GREENHOUSE AND CONSERVATORY.
Frequent attention is now necessary in the giving and taking away of
air as the alternations of bright sunshine and clouds occur, and also to
temper cold winds by the admission of air on the south side. If
severe weather has
been now experienced, and extra fire heat used in
consequence, many plants that may appear all right may, nevertheless, be
very dry, and if they are not examined, and when very dry, well soaked
with water, they will soon show unmistakeable signs of approaching
Azaleas (Indian).--Young plants that have commenced their growth to be
repotted. Shift Achimenes, Begonias, Gesneras, &c., and keep them in a
warm, moist situation.
Bulbs.--Pot Cape and other bulbs in a compost of loam, leaf mould,
with a good sprinkling of sand, as soon as they begin to make growth in
Heaths.--Continue to shift as they may require, using sandy heath-soil
full of fibres, with an abundance of drainage. Be sure that the ball
is thoroughly moist before shifting; for if perfectly dry when that
operation is performed the waterings afterwards given will pass freely
through the fresh soil without penetrating the old ball. Give them all
the air possible, avoiding north or north-east winds.
Potting must be in progress, and include a good proportion of the
occupants of these houses.
STOVE AND ORCHID-HOUSE.
Push Allamandas, Clerodendrons, Stephanotises, &c., forward as briskly
as possible; but be in no hurry to train them, as freedom in growth is
advantageous to a certain extent. Use all means to check the increase of
Orchids.--The general collection to be favoured with a good steaming
every clear morning for about half an hour: this to be done by
sprinkling the flues or pipes when warm. Plants in a growing state to
be slightly shaded, to prevent flagging from too copious a perspiration
during a sudden mid-day bright sunshine. Orchids are generally increased
by passing a sharp knife between the pseudo-bulbs (taking care to leave
at least two or three undisturbed next the growing shoots) so as to
sever one or more of the dormant bulbs from the parent plant, which
should remain until it shows signs of growth, when it may be taken off
Cherries.--The syringe to be used freely except when in bloom, plenty of
air to be given, and the green fly kept down; shutting up with a little
extra solar heat in the afternoons of bright days.
Figs.--Abundance of syringing and good waterings with liquid manure
may now be given them. Sudden changes in their treatment will cause
the fruit to drop, all the shoots when six or eight inches long to be
stopped to encourage the formation of a second crop.
Melons.--Use strongish maiden loam by itself to grow them. See to the
linings, attend well to setting, and maintain an airy and dry atmosphere
when in blossom. Keep the shoots at all times thin.
Peaches.--Frequent attention to be given in arranging the young shoots,
disbudding and thinning. A knowledge of the state of the border is
necessary, whether retentive or porous, that no serious errors may be
made by withholding a sufficient supply of water, or by giving too much.
The temperature of the early house to be from 55 deg. to 60 deg. by
night, ranging from 75 deg. to 80 deg. by sun heat, and allowing 65 deg.
by artificial heat, on dull days.
Pines.--A day temperature of 75 deg. to 80 deg. to be maintained during
the progress of the fruit to maturity, accompanied by atmospheric
moisture. Succession plants to be supplied with a steady moist heat, and
to be carefully sustained after potting, to induce a healthy action of
the roots. Shading is sometimes necessary during bright sunshine.
Vines.--As the lower parts of the stems are generally close to the
heating apparatus, it is advisable to bind them up with moss or
haybands, neatly clipped, as far as the parching heat extends. The moss
or haybands being damped morning and evening with the syringe, will keep
the bark and stems in a healthy state, and will frequently induce a mass
of roots to be produced there. That by watering occasionally with liquid
manure will contribute to sustain the vigour of the trees.
