Hot-House

FEBRUARY

In the early part of this month the weather generally is very cold and changeable in the middle states, and strict attention, with the greatest caution, will require to be paid to the management of the Hot-house. Most of the tropical plants commence an active state of vegetation; and if checked by temperature or otherwise, they will not recover until midsummer. The thermometer may be kept two or three degrees higher with fire heat than last month; the sun will be more powerful, and this will, in a great degree, increase the vigour of the plants. Air may be admitted when the thermometer rises to 75° or 80°, not allowing it to rise higher than the latter. In giving air, let it be done by the top sashes. It is improper to give it in any way to cause a current, for the external air is very cold, although the sun is more powerful. An inch or two on a few of the sashes, as has been previously observed, will be effectual in keeping the temperature low enough, except the weather is very mild.

With regard to firing, what was said last month may suffice for this. Always recollect that it is preferable to keep out the cold than to put it out. It will frequently happen in the time of intense frost, that the weather is dull. In such cases fire in a small degree is requisite all day.

Heavy snows ought never to be allowed to remain on the shutters while they are on the house. If the snow lies on the sashes one day, the internal heat will dissolve some of it; night coming on will freeze it to the wood work, when it will become a solid mass, and too frequently cannot be separated without much damage. If allowed to remain on for two days, the plants are very much weakened, and the foliage discoloured. Therefore let the snow be cleared off instantly, that no inconvenience may take place.

It will be observed that plants absorb more water this month than last. The quantity given will require to be increased, according to the increase of vegetation and the advancement of the season; but never give it until the soil begins to get dry, and then in such proportion as will reach the bottom of the pot. After the sun has got on the house in the morning is the best time to water, observing all the directions given in January.

OF INSECTS, &c

Perhaps sufficient observations were given under this head last month; but the importance of keeping these disagreeable visitors out of the house, constrains us to make a few more remarks, and perhaps it may be necessary every month. Man cannot be too frequently guarded against his foes, more especially when they are summoning all their forces, and no profession has more than that of the Horticulturist. Let a strict examination be made about the end of the month for the Red spider; they will be in operation some weeks before their depredations are observed on the foliage. The under side of the leaf is their resort in the first instance, and on such plants as have been already mentioned.

Observe daily the young shoots, in case the Green fly becomes numerous. They give the foliage a very disagreeable appearance, and with most people it is intolerable, before their career is arrested. It also takes a stronger fumigation, which has frequently to be repeated the following day to the same degree, much to the injury of many of the plants, and adding to the disagreeableness of the continued vapour in the house.

OF SHIFTING PLANTS

The Calceolàrias that were put in small pots about the beginning or middle of last month, will, if they have done well, require, about the end of this, to be put in pots a size larger.

If any of Lilìum longiflòrum, Speciòsum, or Japónicum, are wanted to flower early, and were put in the Hot-house in December, without dividing, those that are to flower will have pushed their flower stems, and can be separated from those that will not flower, and put singly into pots; the two former into five or six inch pots, while the latter require six or seven inch pots. Of those that do not flower, three or four can be put into one pot.

About the end of the month, some of the plants of Eurcúma, Amómum, Kæmpféria, Glóbba, Phrynium, Cánna, Zíngiber, Hedychium, and others that are on the dry shelf, will be offering to grow. Let them be taken out of their pots, some of their weakest shoots or tubers taken off, and the strong ones repotted: give gentle waterings until they grow freely, then give an abundance.

Dionæa mucípula, or Venus fly trap, grows best in the Hot-house, and will, about the end of the month, stand in need of being repotted. This plant is very seldom grown in any degree of perfection, having been always considered a delicate plant in collections. The operator has never had courage to treat it according to its nature in a cultivated state. If it is taken out of the pot, just when beginning to grow afresh, and divested of all the soil, leaving only a few of the young roots, (it is a bulb, and will receive no injury by so doing,) put it in new soil; when potted, place the pot in a saucer with one inch of water in it, giving always a fresh supply, when necessary. A shady and moist situation is best adapted to it; this being repeated every year, it will grow, flower, and seed in perfection.

Gesnérias, if in small pots, give larger as they advance in growth. This genus requires to be well attended to make them flower well. G. bulbósa ought to have a situation in every Hot-house. It is remarkable for its many brilliant crimson flowers, and continues in flower for a length of time. When the bulb begins to push, shake it out of the earth, putting it into a small pot; and, as soon as the roots reach the side of the earth, which will be in about one month, put it in a larger pot, and continue to do so until flowering, which will be about the first of June, observing always to keep the ball of earth entire.

Gloriósas must be repotted in the beginning of this month. Etymologists have said that this genus is named from the glorious appearance of its flowers. G. supérba is the most beautiful and curious. The roots ought to be planted one and a half inch deep, taking care not to break them; if there is a bark bed, place the pots in it. Do not water much until they begin to grow. Where there is no bark bed, put the pots into others three inches larger, filling all round with sand, and place them in the warmest part of the house. Keep the sand moist, which will assist to keep the soil in a moist state. The earth must not have much water. As the plants grow, they will require a more liberal supply; yet it is necessary, at all times, to be moderate in giving it. If well treated, the superb flowers will appear in June or July.

OF CLEANSING PLANTS, HOUSE, &c

With regard to cleaning the plants. Sprinkling, or syringing, is at all times, to a greater or less degree, necessary. The plants will, in this compartment, be in their first stage of growth, and, if dust or foulness be permitted to lodge on their foliage, the pores will be obstructed, the plants will become unhealthy, and the growth of insects increased.

Let all moss, litter, decayed leaves, or weeds, be cleared out of the house, the earth in the pots stirred up with a round pointed stick, and fresh earth given where required, that the air may operate therein freely.

The house ought always to be sprinkled before being swept, to prevent the dust rising.

Attend to the bulbous roots as directed last month, such as Hyacinths, Narcissus, &c.

Green-House

FEBRUARY

The directions given last month respecting the airing and temperature of the house, may still be followed, differing only in admitting air more freely as the season advances, and according to the power the sun has on the glass, which now begins to be considerable.

If the weather is tolerably mild, air may be admitted in time of sunshine, so as to keep the mercury as low as 45°, but be cautious in cold, cloudy, frosty weather. It is a practice with many in such weather to keep the shutters on the house night and day, for the space of a week, and sometimes more, never entering it; and, when the weather has induced them to look in, they find that the frost and damp have made many lifeless subjects; whereas, had the house and plants been attended to, in taking off the shutters, and giving a little fire when requisite, all would have been in safety, and many that cannot be replaced still in the collection.

When watering, strictly adhere to the directions of last month, except with Geraniums, and other soft wooded plants, which require a little more water toward the end of the month. If the days are mild and sunny about eight or nine o'clock in the morning, all the plants would be benefited by a gentle syringing, which retards the progress of insects, and accelerates vegetation.

Succulents, such as Cáctus, Mesembryánthemum, Aloes, Furchræas, Crássulas, Cotylèdons, &c. will very seldom need water, at the same time keep them from getting as dry as powder.

OF ORANGES, LEMONS, &c

Similar treatment to that recommended last month will do for this. Where the soil in the tubs or pots requires to be enriched, take of bone dust or shavings, and fresh sheep dung, equal quantities; put the mixture into a large tub or barrel, until one third full; and fill it up with water. Stir it well two or three times every day for a week, then give each tree one good watering with the compound. Continue to mix up afresh, and let it stand another week, and so on until all the trees requiring it are watered. This watering will greatly enrich the soil, and invigorate the roots.

OF CAPE BULBS, &c

The bulbs, of Ferrària undulata and F. antheròsa, that were taken out of the pots in October, will now require to be planted. Five inch pots will be large enough for good roots. The grand criterion for planting bulbs is when there is a protuberant appearance about the bottom, or root part of the bulb, showing, by a principle of nature, the true time for transplanting. When bulbous roots of any description appear above ground, they ought to be placed in an airy situation. They are very frequently placed under other plants, by the inexperienced, until they show their flowers, and then brought to the light, having weak flowers, and comparatively of momentary existence.

Hyacinths, Narcissus, Gladìolus, Ixia, &c. having flower stems, ought to have support, to prevent accident, especially the two former; keep them nigh the glass, and water freely. Change the water regularly in the bulb glasses, observing that their roots are never allowed to become matted with fœtid water. Any of the above plants that are in flower, might, if desired, be taken into the drawing room or parlour, washing the pots clean, and putting saucers under them, keeping therein a little water. Twice a week the decayed ones can be taken out, and supplanted with those that are coming into bloom.

CAMELLIA JAPONICA

Will, in this month, show a profusion of flowers; and, where there is a variety, they have truly a magnificent appearance. From a good selection, endless varieties, by seed, of exquisite beauty, might be obtained by attention to the following rule. The best to select for bearing seed are Single white, Atoniana, Grandiflora, Waratah, Carnation Waratah, Fulgens, and, in many instances, the pistil, or pistillum of Variegata, Pompone, Pæoniflora, and Intermedia, are perfect, with several others. When any of the above are newly expanded, (Waratah is most perfect about one day before expansion,) take a fine camel hair pencil, and put it gently on the farina or pollen, which is a yellow substance on the anthers, and, when ripe, appears in thousands of small particles. Take the finest double kinds, then, with this on the pencil, rub lightly the stile of those intended to carry seed. Between the hours of ten and twelve in the forenoon, is the most proper time for the operation; the seed will be ripe in September or October, which will be taken notice of, and directions given. For other particulars on cleaning and syringing, see January under this head.

OF SHIFTING &c

The best time to repot Camellias, is just when they are done flowering, which will be before they begin to grow. There are, though not frequently, some flowers after the young foliage begins to appear, and probably it would be better to discriminate the time by the buds offering to push, which will answer to those that have no flowers, as well as those that have. The most general time in shifting Camellias is in August and September, indiscriminately with other plants; and, if then not very gently handled, bad roots eventually are produced. Frequently very fine plants have been killed by probing, and breaking the young fibrous roots, thus causing mortification.

In the process, do not, by any means, break, or bruise any of the roots: and do not give large pots, with the idea of making them grow fast: it acts on most plants diametrically opposite to what is intended. A pot one or one and a half inches wider and deeper than the one they have been in previously, is sufficient. Healthy plants under five feet will not require shifting oftener than once in two years; from five feet upwards in three or four years, according to the health of the plants. This treatment, in the opinion of some, will appear not sufficient: it will be found enough with a top-dressing every year to keep them in a healthy, flowering condition, the soil being according to our description.

On turning the plant out of the pot, it may easily be observed if the soil has, in any degree, been congenial to it; for if so, the roots will be growing all round the ball; if otherwise, no roots will appear.

Therefore, with a blunt pointed stick, probe away all the bad earth, until you come to the roots; then put the plant in the pot about one inch in diameter, larger than the combined roots, previously putting a few small pieces of broken pots, or clean gravel, to drain off the superabundant moisture, and give light waterings, as the roots in this case will grow but slowly.

Top dress all that requires shifting, probe out the soil down to the roots, and by the side of the pot, taking care not to break the fibres; then fill up with fresh earth, watering gently with a rose on the watering pot to settle it.

OF CLEANING, &c

If any of the plants require cleaning, either by fumigation or otherwise, let it be done before the young foliage appears, according to directions heretofore given. Likewise tie neatly all that require it, clean and top dress those that will not be shifted, having every plant and all in the Green-house, in perfect order, before the throng of spring commences. The weather will now admit, in very fine mornings, of the plants being syringed, which may be done between half past seven and half past eight: and the path or pavement should be washed out once a week, which is a great improvement to the appearance of the whole interior.

In winter whenever any glass is broken it should be immediately mended. Broken glass in cold nights causes a very destructive current of air. It should always be made water tight, for if the drops fall into the pots upon the roots, they will frequently prove fatal to the plants; therefore care ought to be taken during rain to remove those that stand in any manner exposed.

Flower Garden

FEBRUARY

Where the borders and beds were dug in the fall, and compost or a thin coating of well decayed manure given, the advantage will now in part be experienced. If the weather is open about the end of the month, the pruning should be done with the utmost despatch; that all may be prepared for a general dressing next month, and let nothing be delayed which can now properly be accomplished, under the idea that there is time enough.

OF PRUNING, &c

Generally about the end of the month the very severe frosts are over; and when none need be apprehended that would materially injure hardy shrubs, they may freely be pruned of all dead branches, and the points cut off such shoots as have been damaged by the winter. Most of shrubs require nothing more than to be pruned of straggling, irregular, and injured branches, or of suckers that rise round the root, observing that they do not intermingle with each other. Never trim them up in a formal manner. Regular shearing of shrubs and topiary work have been expelled as unworthy of a taste the least improved by reflections on the beauty, simplicity, and grandeur of nature. In fact, the pruning of deciduous hardy shrubs should be done in such a manner as not to be observable when the plants are covered with verdure. It may frequently be observed in Flower-gardens, that roses and shrubs of every description are indiscriminately cut with the shears, the Amórphas and Althèas sharing the same fate.

Robínias, Colùteas, Cyticus, Rhús, Genístas, with several of the Viburnums, and many others, bear their flowers on the wood of last year, and when thus sheared afford no gratification in flowering. And those shrubs that thus flower on the shoots of last year are perhaps worse to keep in regular order, than those to which the knife can be freely applied; but good management while young will ensure handsome free flowering plants.

Climbing shrubs, and others that are trained against outbuildings, walls, or such as are sheltered thereby, and not now in danger of suffering by frost, may be pruned and dressed. These should be neatly trimmed, and the branches moderately thinned out, tying in all the shoots straight and regular. Avoid at all times, if possible, the crossing of any shoots.

There is not a shrub in the garden that agrees so well with close cutting, as the Althèa, and all its varieties. These can be made either bushes or trees, and kept at any desired height. Where the wood of last year is cut to about two or three inches from the wood of the former year, the young shoots of this year will produce the largest and finest flowers, and likewise more profusely. When they have attained the desired height, let them be kept in the most natural and handsome shape that the taste of the operator can suggest. They will bear cutting to any degree.

Honeysuckles of every description may with all freedom be trimmed, providing the frost is not very severe. These are very frequently allowed to become too crowded with wood, and then superficially sheared or cut. The flowers would be much finer, and the bush handsomer, if they were regularly thinned out, divesting them of all naked and superfluous shoots. Of those that remain, shorten the shoots of last year. Where any of the honeysuckle kind has become naked at the bottom, and flowering only at the top of the trellis, or extremities of the shoots, one half of the bush should be cut to within four inches of the ground. It will throw out plenty of fine young wood, which give room for, and train them straight, and to the full extent, during summer. These shoots will flower profusely the following season, and in like manner, when thought proper, the other half can be cut.

Roses of the hardy kinds (termed garden roses) that were not attended to in November, should, if the weather permit, be dressed and pruned forthwith. In small gardens, where these are generally attached to the walls and fences, neatness should be a very particular object. If any of such bushes have got strong and irregular, the most proper method to bring them to order, will be to cut down each alternate shoot of the bush to within a few inches of the surface, thereby renovating it, and, in part, preserving the flowers. Those that are cut down will put out several luxuriant shoots, which must be regularly tacked in, spreading them in a fan shape. These, in another year, will flower well, when the others may go through the same operation. Thus, in two or three years, the bushes will have resumed a different, and more agreeable aspect. By the above treatment, these ornaments of the garden will always have a neat and healthful appearance, and the roses will be much finer. Where they are intended for the borders, they should never be allowed to get too high. In a border from four to six feet, they ought never to exceed four feet at the back of the border, and in front, one foot, after being pruned; they can be kept down by the above method. It is not advisable to cut down rose bushes all at once, unless no regard is paid to flowering. The roses that are in grass plats would have a superior appearance in every respect, if they were kept and trimmed like small trees. They may be of different sizes and heights, according to the extent of the grass plat or clump. A single stem may arise from six inches to six feet, with a head in proportion to the height of the stem. Where it is necessary to have them above two feet, and likewise to carry a good head, inoculation must be resorted to, which, in the months of June and July, will be fully treated of. All under two feet (except the weak growing kinds) will do on their own stems, taking care not to allow shoots to arise from the bottom during the summer. For directions for pruning climbing roses, see March and April.
