THE GREEN-HOUSE.

grow in the autumn, they must be potted and 
grown on in the geranium-house. 
C'oronillas, and other plants, as Salvias, 
Cinerarias, &c., for flowering in the winter, 
should be shifted now, and have all the 
flowers picked off before they expand, — in 
fact, as soon as they appear. 
Heath-House. — All the plants in this 
house, — both Heaths, New Holland, and Cape 
plants, will do as well or better in the cool 
pits than any where else ; and their treatment 
may be summed up thus : — pot all such as 
manifest signs of growth; in fact, all that have 
not been potted before during this season will 
require it now, and many of the free-growing 
ones also, that were potted in spring. In 
watering, take care that the soil never gets 
dry, and if the pots are properly drained, 
plentiful watering will not make it too wet. 
Give them free air, both beneath the platform 
they stand on (see p. 4), and about the tops, 
but shade them in bright sunshine. The same 
treatment must be given if they are kept in 
the house, only the shading is then still more 
urgent. If the plants are removed to the pits, 
the house may be temporarily filled with other 
things. It is only the more delicate kinds 
that require to be now kept in-doors : the larger 
and more hardy of the plants ma)- be placed out- 
doors, in a shady situation, on a good bed of 
coal-ashes, to keep down the worms ; but they 
should be provided with some light covering, 
such as the waterproof canvass, to let down so 
as to shelter them in stormy weather, and 
when the nights are cold. Specimen plants 
must be nursed along with all the care bestowed 
on an infant. 
Camellia-house.— Camellias. — The growth 
of the Camellias will now be getting matured, 
and when this is the case, they will be benefited 
by being removed to a sheltered and protected 
situation out of doors for a month or two, 
after being hardened off in a cooler house than 
that which they made their growth in. The 
very small plants had better not be exposed, 
but should either be kept in the house, or in 
pits. The house may now be kept cooler than 
has been previously recommended, unless, for 
any particular purpose, such as propagation, 
or inducing late growth in any of the plants, 
it may be desirable to keep it to a moderate 
warmth. The warmth will be, of course, re- 
gulated by the amount of ventilation. When 
kept tolerably close and moist, this house is a 
good nursery for sickly plants, or for growing 
young or tender ones, liefer to the general 
management already recommended. When 
the plants are setting their blossom-buds, give 
them clear diluted manure water. 
Azaleas and other plants, kept in this house, 
must be managed in a similar manner. 
PEi.AHGOXiujr-HOUSE. — Pelargoniums. — 
Attention to ventilation, so that there is a free 
interchange of air, without producing cold 
draughts, — shading whenever the sun is clear 
and strong ; watering regularly and liberally, 
— occasionally with clear manure water ; re- 
moving the decaying flowers, and cutting 
down the earlier blooming plants, both for the 
purpose of obtaining a supply of cuttings for 
propagation, and also so that the plants may 
bloom again later in the season, — these are 
the principal routine matters that require to 
be attended to. The plants must have abund- 
ance of air. 
Seedlings. — Where it is intended to raise 
seedlings, proper precautions should be taken 
to ensure seed which is likely to produce some- 
thing worth the trouble of rearing the plants : 
this is done by carefully impregnating the 
pistil of one flower possessing the basis of 
good properties, with the pollen from another 
flower possessing some desirable quality, such 
as colour or marking, absent in the other. 
After impregnation, the flower should be 
loosely tied over with gauze to prevent the 
interference of insects. Not more than one 
flower on a truss, nor, indeed, more than one 
on a plant, should be allowed to produce seed, 
so that all the energies of the plant may be 
directed to that one. Sow the seeds as soon 
as they are ripe, and treat the young plants 
the same as cuttings. If sown early, and 
grown' to some size in the autumn, they will 
flower well in the next spring and summer. 
Old Plants. — Plants which are now going 
out of bloom, or in which the best of the bloom 
is past, should be cut down. These plants, if 
properly managed, will come into flower dur- 
ing the autumn or winter, if required to do 
so, or at any rate will make larger and earlier 
flowering plants for next spring, than such as 
are cut down at a later period of the year. 
They will also furnish a plentiful supply of 
cuttings, which should be put in to form the 
main stock of young plants. After the plants 
are cut down — they should be cut down un- 
sparingly — reduced to mere stumps, if close, 
bushy plants arc valued — keep them compara- 
tively dry, for as there will be no call on the 
resources of the plant by exhalation from the 
leaves, so the roots will be comparatively in- 
active, and, in consequence, an abundant sup- 
ply of water at the root, instead of benefiting 
them, would do them considerable injury. 
They may bo placed in a sheltered situation 
out of doors, which is better for them than 
keeping them confined at all, and they break 
with more vigour, but they ought to be pro- 
tected from heavy rains. As soon as the 
plants have shot out from half an inch to an 
inch in length, the young shoots should be 
thinned a little if at all numerous, as tliey 
usually are ; and eventually, as they get a
