GREENHOUSE AND CONSERVATORY.
Now that the dull, foggy days and sharp frosty nights have arrived, it
is necessary to keep all plants that have finished their growth free
from excitement, and rather dry at their roots. A gentle fire to
be applied during the
day, which will allow the advantage of a free
circulation of fresh air, and, by closing up early in the afternoon,
will retain sufficient heat to resist the encroachments of ordinary
frosts during the night. But if the frost should set in severely, night
coverings, if possible, should be applied in preference to fire-heat.
American Plants, &c.--Pot, if not done, Rhododendrons, Kalmias, hardy
Azaleas, Lily of the Valley, and other plants usually required for
Chrysanthemums.--They will require an abundance of air to prevent the
flowers expanding weakly. Keep them well supplied with water, and the
leaves in a healthy state; for a great portion of their beauty depends
upon so doing. They may sometimes be seen almost entirely denuded of
leaves when in flower, which considerably detracts from what should be
their ornamental appearance in the greenhouse or conservatory.
Primroses (Chinese).--Give a few of the strongest and most forward a
shift into larger pots. The double varieties are very useful for cutting
where bouquets are much in request, as they do not drop the flowers like
the single varieties.
STOVE AND ORCHID-HOUSE.
Great caution will now be necessary in the application of atmospheric
heat and humidity, as an excess of either will cause a premature and
unseasonable growth which no after-care could thoroughly rectify. The
thermometer for the majority of stove plants need not at any time of the
day exceed 60 deg., with a fall of 8 deg. or 10 deg. during the night.
Begonias.--They deserve a place in every stove, as they are plants of
easy cultivation, and bloom at a season when flowers are scarce; they
can also be introduced to the conservatory or sitting-room when in
Hotbeds.--Keep up the heat of dungbeds by adding leaves and dung to the
linings; but not sufficient of the latter to cause a rank steam in the
Peaches.--If any vacancies occur in the late houses they should now be
filled up. We have before recommended trees of large size to be taken
from the walls for this purpose, but in so doing care should be taken
to select such sorts as the Murray, Elruge, and Violette Hative
Nectarines; Noblesse, Royal George, Grosse Mignonne, and
Chancellor Peaches, being the best adapted for forcing. Some sorts are
of little value as forced fruit, although they may bear abundantly.
Pines.--Coverings to be used, and as little fire-heat as possible,
to keep up the required heat during the night. The heat of the
spring-fruiting and succession-houses to be gradually decreased, so
that it may range from 60 deg. to 65 deg.. The winter-fruiting plants to
range 10 deg. higher.
Vines.--The Grapes will require unremitting attention to keep the
house dry, and to cut out the decayed berries. It will, we suppose, be
generally observed that the fruit that was ripe before wet weather sets
in will keep better than the more backward ones, which may be a useful
hint "to make hay while the sun shines," or, in other words, to
ripen the fruit in good time. Prune and dress the Vines in the
succession-houses as recommended for the early ones. When Vines
have been taken out of the house they should be protected from the
vicissitudes of the weather, as they are sometimes greatly injured by
being exposed to excessive wet and severe frosts.
