Part 6
Heaths.--If mildew appears, dust them with flowers of sulphur. When watering, give them a good soaking, so that every part of the ball is thoroughly wet, and then withhold further supply until it is again completely dry.
Japan Lilies.--As they are succulent in growth, keep them well and liberally supplied with water. The flower-stems to be properly sticked, so as to keep them in due bounds, and also to assist in presenting a large mass of flowers to the eye at once.
Pelargoniums.--If the plants have been exposed to the open air, as advised in a previous calendar, they will now be fit to cut down. After the plants are cut down, place them in a shady place until the most forward young shoots are one inch long; then shake them out, and repot into small pots, using sandy loam and peat only, and placing them in a close, cold frame until they begin to grow again; after which freely expose them to the weather until heavy rains in autumn, or the approach of frost, renders it necessary to house them for the winter.
STOVE AND ORCHID-HOUSE.
Cleanliness is indispensable amongst the Orchids, use a sponge to remove filth from the leaves. See that no plants are neglected in standing in corners or behind large plants; arrange and re-arrange frequently, as it tends both to promote the healthy growth of the plants and a pleasing variety in the house.
FORCING-HOUSES.
Cucumbers.--Although bright hot weather may prevail, it is advisable to keep up a brisk, regular bottom as well as top heat. Strike cuttings of choice sorts for winter bearing.
Melons.--The same as advised for _Cucumbers_, as they both delight in plenty of heat to keep them healthy and in regular bearing. Give them good soakings of weak manure water occasionally, and shut up early on all fine days, sprinkling the sides of the pits or frames, and the plants at times overhead. When watering the plants never allow any to fall on the main stem. If gum, or canker, appears, apply lime to the parts affected. Old plants cut back should be stimulated to grow freely.
Peaches.--Any tendency to premature decay in the leaves of those from which the fruit has been all gathered to be arrested by liberal waterings at the roots and by syringings.
Pines.--Keep up the temperature from 90 deg. to 95 deg. by day and from 70 deg. to 75 deg. by night, with plenty of moisture among the growing plants and swelling fruit. Shift the successions as the roots fill the pots.
Vines.--Uncover the house, or give all the air possible night and day as soon as the Grapes are gathered, unless the wood is not fully ripened, in that case the house should be closed in the afternoon at a good heat. Stop the laterals on the later Vines, thin and tie up the bunches, and maintain a steady, moist temperature, with plenty of air, but do not syringe the bunches.
THIRD WEEK.
GREENHOUSE AND CONSERVATORY.
If any of the stove plants, as lately recommended, have been brought into the conservatory, they will require a free admission of air at every favourable opportunity to keep the atmosphere of the house dry. The plants must be kept clear of decaying leaves and flowers. Some judgment is also required in watering recently repotted plants, that they may not be injured by saturation in cloudy weather, nor by drought in hot sunny days.
The growth of twiners should be carefully regulated, allowing them sufficient freedom to develope their natural habits as far as other considerations will permit.
Continue to shift the hardwooded plants as they require it. A turfy compost of three-parts sandy heath soil of a fibrous and rather lumpy character, and one-part loam, will suit the majority. Particular attention should be paid to the drainage, more especially to the crock at the bottom; for if that is flat, and not hollow, it matters but little how much depth of drainage material rests upon it, the soil will soon become saturated and sour. Remember that the final shift should be given in good time to those intended to flower in the autumn.
Calceolarias (Herbaceous).--Sow seeds; the compost to be equal parts of peat or leaf mould, loam, and rotten dung, with a small portion of sand. Place a layer of broken crocks two inches thick at the bottom of the pot; then fill up within half an inch of the rim with the compost, passed through a fine seive. After the pot has been gently struck on the potting-bench to settle the soil, the surface must then be made level with a flat piece of wood, or the bottom of a small garden pan or saucer. Sprinkle the seeds regularly over the surface, do not cover with soil, and water with a fine rose; then to be placed in a cold frame, and be kept shaded from the sun.
Chorozema.--The beauty of this genus for early spring display is generally appreciated, and, therefore, requires no commendation from me. They delight, like most other New Holland plants, in sandy peat containing plenty of fibre, and require plenty of air at all times, and also to be kept constantly moist, but never very wet. A large pot and frequent stopping will soon produce a fine specimen.
Chrysanthemums.--Continue to top the plants that have been planted out in the open ground.
Epacris.--The varieties of this genus are most useful for the adornment of the conservatory in early spring. They delight in fibrous peat, broken rough, mixed with fine white sand. The young plants to be frequently stopped by pinching off the points of the shoots while growing, to induce them to throw out laterals; those again to be stopped until the plants have attained a size sufficient to warrant their blooming.
Gardenias.--If any have been removed to the conservatory while in bloom they should be returned to heat as soon as the bloom is over, to encourage growth and to allow them sufficient time to mature their growth.
Eutaxia myrtifolia.--It is a profuse and early bloomer. During the summer and autumn every new shoot should be stopped as soon as it has attained two or, at most, three joints: by such treatment it can be easily formed into a neat, compact specimen.
Winter Flowers.--The Cinerarias, Chinese Primroses, Heliotropes, Perpetual, Tea, and other Roses, will require frequent and diligent attention as to watering, shifting, &c.
STOVE AND ORCHID-HOUSE.
Give immediate and regular attention to the young stock of stove plants intended for winter blooming. Keep up a moist temperature at all times; with air during the day. When a few days of gloom occur, the humidity that sometimes becomes stagnant and injurious should be dissipated by a free circulation of air when bright weather returns. Keep a free circulation of air amongst the Orchids by day; endeavour to supply an abundance of atmospheric moisture during the latter part of the day; and dispense with shading as much as possible by using it only during a few hours of the hottest part of the day.
Pay every attention to specimen plants in the stove. Keep them neatly tied to sticks, or trellises, as the case may require. Give them a plentiful supply of water, and, if not in flower, syringe them frequently overhead.
Stanhopeas.--About the end of this or the beginning of next month is the most proper time to remove and repot them. Persons who wish to grow fine specimens ought to put them in large baskets, or pots, so that they may not require to be shifted for several years, as then the plants grow much finer and flower better than when annually shifted. Now, as soon as they have done flowering they commence growing, when they should have plenty of heat and moisture until they have completed their pseudo-bulbs, when they should be reduced to a comparative state of rest by gradually withholding water until they show flower; then to be supplied with atmospheric moisture, but should have no water at the root, or at least but a small portion, until they begin to grow. As all the plants belonging to this genus push their flowers downwards, it is advisable to have them elevated, or put in baskets, where the flowers can get through and show themselves to advantage.
FORCING-HOUSES.
Figs.--Supply with plenty of water the roots of the trees that are swelling their second crop; ply the syringe frequently amongst the foliage, and sprinkle the paths, &c., to keep the atmosphere moist. Shut up early in the afternoon. As the fruit of the first crop ripens, curtail the supply of atmospheric moisture--otherwise before they reach maturity they are apt to turn mouldy. The roots to be regularly supplied with water, and some liquid manure added about once a week to assist the second crop. Keep down red spider by the application of sulphur in the manner so frequently advised of late. Give the fruit that is ripening the benefit of the sun, by fastening on one side the leaves that shade it.
Peaches.--The fruit will be all the more delicious for a comparatively cool temperature while ripening. Examine the fruit daily, and gather before it is overripe and loses its flavour.
Pines.--Maintain a good bottom heat, and encourage the growth of the advancing crop by kindly humidity and allowing them plenty of air and sufficient space from plant to plant. Give air, also, freely to the young stock in dungpits, to secure strong stocky growth; but a circulation should not be allowed by giving back and front air at the same time during hot drying winds. Attend to former directions to afford the plants swelling their fruit a moist atmosphere by frequent syringings and by sprinkling the paths and every other available surface until the fruit begins to change colour, when the atmosphere and soil should be kept rather dry, to improve the fruit's flavour. See to the stools from which fruit have been cut. Earth them up, so as to cause suckers to strike root. Give them a brisk bottom heat, and proper supplies of water. You will thus gain time and assistance for the suckers from the declining strength of the parent plant as long as possible. It is now a good time to start a lot into fruit, as they will have two or three most favourable months for swelling, and will come in at a season when they are in very general request. Keep the bark-bed moderately moist, as in that state it will retain its heat much longer than if it is allowed to get dry.
Vines.--Keep up a brisk heat to the late Grapes during the day, as it is advisable to get them well ripened before the season gets too far advanced. By such means they will be of better quality and keep longer than if the ripening process be delayed to a later period. Do not allow plants in pots to remain in the house to cause damp, which, despite every care in ventilating, is apt to settle on the berries and spoil them. The outside borders of the late houses should be watered and mulched, if the weather continue dry.
FOURTH WEEK.
GREENHOUSE AND CONSERVATORY.
The conservatory should now be gay with Balsams, Cockscombs, Fuchsias, Globe Amaranths, Heliotropes, and the varieties of Japan Lilies. Strict attention must be paid to all plants in these structures that they do not suffer from the want of water. Continue to stop over-luxuriant growth, to obtain compact, sturdy specimens. On the evenings of hot, dry days, after the plants have been watered, give them a slight syringing, or sprinkling, over the leaves, and also the ground upon which they are standing.
Aotus gracillimus.--When done blooming, to be cut down close to the pot.
Aphelexis and Helichrysums.--When past their best state, cut the flower-stems close into the old wood; to be set in a cool shady place until they begin to grow, when any that require it may be repotted.
Chrysanthemums.--Propagate by cuttings, or layers, to obtain dwarf stocky plants. Continue to top the plants that have been planted out in rows in the open ground, as advised some time ago.
Cinerarias.--Pot off the first batch of seedlings and offsets. Sow seed.
Fuchsias.--Shift in the last batch, and put in cuttings.
Leschenaultias.--When they are going out of bloom, or past their best, remove the flowers and flower-buds, and put them in a cool place to start again.
Kalosanthes.--When done blooming, the flower-stems and all straggling growth to be cut in closely, to form compact specimens for another season.
Pelargoniums.--Cut back the principal stock, and treat them as advised lately.
Pimelea spectabilis.--When that and the other kinds have done blooming, to be freely cut in, and to be set in a cool shady place to break.
Polygalas to be treated in the same manner as the _Pimeleas_.
STOVE AND ORCHID-HOUSE.
Look out for insects in the stove, and destroy them as soon as visible. The _Gishurst Compound_ is worthy of a trial. Follow former instructions as to moisture and air.
Ixoras.--When done blooming to be cut in rather closely, to be started in a gentle heat to make fresh growth. The Orchids suspended on baskets, or on blocks of wood, require a soaking of water at the roots, and frequent, but slight, syringings overhead. A little fire-heat applied in the afternoon will be of service to them.
FORCING-HOUSES.
Figs.--If the second crop on the earliest trees is advancing towards maturity, as soon as the fruit begins to ripen the atmosphere should be kept dry and rather cool, giving air freely every fine day. Keep the foliage clean and healthy, and clear from insects, and do not allow the young shoots to get crowded.
Melons.--Keep up a good bottom heat when the fruit is setting. Keep the plants on which the fruit is ripening rather dry at the root, with an abundance of air in fine weather.
Pines.--Air to be admitted freely during hot weather to fruiting and succession plants. Particular care will be necessary in the application of water that they may not suffer for want of it, or by saturation. The walls, paths, and surface of the bed to be kept constantly moist, and frequent syringings to be given to the young stock. Continue all other routine operations according to former directions.
Strawberries.--Some lay the runners at once into pots of strong, rich loam, cutting them away from the parent plants when they have made roots enough for their own support. Some prefer to lay them in small pots, to be shifted into larger by-and-by, and others prefer to lay them in their fruiting-pots. The principal object should be, to attain plants of a moderate growth, well matured and rested before forcing time.
Vines.--The early houses, when they have been cleared of their fruit, and the wood is properly ripened may have the sashes removed and repaired, if required; indeed, every house is purified by free exposure to the atmosphere for some time. The late crops to be encouraged to swell by giving the borders good soakings of manure water, and by being carefully thinned, more especially if they are wanted to keep late. A little fire-heat will be necessary in unfavourable weather, with an abundance of air day and night.
AUGUST.
FIRST WEEK.
GREENHOUSE AND CONSERVATORY.
The conservatory borders will now require liberal supplies of water. Faded blossoms to be constantly removed; straggling growth and exhausted stock to be cut previous to making a new growth. As the autumn is fast approaching, the sooner the new growths are encouraged the better, that they may have sufficient time to mature them. All greenhouse plants will now be benefited by exposure to the natural atmosphere: the dews are more refreshing and invigorating than artificial moisture or the application of the syringe.
Finish _potting_ all specimen plants; for if left until later in the season they will not have sufficient time to fill their pots with roots, and, therefore, will be liable to suffer from stagnation of water at the roots. No position can be worse for a plant than that of surrounding it with fresh soil for months when the roots should be in a comparatively dormant state.
Pelargoniums.--Continue to head them down, and to propagate the cuttings, which will now strike freely in a sunny situation in the open ground.
STOVE AND ORCHID-HOUSE.
Much moisture and free ventilation will be necessary here during warm weather. The young plants of Euphorbias, Ixoras, Poinsettias, and other such stove plants, to be rendered bushy by stopping them betimes. The _AEschynanthus grandiflorus_, _Aphelandra cristata_, _Eranthemum pulchellum_, Justicias, and any others that are intended for the decoration of the conservatory in the autumn and early part of winter, should be carefully looked over, and shifted without delay if they want more pot-room; the shoots to be tied out thinly, and to be exposed to as much sun as they will bear without scorching the foliage, to induce stocky growth. Nothing is more injurious to stove plants than to keep them growing late in the season, and thus to prevent the ripening of the wood, which will render them more liable to injuries in winter and more unproductive of flowers the following season.
FORCING-HOUSES.
Melons.--The plants on which the fruit is ripening to be kept rather dry at the roots, with free exposure to the air in favourable weather. A steady bottom heat to be kept up to the late crops.
Peaches.--If the lights have not been taken off the early-forced houses, it would be advisable to remove them as soon as possible, that the air, rain, and dews may have free access to act both beneficially on the trees and to keep down red spider. In those houses which have been treated as advised in former Calendars, the principal object now should be to get the wood properly ripened. The late houses to be treated in a similar manner when the fruit is gathered. Where the trees in peach-houses have been recently planted, and are not yet in a bearing state, the shoots will require to be trained carefully, and insects to be kept down.
Pines.--The plants growing in beds of soil to be carefully attended to with water, giving at each application sufficient to penetrate the whole body of soil, as it frequently happens that the surface is moist while the bottom is quite dry. Pot a portion of the strongest successions for early forcing next season.
Strawberries.--Continue to lay the runners of the kinds you wish to force in pots until you have a sufficient number.
Vines.--Muscats, now beginning to ripen, will generally require a little fire heat to push them on; when ripened in good time they are better flavoured and keep longer than when the ripening process is delayed to a late period of the season. Continue to remove the stray laterals that begin to shade the larger leaves; to be done a little at a time, as disbudding on an extensive scale is prejudicial to fruit trees. The young Vines in pots to have every attention, to secure as much growth and healthy vigour as possible while the growing season lasts. Allow all young planted Vines to ramble freely without stopping them so closely, as is frequently practised. Before wasps and flies do much mischief to ripe Grapes, coarse canvass should be fixed over the top lights and front lights that are opened for the admission of air. Remove decayed berries as soon as observed, and keep the house containing ripe fruit dry and free from dust.
SECOND WEEK.
GREENHOUSE AND CONSERVATORY.
Bulbs.--The selections for winter and spring flowering to be made as soon as possible, choosing the most suitable varieties for each season; to be potted at two or three intervals for succession. To be potted in light fibrous turfy loam of a sandy quality, and placed in a dry situation; to be covered with three or four inches of old tan or coal ashes.
Camellias.--The large, old specimens that have set their flower-buds to be carefully supplied with water; for if they are allowed to get too dry at the roots they are apt to drop their buds. Young vigorous plants, on the contrary, will require to be watered rather sparingly, to prevent them making a second growth.
Cinerarias.--Shift as they require it, and let no neglect as to watering, &c., cause a check to their growth.
Climbers.--To have a succession late in the season when flowers become scarce, it is advisable to cut them back for that purpose, more especially the climbers on rafters or ornamental trellises.
New Holland Plants.--If any have been standing out of doors for some time, it is advisable to remove the best and most tender varieties to the cold pits, or other secure situations, to avoid the danger and risk of exposure to wet or windy weather.
Soils.--Now is a favourable time to collect soils of different sorts for future use. The advantages of forethought for such matters will become evident when the time for use arrives. Leaf mould, decomposed sheep, deer, and cowdung, road and river sand, old Cucumber, Melon, and other such soils, to be put in separate heaps in a shed, or any other dry place, protected from drenching rains. Each sort to be numbered, or named, that no mistake may occur when wanted.
STOVE AND ORCHID-HOUSE.
All plants intended to flower this autumn to be regularly supplied with water and occasionally with liquid manure; but all the other stove plants to be watered more sparingly after this time, and the water to be given early in the morning. The house to be shut up early in the afternoon with a strong sun heat. Slight fires to be made in the daytime, if the weather is dull, so that plenty of air may be given to the plants.
FORCING-HOUSES.
Figs.--If the nights are cold, the house or pit should be closed early, for the benefit of the second crop of fruit.
Melons.--Withhold water when the fruit is ripening, as a sudden supply at that time very frequently causes the fruit to crack and become worthless. Keep the shoots so thin that every leaf may receive the benefit of the light. Do not expose the fruit to the sun's rays till it is fully swelled. Give a supply of manure water to the late crops, and thin out useless laterals. It is advisable to paint the interior of the frame, or pit, with sulphur: this, with slight syringings and shutting up early while the sun shines upon it, will keep down insects.
Mushrooms.--Collect some very short stable-litter and horse-droppings, and turn them over frequently with the addition of a small portion of turfy loam until they are well incorporated. When moderately dry, to be packed on shelves or in boxes, and be well-beaten down in layers four or five inches thick, till the bed is the required thickness--from a foot to eighteen inches; for success will depend in a great measure upon the solidity of the bed. To be spawned when there is a brisk heat.
Pines.--If a strong body of fresh materials have recently been added, the watch-sticks should be frequently examined, and any approach to a burning heat to be counteracted by lifting the pots, &c. Fruit recently started and swelling off to have every encouragement for the next two months. Shut up early, to secure a strong amount of solar heat. Keep all the growing stock warm and moist, syringing them lightly twice a-day.
Vines.--The early-forced houses, where the wood is nearly ripe, would be benefited by free exposure to the air; but if the lights are required to remain on, cleanliness should be observed, and all laterals kept down. When the fruit is swelling or colouring, and when the weather is wet or cloudy, a gentle fire, if then applied, will expel damps, and be in other respects very beneficial to them. Stop all useless growths in the late houses; do not remove the leaves to expose the fruit to the sun, unless they are very thick indeed, as they are the principal agents by which nutriment is carried to the berries.
Vines in Pots.--When the leaves begin to fade, to be removed to the north side of a wall, and the pots to be laid on their sides, to keep the roots dry. A little litter thrown over the pots will protect them from sudden changes.
THIRD WEEK.
GREENHOUSE AND CONSERVATORY.
