DECIDUOUS SHRUBS.
Finish planting all deciduous shrubs in the early part of the month. These plants are generally delayed too long, the leaves in many instances are beginning to expand, thereby giving a check to the ascending sap, which we may safely assert causes the death of one third of the plants, when perhaps the operator or some individual more distantly concerned is blamed.
These shrubs, if properly removed and planted at the exact starting of vegetation, pressing the earth close to their roots when planting, (previously taking care that the small fibres have not become dry by exposure,) will not, by these simple attentions, one out of fifty fail. Those that are late planted should have frequent waterings, and if large, firmly supported, that the wind may have no effect in disturbing the young and tender fibrous roots.
OF PLANTING EVERGREEN SHRUBS.
Now is the season to plant all kinds of evergreen trees and shrubs. In most seasons the middle of the month is the most proper time, the weather then being mild and moist; or if a late season, defer it to the end of the month. When planted earlier, they will remain dormant until this time, and their tender fibrous roots in that case frequently perish from their liability to injury from frost or frosty winds, being more susceptible of such injury than fibres of deciduous plants. They now begin to vegetate, which is the grand criterion for transplanting any plant. The buds begin to swell, the roots to push, and if they can be quickly lifted and replanted, they will hardly receive a check. At all events care must be taken that they are not long out of the ground and exposed to the air, which greatly assists the success in planting. It may be observed that evergreens in general succeed the better the smaller they are, although we have seen plants, trees, and evergreens, successfully lifted upwards of thirteen feet high and fifteen in diameter, and carried several miles. By the second year there was no appearance that such operation had taken place. In preparing a hole for the reception of these plants, make it larger than the roots, breaking the bottom thereof fine, and putting in some fresh soil. Place the plant upright in the centre, putting in the earth and breaking it fine, and give the plant a few gentle shakes. When the roots are more than half covered, put in a pot or pail full of water, allowing it to subside, then cover all the roots, give a second or third pail full, and when subsided the earth will be close to all the roots. Cover with more earth, pressing all firm with the foot. Put more soil loosely on, which will give it a finished appearance, and prevent it from becoming dry, and not requiring mulching, which has an unsightly appearance. All that the wind will have any hurtful effect upon, must be firmly supported, especially large plants. If the weather sets in dry and hot, they should be watered as often as necessity shall direct.
Those that are established, it will be necessary to go over them (if not already done) to cut off all wood killed in winter, and also to thin them if too thick and crowded.
When the above is done, let every part of the shrubbery be dressed off as directed in March. Shrubs of all kinds will now begin to look gay and lively, which may be very much heightened or depreciated, according to the state in which the ground and contiguous walks are kept. Always keep in view that weeds are no objects of beauty.
CARE OF CHOICE BULBS.
Hyacinths of the earliest sorts will begin to expand and show their colours, of which we can boast of a few as fine sorts in the vicinity of Philadelphia, as in any garden of Europe; but even these very superior sorts, when in bloom, are too frequently neglected, being allowed to stand without rods, stakes, or any means of support, likewise equally exposed to drenching rains and scorching suns; and the finest collections may be seen after heavy rains prostrate on the ground, whereas a few hours' trouble would give them the requisite support, thereby preserving their beauty much longer, and giving more gratification. As soon as the stems advance to any height, they should be supported by wires, rods, &c. and tied slightly thereto with threads of matting, or any other substitute, repeat the tying as they advance, avoid tying amongst the florets, because they grow by extension, and are liable to be broken off by so doing. The sun deteriorates the colours very much, especially the red, blue, and yellow sorts; whereas if they were simply protected from the sun by an awning of thin canvass, the colours would be preserved and the beauty protracted. If there are stakes drove into the ground on each side of the beds, about three feet high, with others in the centre about eight feet, having laths or hoops from the side to the centre, formed similar to the roof of a house, so that people may walk or sit under it, the canvass or awning being thin to admit of the light freely, the effect in the time of sunshine from the brilliancy of the colours is peculiarly gratifying. Where an awning is thus erected, it requires to be kept on only from nine to three o'clock in sunshine days, and during nights or time of rain, allowing the awning on the most northern side to come close to the ground when necessary, to shelter them from cold cutting winds.
Tulips in every respect should have the same care and protection, never neglecting to have the beds with a smooth clean surface, and the stems neatly tied up, although they are not in so much danger as Hyacinths.
