If the plants in these situations have been properly attended to by admitting air at all favourable times, and when the apartment was below 36° a little fire heat applied to counteract the cold, keeping the heat above that degree; your attention will be rewarded by the healthy appearance of your plants. The weather by this time has generally become milder, so that air may be more freely admitted, especially from ten to three o'clock. Where the leaves are grown to one side, turn the plant with the dark side to the light. They will require a more liberal supply of water, but always avoid keeping them wet. Pick off all decayed leaves, and tie up any straggling shoots; stir up the earth on the top of the pots, breaking it fine where it is hardened by the frequent waterings. This will allow the fresh air to act upon the roots, which is one of the principal assistants in vegetation. For those that require shifting or repotting, see Green-house, March; the plants enumerated there equally apply here, if they are in the collection, with this difference, that well kept rooms are about two weeks earlier than the Green-house. After the end of this month, where there is a convenience, plants will do better in windows that look to the east, in which the direct rays of a hot sun are prevented from falling upon them, and the morning sun is more congenial for plants in this country than the afternoon sun. Where there is any dust on the leaves of any of them, take a sponge and water, and make the whole clean, likewise divest them of all insects. The green-fly is perhaps on the roses; if there are no conveniences for fumigating, wash them off as previously directed. Where there are only a few plants, these pests could be very easily kept off by examining the plants every day. For the scaly insect, see January. If they have not been cleared off, get it done directly; for by the heat of the weather they will increase tenfold.
FLOWERING PLANTS.
Hyacinths, Tulips, Narcissus, Jonquils, and Crocus, will be generally in flower. The former requires plenty of water, and the saucers under the pots should be constantly full until they are done blooming. The others need only be liberally supplied at the surface of the pot. Give them neat green-painted rods to support their flower stems, and keep them all near the light. The spring flowering Oxalis will not open except it is exposed to the full rays of the sun. The LachenÀlia is greatly improved in colour with exposure to the sun, though when in flower its beauties are preserved by keeping it a little in the shade.
PrÍmulas, or Primrose, both Chinese and European, delight in an airy exposure; but the sun destroys the beauty of their flowers by making the colours fade.
CamÉllias. Many of them will be in perfection. See Green-house this month for a description of the finest varieties. Do not let the sun shine upon the blooms. Those that are done flowering, will, in small pots, require to be repotted. The CÁlla or Æthopian water-lily, when in flower, ought to stand in saucers with water.
The Hyacinths that are in glasses must be regularly supplied with water. The roots will be very much reduced by this method; therefore, when the bloom is over, if possible plant them in the garden, or bury them in pots of earth, to ripen and strengthen the bulbs. They will take two years with good encouragement, before they can satisfactorily be again flowered in glasses, and properly they ought not be allowed to bloom next year. Those that are done flowering in pots, can be set aside, and the usual waterings gradually withdrawn. Treat all other Dutch bulbs in a similar manner.
