OF PROTECTING PLANTS IN THE GARDEN

During this or next month, according to the state of the season, protect all the plants that are in the ground, which are not completely hardy. To avoid repetition, these will be designated in the general list. The coverings may be straw, Russia mats, canvass, boxes or barrels. The two latter must be perforated in the top, to let the damp air pass off, or the plant would become musty, or finally mortify. Those covered with straw or mats should have small stakes placed round the plants, and covering tied thereto, and remain so until the month of March or first of April. Herbaceous plants that are tender, may be covered with three or four inches of tan, saw-dust, or half decayed leaves, which will tend greatly to preserve their roots. These coverings must be carefully removed on the first opening of spring. The shrubs that are otherwise covered would be greatly benefited by having their roots protected in a similar manner as directed for herbaceous plants.

PROTECTION OF SEEDLING BULBS

If any seeds of Hyacinths, Tulips, Fritillària, were sown in pots or boxes, let them be removed to a dry sheltered situation, and plunged level with the ground; or fill the spaces between them with dry leaves or tanner's bark, and cover the whole with new fallen leaves, laying over all a few boards to prevent the wind blowing them off. These form better coverings than straw or haulm, which is liable to become musty, and communicate the effect to the roots. The above covering is not required until the approach of severe frost.

OF PLANTING DECIDUOUS TREES AND SHRUBS

It is not recommendable to make a general planting of these at this period of the year; the success entirely depending on the nature of the season and the state of the soil. If any are planted, let them be those of the hardiest nature, and in light and absorbent soil, not subject to be stagnated or over-flooded during winter. When this and next month are mild, autumn plantings are frequently as sure as those of the spring. But the precarious state of the seasons is not to be depended upon, therefore avoid largo plantings of any kind, and more especially of delicate roses, the roots of which are apt to rot off except they have been previously grown in pots. Nothing can be more injurious to a plant at this season particularly, than to bed its roots in mortar, by which the tender fibres either perish or are cramped ever afterwards. The soil at time of planting should be so friable as not to adhere to the spade, which is a good rule in planting at any season, or in any soil.

GENERAL OBSERVATIONS

Carry out of the garden all decayed leaves and litter of every description, cutting down any weeds that remain. Collect all the stakes and rods that have been supporting plants; tie them up in bundles for the use of next year, and put them under cover. Look over every part of the garden, and see that nothing has been omitted in the way of covering or other protection. The sashes that are to be used on the frames should be perfectly whole, every interstice in the glass puttied, and all ready for use when occasion may require. Attend to all plants in pots, and give them gentle waterings as they stand in need; but never during the time the soil is frozen about their roots.

Rooms

NOVEMBER

GENERAL OBSERVATIONS

The remarks and instructions that are given last month for these apartments will equally answer here. Where the Dutch bulbs were omitted to be placed in glasses, they ought not to be longer delayed. A few pots of those that were planted in September may be placed in a warmer situation. If they were plunged in the ground, the roots will be strongly fibred, and will produce large flowers, providing the bulbs are of a good sort.

Oxàlis. The autumn flowering species will now be in bloom, and must be kept in the sun to make them expand freely. The neglect of this is the principal reason that these plants do not flower perfectly in Rooms.

Caméllias. These plants, where there is a collection, flower from this period to April; and the general desire to be fully acquainted with the method of their culture has induced us to be liberal in our observations on every point and period through the various stages of their growth and flowering. We will here only remind the enquirer, that a pure air, a damp atmosphere, and giving the plants frequent sprinklings, are the present necessities, which only are conducive to their perfection.

Attend to the turning of Geraniums and other rapid growing plants, that all sides of them may have an equal share of light.

Hot-House

DECEMBER

The uncertainty of the weather in this month requires the operator to be constantly on guard, to ward off danger, either from frost, snow, or cutting winds. The temperature observed last month must be continued, but not exceeded, which would cause premature vegetation, of which the result and effects have already been frequently observed. Always kindle the fires in time, to prevent the heat from being lower than what has been mentioned, lest a severe frost should take, as then a considerable lapse ensues before the fire has any effect, and if the wind blows high, the result might be injurious, unless the house be very close.

OF SHUTTERS

The benefit of these in severe weather is of material service, for the preservation of an even temperature in the house during the night, when changes are not observed, but they ought never to remain on through the day when the fire can be properly attended to. If the front and the lowest sash of the roof are covered with these, it is generally sufficient. They should be made of half inch boards, closely grooved together, having a cross bar in the centre, and one at each end with one at each side, which will make them substantial. If they are frequently painted with care, they will last many years. No snow ought to be allowed to lay on these while they are on the glass, for reasons that we have assigned. See January and February.

Some adopt double panes of glass to supersede the use of shutters, which, they think are attended with considerable labour, (at the most only ten minutes a day while in use.) The sash frame is made a little deeper, so as to allow half an inch between the panes of glass. The one is glazed from the out and the other from the inside. It appears to answer the purpose tolerably well, but the glass must be both fine and even in the surface, lest a lens should be produced, and cause a focus, which would evidently hurt some part of the plants. We are almost confident that we have seen this effect in some instances. There must be a small hole about an eighth of an inch in both ends of each row of glass to allow a current to dry up the moisture that may arise.

OF PLACING BULBS, &c. IN THE HOT-HOUSE

If any Hyacinths or other Dutch roots are wanted to flower early, a few of them may be put in the Hot-house near the front glass, which will greatly tend to forward their time of flowering. By having some brought in every two weeks, a continued succession of bloom will be kept up.

Calceolàrias. Two or three plants of the fine blooming kinds may be placed in this department, towards the end of the month. Divide the roots as soon as they begin to grow, leaving only one stem to each root, which put in a four inch pot, enlarging it as soon as the roots extend to the outside of the ball, that by the month of May they may be in seven or eight inch pots, in which they will flower superbly. Give Alstrœmèrias the same treatment.

GENERAL OBSERVATIONS

If there is a tan bed in the house, and it was renewed in September, the pots should now be plunged therein. The violent heat will partly be over, and the plants are not so liable to suffer at root in this as last month. It will in part prevent the plants from being affected by sudden changes of temperature. Be attentive in keeping all insects completely under. This is the period that these are most neglected, but by attending to the modes of their destruction, as already given, no species of them will either be hurtful or unsightly. Syringe the plants about twice a week, and always remember that decayed leaves or litter of any description do not beautify healthy plants, neither do they form a part of a well kept Hot-house.

Green-House

DECEMBER

The weather may probably be now severe, and it is at all times advisable to keep the temperature as steady and regular as possible. The thermometer should be kept in the centre of the house, and free from the effects of reflection. As noticed last month, sun heat may be as high as 50° in the house, and would not be hurtful, but it should not continue so for any considerable time without admission of air. The fire heat should not exceed 43°, and never be below 33°. It ought not to continue at that point – 36° is the lowest for a continuation that with safety can be practised. So that no error may occur, the temperature ought to be known in the coolest and warmest part of the house, and the variation remembered. Then whatever part of the house the thermometer is placed, a true calculation of the heat of the whole interior can be made. We would recommend to the inexperienced to keep the thermometer in the coldest part of the house. A Green-house compactly and closely built, and the glass all covered with shutters, (which no house ought to be constructed without,) will seldom require artificial heat; but by being long kept close, the damp will increase. In such case give a little fire heat, and admit air to purify the house. In fresh mild weather, give liberal portions of air all over the house; and though there is a little frost, while mild, and the sun shining, the plants will be benefited by a small portion of air for the space of an hour, or even for half of that time.

Whatever state the weather may be through the winter, never keep the house long shut up. Thirty-six hours, or at most sixty, should be the longest time at once; rather give a little fire heat.

We are no advocates for keeping plants long in darkness, and never think that our plants are receiving justice, if kept longer in darkness than two nights and one day.

Respecting watering and other necessary operations, see next month particularly.

BULBOUS ROOTS

Those that were plunged in the garden, if not lifted and brought under cover, should now be done without delay. Clean the pots, and stir up the surface of the soil. Hyacinths grow neatest by being kept very close to the top glass; the flower stems are thereby stronger and shorter. Water moderately until they begin to grow freely.

Flower Garden

DECEMBER

GENERAL OBSERVATIONS

Having in the preceding month, under this head, given details for the protection of plants of a delicate nature, and the forwarding of necessary work, only a few remarks remain to be added. If there is any part therein described omitted, have it done forthwith; every day increases the danger of the effects of frost. If there is a doubt of any plants not standing without protection which are generally considered perfectly hardy, such as Champney, Grevillii, Noisette, and similar roses, tie straw or mats three or four feet up the stems of such, which will prevent all risk.¹⁰ For valuable plants that are on walls, and in danger of being entirely destroyed, it is advisable to be at the expense of having a frame made to answer them, and cover the same with oil-cloth. The frame thus covered could be taken off in mild weather, and replaced again when necessary, causing very little trouble; and if properly taken care of, would last many years. Coverings of any construction and of the same material would answer for any part of the garden, and are the best in our opinion that could be adopted.

Rooms

DECEMBER

As the trying season is now approaching for all plants that are kept in rooms, especially those that are desired to have a flourishing aspect through the winter, a few general instructions (although they may have been previously advanced) will perhaps be desirable to all those who are engaged in this interesting occupation, which forms a luxury through the retired hours of a winter season, and with very little attention many are the beauties of vegetative nature that will be developed to the gratification of every reflecting mind. The following is a routine of every day culture.

Do not at any time admit air (except for a few moments) while the thermometer is below 32° exposed in the shade.

In time of very severe frosts the plants ought to be withdrawn from the window to the centre of the room during night.

Never give water until the soil in the pots is inclining to become dry, except for Hyacinths and other Dutch bulbs that are in a growing state, which must be liberally supplied.

Destroy all insects as soon as they appear; for means of destruction see next month.

Give a little air every favourable opportunity, (that is, when the thermometer is above 33° exposed in the shade,) by putting up the window one, two or three inches, according to the state of the weather.

Clean the foliage with sponge and water frequently to remove all dust, &c. The water thus used must not exceed 96° or blood-heat, but 60° is preferable.

Turn the plants frequently to prevent them growing to one side.

Roses of the daily sort may be obtained early by having them in a warm room, that has a south window, and as soon as they begin to grow, admit air in small portions about noon every day that the sun has any effect. Such must be well supplied with water.

Caméllias, when in bud and flower, should never be allowed to become the least dry, neither confined from fresh air. The effects would be that the buds would become stinted, dry, and drop off. Therefore, to have these in perfection, attend strictly to watering. Give frequent airings, and wash the leaves once in two weeks with water. Never keep them above one day in a room, where there is a strong coal fire, and not above two days where wood is used as fuel. The most of Caméllias will bear 3° of frost without the smallest injury, so that they are easier kept than Geraniums, except when they are in bloom. In that state frost will destroy the flowers. The air of a close cellar is destruction to the buds.

Bulbs in glasses must be supplied with fresh water once a week, in which period they will inhale all the nutritive gas that they derive from that element, if they are in a growing state.

ON THE CONSTRUCTION OF A HOT-HOUSE

There have been many plans devised and visionary projects offered to the public as the best for a well regulated Hot-house. As we intend forming one for practical purposes, we shall adopt a convenient size, have flues for the conveyance of heat, and coal or wood for fuel.

Site and Aspect.– The house should stand on a situation naturally dry, and if possible sheltered from the north west, and clear from all shade on the south, east and west, so that the sun may at all times act effectually upon the house. The standard principle as to aspect is to set the front directly to the south. Any deviation from that point should incline to east.

Dimensions.– The length may be from ten feet upwards; but if beyond thirty feet, the number of fires and flues are multiplied. The medium width is from twelve to sixteen feet. Our directions will apply to the two extreme points, viz. thirty feet by sixteen, and in height at back from twelve to eighteen feet; the height in front six feet, including about three feet in brick basement to support the front glass, which will be two and a half feet, allowing six inches for frame work.

Furnace and Flues.– It is of great importance to have these erected in such a manner as will effectually heat the house. The greatest difficulty is to have the furnace to draw well. As workmen are not generally conversant on the subject, nor yet understand the effect or distribution of heat in these departments, we will give minute details on their construction. The furnace should be outside of the house, either at back or end; the former is preferable, circumstances not always allowing it on the other plan. Dig out the furnace hole, or what is termed stock hole, about five feet deep. Let the door of the furnace be in the back wall of the house, thereby having all the heated building inside, that no heat may be lost. The brick work round the furnace should be from fifteen to eighteen inches thick, laying the inside with fire-brick. The furnace will require to be two and a half feet long, ten inches wide, and one foot high, before the spring of the arch and clear of the bars; leave one foot for an ash pit, then lay the bars. They should be sixteen inches long, one inch broad on the upper side, two inches deep, and two eighths broad on the lower side, and with the door and frame should be cast iron. Half an inch between each bar will be sufficient. The flue should rise from the furnace by a steep declivity of about two feet, and pass the door of the house (without a dip), when it must be elevated above the level of the floor of the house along the front, and at the opposite end of the house must dip to pass the door. The dip must not be lower than the top of the furnace, and should be of a concave form, (avoiding acute angles.) Lead it along the back to enter the wall over the furnace. When thus taken round the house, the heat will be expanded before it passes off, The inside of the flues should be about six inches wide and eight inches deep; plaster the bottom of it, but no other part, as plaster is partially a non-conductor. The above description is for burning anthracite coal, but where wood is to be the fuel, the furnace and flues must be one half larger. We have been particular in the description of furnace bars, as those generally used are miserable substitutes. Circumstances may cause the furnace to be placed at the end or front of the house. In either case the stock hole will not require to be so deep; or where there is only one door in the house a stock hole three and a half feet deep will be enough, which should be built like a cellar to keep out any under water. In all instances pass the first flue to the front of the house, over which have a close shelf eight inches clear, covered with two inches of sand, and by keeping it moist will afford a very congenial heat to young valuable plants. Likewise over the furnace have a frame in the same manner, which will be found valuable. Any part of the furnace or flue that is under the floor of the house, should have a vacuity on both sides to let the heat pass upward.

Bark Pit.– We consider such an erection in the centre of a Hot-house a nuisance, and prefer a stage, which may be constructed according to taste. It should be made of the best Carolina pine, leaving a passage round the whole to cause a free circulation of air. The back and end paths should be about two feet wide, and the front three feet. The angle of the stage should be parallel with the glass, having the steps from six inches to one foot apart.

Where there are some large plants, they may stand on the floor behind the stage, or on tressels, according to their height.

Angle of the glazed roof.– The pitch of the roof is usually varied to agree with the design of the house, and the size of the plants to be grown therein. Where pleasure and ornament are the principal objects, the angle should be about 43°, but a few degrees of inclination either way is of minor importance, the height and elevation being regulated by the size of the plants intended to be cultivated. It is not advisable to shingle any part of the roof on the south aspect.

Materials for glazed frames.– Carolina pine is the best material for the wood work, as it is not so subject to decay from moisture and heat as the other kinds of pine wood. The frames or sashes can be of any convenient length, not exceeding ten feet, and about three and a half or four feet wide, divided so as they can be glazed with glass six inches wide.

Of glazing. The pieces of glass should not exceed six inches by ten, the lappings about one quarter of an inch. The frames ought to have one coat of paint previous to glazing, and all under the glass puttied. Some prefer the lappings to be puttied also. It is our opinion that in a Hot-house these should not be puttied, but in the Green-house the closer they can be made the better.

Of Shutters.– These should be made of half inch white pine, and bound on both ends and sides, having a cross piece in the middle of the same. They ought to be painted once in three years.
