THE GREEN-HOUSE.

liberal supply of water and liquid manure 
occasionally. About tbe middle of September 
they should be taken up and potted in sis, 
seven, or eight-inch pots, according to circum- 
stances, in a compost similar to the above; 
afterwards place them in the frame, keep them 
close for a few days, and wet the foliage three 
or four times a-day, to keep them from flag- 
ging : in about u fortnight they may safely be 
removed to the green-house, and watered more 
sparingly ; they will bring a good succession 
of bloom throughout the autumn. The double- 
flowered ones must be raised from cuttings, 
and flower during the whole winter. 
Lobelias. — Some plants of the Lobelia, such 
as L. fulgens and L. speeiosa, make splendid ob- 
jects when wellgrown; theyrequire to be parted 
now, and each division, or single heart of the 
old plant, potted singly into a small pot, and 
then plunged in a hot-bed ; the kind of soil 
is not material till they get larger. As the 
young plants begin to grow in the warm 
frame, they must be removed to a colder situ- 
ation, and gradually hardened to stand in a 
green-house ; and they must also be re-potted 
when they require it. For some months yet, 
they may be kept with advantage in the pits 
and frames. 
Chimney Campanula. — This plant (Cam- 
panula pyramidalis) may readily be multiplied 
to any extent by planting portions of the roots, 
an inch or so long, in pots, and placing them 
in heat: the old plants require shifting occa- 
sionally. 
Siphoeampylos bicolor. — Among winter- 
flowering green-house plants there is nothing 
more gay, and certainly useful, than this 
Siphocampylos, which is not half so commonly 
grown with this view as it ought to be : it 
forms upright shoots, four or five feet long, 
with leaves like those of a peach-tree, from 
the axils of each of which, throughout nearly 
its whole length, one of its pretty yellow and 
red tubular lobelia-like flowers are produced, 
and remain a long while in perfection. It 
should now be started to grow, and encou- 
raged to make strong shoots during summer. 
Watering. — A general caution may be 
given as to watering plants in pots. Be cer- 
tain when you do water, that it is effectual, 
and that the whole mass of soil is moistened : 
the surface often appears moist, when below 
it is quite like dust ; and nothing can be worse 
for the plants. 
1 1 i.atii-IIouse. — Ericas,$'c. — The potting 
of the plants may now be more fully proceeded 
with: let it not, however, be a general indiscri- 
minate shifting of the whole collection, but 
only those which are in a condition to require 
it, by having their pots moderately filled with 
roots ; the potting of others which are less 
advanced in this respect must be deferred 
until a later period in the season. In potting 
heaths — or indeed specimen plants of all kinds 
which are regarded as being of value — use 
only such soil as is rough, open, and fibrous, 
and always use it in a rough state, in lumps 
of greater or less size, according to the size 
of the pots which are employed. Among the 
soil at the time of potting introduce a quan- 
tity of rather large lumps of charcoal, besides 
having the bottoms of the pots well drained 
with rubble, broken crocks, or whatever mate- 
rial of a porous nature may happen to be at hand 
for use. For some time after they have been 
potted, all plants require proportionately less 
water ; and this rule continues in force until 
the new soil becomes intersected with the 
young roots. Large plants seldom require 
shifting more than once in the year, and this 
should be done during the summer, just at the 
time when each particular kind is just about 
to renew its growth. 
Watering. — Except in the cases just alluded 
to, of newly-potted plants, in which watering 
must be done very cautiously indeed until the 
roots get into the new soil, the plants will 
require at this season to be more liberally 
watered. Large plants of heaths, as well as 
other plants growing in the same kind of 
soil, are very liable to get much drier in the 
interior of the mass of earth, than the exterior 
surface would lead one to expect. To this 
state of things the loss of many fine specimens 
must be referred. It is therefore of the 
utmost importance to be sure that, in the case 
of every plant, this is not the case, but that 
the soil is thoroughly and evenly moistened 
throughout. When soil of the kind used for 
these plants is once allowed to become dried 
in the interior, it is very difficult to get it 
again thoroughly moistened, the water applied 
being apt to pass off by the sides of the pot, 
instead of penetrating throughout the mass. 
Temperature, <yc. — From 40 degs. as a 
maximum night temperature, to 45 or 50 digs. 
in the daytime, will be sufficient. Air should 
be given both night and day, but not so as to 
cause drying or chilling draughts. 
Pruning. — To keep the plants bushy, so as 
to form them into neat and handsome speci- 
mens, the stopping of the strong shoots must 
not be neglected ; nor should it be delayed 
until they have grown to too great a length, 
for they would thus expend much of the 
energy of the plant in a useless manner, that 
might have been turned to a more profitable 
account. 
Azaleas. — The greater part of these will 
now be advancing to a forward slate as 
regards blooming, and it is of very great im- 
|iuri;inee to keep them regularly watered, for, 
if they are allowed in gef dry, the blossom 
buds will many of tin in fill off. The plants
