring, if you can ; but if they begin to
