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 death.
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 foliage.
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.
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 insects.
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 and potted.
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° to 60° by night, ranging from 75° to 80° by sun heat, and
allowing 65° by artificial heat, on dull days.
Pines.—A day temperature of 75° to 80° 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.
As the boisterous gales and violent showers that frequently occur at
this season, succeeded by intervals of mild weather and brilliant
sunshine, are frequently difficult to deal with, constant attention
is necessary that a free admission of air, when in a genial state,
may be given, and the cold, cutting east or north-east winds
excluded. Frequent watering will also be necessary, and fires to be
dispensed with, or only used occasionally, merely to ward off the
rigour of sharp nights. The plants in good health, and well rooted,
to receive a liberal shift. All plants when shifted to be
accommodated with a little extra heat and moisture in the atmosphere
until they begin to make fresh roots, when they will require to be
more freely exposed, to produce a sturdy, vigorous growth.
Camellias.—The plants that have finished flowering to be removed
to a higher temperature, where a moist atmosphere is kept up by
frequent syringings.
Cinerarias.—Tie out the principal shoots of the most forward, to
form handsome plants. Manure water of the temperature of the house
to be given occasionally. The more backward to be shifted into
larger pots as they may require them, and all to receive plenty of
air, light, and room.
Fuchsias.—They require to be accommodated with a warm, moist
temperature, both at top and bottom, and the free use of the
syringe, to make them large pyramidal specimens.
Pelargoniums.—Attention to be paid to their training, to watering,
and to the admission of air. Shift on young plants, and stop all
that may be wanted for late blooming.
Finish the shifting of all specimen plants in the stove as soon as
possible. A brisk, growing, moist temperature to be kept up during
the day, and to shut up early. They delight in a tan-bed where the
bottom heat ranges from 70° to 80°.
Orchids will now require a regular looking over. Those on blocks of
wood with moss should have the moss renewed, and fresh turf to be
supplied to those in pots in a growing state.
The general routine in these structures will comprise disbudding,
tying-in advancing shoots, thinning the fruit, watering, syringing
morning and evening, airing, and shutting up early with plenty of
solar heat; and to be each and all attended to in good time to
obtain satisfactory results.
Cherries.—Caution in the application of water is now necessary, as
either too much or too little will cause the fruit to drop.
Cucumbers.—The heat of the beds, which will be found to decline
rapidly during cold winds, should be kept up by fresh linings; and
air to be given daily, to allow the superfluous moisture to escape,
taking care to prevent the wind from entering the frames by placing
a mat or canvass before the openings.
Figs.—A free supply of water, with liquid manure occasionally, to
be given to the most forward crop. Where there is the convenience,
the trees in pots are generally placed in a pit of rotten leaves
into which they root, and where they are allowed to remain until
they have borne their crops and ripened their wood, when the roots
are cut back to the pot. Trees planted out succeed best when confined
in brick pits, where short-jointed fruitful wood is produced
without root pruning, which is necessary when the roots are allowed
to ramble without control.
Melons.—This is a good time to ridge-out plants, as the sun will
have a powerful and beneficial influence at the time when it will be
most wanted to ripen off the fruit. Pot off young plants, and sow
seed for a succession.
Pines.—Continue to keep up a regular and moist heat; to be
supplied with soot or other manure water occasionally during the
whole time they are swelling the fruit until they attain their full
size; watering and syringing overhead should be withheld when they
begin to change colour, to give flavour to the fruit. The
succession-plants recently potted to be very moderately supplied
with manure water, and in a very diluted state until their roots
reach the sides of the pots.
Strawberries.—Introduce succession-plants under glass, according
to the demand. Keep the atmosphere dry when the plants are in bloom
and near the glass; admitting at all opportunities a good supply of
fresh air without currents.
Vines.—Persevere in thinning the bunches, as it is a mistake to
leave more on the Vine than it is likely to finish off to
perfection. The borders to be examined that a gentle warmth may be
maintained at the roots. When the Vines are planted inside, apply
good soakings of manure water occasionally. Thin the shoots of the
late Vines as soon as the bunches are perceptible.
Proceed as diligently as possible with the repotting of such of the
hardwooded greenhouse plants as require it, so as to start them in
good time to acquire a vigorous growth.
Cacti.—The chief point in managing these plants is to allow them
an alternate period of rest and growth. To be grown in a mixture of
lime rubbish and loam, with a little cowdung, and in well-drained
pots. In summer to be fully exposed to the sun, and well watered;
and from October to March to be kept perfectly dry.
Calceolarias (Herbaceous).—To be shifted into larger pots in a
compost of equal quantities of decayed turf, leaf mould, good sandy
peat, old cowdung, and silver sand, with plenty of drainage and moss
on the crocks. To be kept close for a week, after which air may be
freely given, avoiding currents of cold air.
Heaths.—Every vigorous shoot that is taking the lead to be
stopped, to produce a more uniform and compact plant.
Lilium lancifolium.—To be potted either in a good peat, with a
little silver sand, or in a light sandy loam, using also some silver
sand. The bulb to be placed two or three inches deep from the top of
the pot to allow room for the stem-fibres to penetrate the soil.
Pelargoniums.—The plants potted last month to be stopped back. The
house to be kept rather close for a week or ten days, to assist them
to push out their eyes. Those intended to bloom in May, that have
not been stopped since cutting down, will be putting up their
trusses, on sunny days syringe them lightly, and shut the house up
warm, with the sun upon it, about three or four o’clock in the
afternoon.
Keep a lively growing temperature here during the day, with a
plentiful supply of moisture. Syringe, and shut up early, with 80°
or more, allowing a fall of 20° during the night. Shake out and
repot in succession the stove plants that have been previously
recommended to be headed back, and encourage a free growth by
plunging them, if possible, in bottom heat. Smaller pots to be used
until they have filled them with roots, they may then receive one
bold shift that might probably be sufficient for the season.
Cherries.—These may now want thinning if too thickly set; but the
operation must be influenced by the energies of the tree and the
action of the roots. Endeavour to keep the atmosphere like fine
mild weather in May. During the period of the stoning of the fruit,
give the trees no water at the roots, as this is generally one of
the chief causes of so much of it falling off at that time.
Figs.—When the fruit is swelling off, the trees to be liberally
supplied with water. The young shoots to be stopped to four or five
eyes, with the exception of those that are required to fill up
vacancies.
Melons.—Continue the thinning, stopping, training, &c., as
required. Set the early crops when in blossom, keeping a dry and
lively atmosphere during that period. Air to be given freely in
favourable weather, but cautiously, with some contrivance to break
cold winds. Do not allow a plant to swell a fruit until sufficiently
strong to sustain it.
Peaches.—Be moderate in the application of fire heat to those that
are stoning (they make little or no progress in swelling during the
period)—say 65° by day and 60° by night; but when they commence
their second swell increase the heat moderately. Stop all luxuriant
shoots, and thin out in the second house all clusters of fruit when
about the size of Peas.
Pines.—The fruiting plants will be benefited by a watering with
manure water as soon as the bloom is set. Succession plants, if
recently shifted, to be shaded in the middle of the day if the sun
is powerful; to be kept rather close and dry, except slight
sprinklings over the tops, until they have taken root, when they may
be watered freely, and will generally require no more to be given
for a week or ten days.
Vines.—The atmosphere in the early house, where the bunches have
been thinned, to be kept pure by a gradual increase of air and
moisture. The night temperature to be kept up to 65°, with an
increase of 10° by day, and even more in bright sunshine. The second
house may now be in bloom, and will require attention in tying the
shoots and keeping up the necessary amount of heat, with less
moisture. Where the fruit is set, give the Vines a good syringing,
to wash off the flowers; after which the leaves and fruit should not
be again wetted, but to be supplied with atmospheric moisture by
watering the floor of the house, and sprinkling the flues or pipes,
or from evaporating-troughs or pans. Give plenty of tepid manure
water to the Vines fruiting in pots.
As the great proportion of greenhouse plants are now commencing, or
are in active growth, constant attention will be required for the
judicious regulation of temperature, and for the admission of fresh
air during fickle and ungenial weather, and in the supply of water
to the roots, and atmospheric moisture.
When settled fine spring weather has arrived, every plant which
inhabits a pot should be brought at once under review, and put in
proper condition for the growing season. No fear need then be
apprehended from potting. Keep up a moist atmosphere by sprinkling,
&c., and admit plenty of air, bearing in mind former directions as
to draughts, &c. If the plants in the borders, or any of the
climbers, are dry, give them a good soaking of weak, tepid manure
water. Trellis climbers to be frequently attended to—stopping,
training, and arranging their shoots.
Balsams.—Encourage the growth of them and other such tender
annuals by potting them when the roots begin to cluster round the
side of the pot.
Calceolarias (Herbaceous).—Shift on the young stock, keeping the
plants well down in the pots, so as to bring the earth in the pots
up to the lowermost leaves, to induce the plants to throw out fresh
rootlets from the stem. Keep a sharp look out for green fly.
Climbers.—Prune off superfluous shoots; stop or pinch out the tops
of gross leaders, and keep them neatly tied and trained.
Cockscombs.—To remain in small pots until they begin to show
flower.
Dahlias.—Pot off cuttings as soon as struck.
Fuchsias.—Continue to shift young plants into larger-sized pots,
according to their height and strength; to be kept growing by
placing them in a brisk, moist heat. Cuttings to be potted off as
soon as they are sufficiently rooted; to be placed in a temperature
similar to that in which they were struck.
Sow in heat seeds of stove and greenhouse plants.
Attend to regular shifting, watering, and a free and healthy
circulation of air, without draught, early in the morning to stove
plants. Continue to cut down, disroot, and repot, as advised last
week, those which have been flowering through the winter. To be then
favoured with a bottom heat of from 75° to 80°, and slightly shaded
during bright sunshine.
Some of the young plants in the stove which are growing on for
specimens will probably require a second shift, see to them in time;
and if they are in good health treat them liberally by giving a
large shift, especially to plants of free growth. Give plenty of air
at all favourable opportunities, and saturate the atmosphere with
moisture. The surface of the tan to be stirred once or twice a-week,
and sprinkle it occasionally with manure water, to produce a moist,
congenial atmosphere about the plants. Shut up with plenty of sun
heat. Look sharply after mealy-bug and thrips.
Achimenes.—The plants established in small pots may be removed
into the flowering-pans, putting six plants into a pan.
Orchids.—Increase the temperature, and ply the syringe among them,
as they will now grow rapidly. Be careful not to throw too much
water over those sending out succulent flower-stalks, for they may
damp off. Ferret out and destroy cockroaches, woodlice, and snails.
Calantha veratifolia, Neottia picta, N. elata, Phaius of
sorts, some varieties of Stanhopea, Zygopetaltum Mackayii, and
other such Orchids that are now making their growth, would be
benefited by an application of clear, diluted manure water
occasionally; a kindly humidity to be kept up, and the shading to be
in readiness for use during bright mid-day sun.
Sow tender and half-hardy annuals; pot off those already up; give
air daily, and never allow the plants to flag for want of water. Pot
off cuttings of Dahlias, and continue the propagation of Fuchsias,
Heliotropes, Petunias, Verbenas, and bedding-plants generally.
Beans (French).—Give them, when in a bearing state, a liberal
supply of manure water, and see to keeping up a succession of them.
Cherries.—When you are sure that the fruit is finally stoned, the
temperature may be raised a few degrees; air and water overhead to
be liberally supplied.
Cucumbers.—As soon as the frames are uncovered in the morning give
a little air for an hour, to let the stagnant and foul air pass off,
when they may be closed again till the day is further advanced. As
soon as the principal shoots have reached the side of the frame,
never allow any of the laterals to grow more than two joints before
being stopped. Stop frequently, and thin liberally; where two fruit
show at a joint pinch one away.
Figs.—If red spider should be observed, wash the flues or the
walls exposed to the sun with lime and sulphur.
Melons.—Those lately planted out to be encouraged with a close,
moist heat, to get them into free growth as quickly as possible. The
plants that are fairly established to be kept cooler, admitting air
at every favourable opportunity, to produce short-jointed fruitful
wood. The shoots to be kept thin and regular, pinching out any that
are not wanted. The night temperature not to exceed 65°, and air to
be admitted as soon as the thermometer rises to 75°; but to be given
very cautiously during cold winds. Prepare for raising plenty of
young plants for succession crops, and endeavour to have them strong
and vigorous by keeping them near the glass; to be provided, when
they require it, with plenty of pot-room. Keep up the heat in the
beds by renewing the linings; the coverings at night to be regulated
in accordance with the heat of the beds, taking care that the mats
do not hang over either the front or back of the frames.
Mushrooms.—Collect materials for fresh beds, and give those that
have been some time in bearing good soakings of manure water;
sprinkle the floor and heating apparatus occasionally. The
conditions of success are to have the materials for making the beds
well prepared and sweet—that is, free from rank steam, and the
spawn to be put in whilst the heat keeps regular and moderate, and
the beds are coated over to keep it so until the spawn is well
established.
Peaches.—Remove all superfluous shoots, and tie in neatly those
that are left; thin the fruit that is swelling off before stoning,
leaving more than may be ultimately required, as, in stoning, it is
liable to drop off. Syringe the trees daily in fine weather. Where
it is intended to force Peaches, Cherries, &c., in pots next season,
and some suitable trees have to be provided, it should be no longer
postponed. It is a good plan to pot some maiden plants every year,
to succeed any that may become useless.
Pines.—Give plants swelling their fruit plenty of manure water,
and a humid atmosphere. The fruiting-house may range from 80° to 85°
during the day, and as near 70° as possible at night; the
succession-pits from 75° to 80° during day, and 60° to 65° at night.
These particulars to be modified by the state of the weather,
whether sunny or dull.
Strawberries.—They require plenty of light and air to set their
fruit, when they may be removed without fear of injury to a stove,
or any other house or pit possessing a higher temperature. The
plants swelling their fruit require a liberal supply of water, and a
sprinkling overhead daily. When the fruit begins to change colour
the sprinkling to be dispensed with, and the supply of water at the
roots to be given sparingly.
Vines.—If the Grapes are colouring, a free circulation of air,
accompanied with a high temperature, will be advantageous. Attention
to be given, where fermenting materials have been used for warming
the borders, that the heat is not allowed to decline at present
under the influence of the March winds. Attend to last week’s advice
as to tying, disbudding, &c., and proceed with the thinning the
fruit in the succession-house as soon as the berries are fairly set.
When thinning be as careful as possible of the bunches—neither
pull them about with the hand, by which rust on the berries is
frequently produced, nor with whatever the shoulders may be held up
by at the time of thinning, as, by the twisting of the stalks,
shanking is not unfrequently produced. Attention to be given in
stopping all laterals, and breaking off all useless shoots for the
more free admission of light, which is most beneficial in every
stage of their growth. Look over houses where the fruit is swelling,
and see if any of the bunches would be improved by tying up the
shoulders. Any healthy Vines, but not of good kinds, should be
inarched before the wood gets too old.
