Vines.—Attend to last week’s instructions as to stopping all laterals, &c., and thinning the bunches in good time; and tie up all the principal shoulders with soft strands of matting. Never allow the head or hand to touch the berries. Give them plenty of air-moisture during their swelling season; to be discontinued when they begin to colour. Shy-setting sorts—such as the Black Damascus, Cannon Hall Muscat, &c.—will set better by thinning the blossom-buds before expansion, by which a more regular and compact bunch will be produced. Late Vines should be pruned and dressed; and if not frosty the lights to be removed, which will retard their breaking, and benefit the trees.
FOURTH WEEK.
GREENHOUSE AND CONSERVATORY.
During continued frosty weather fires must be kept up in these houses, and then particular attention must be given to the New Holland plants, Heaths, and such like, which are impatient of heat, that they do not suffer from want of water. Be sure that the ball is thoroughly moistened at least once a-week.
PITS AND FRAMES.
Amongst climbers, Calampelises, Cobœas, Lophospermums, Maurandyas, Rodochitons, and Tropæolums, deserve attention at this time, increasing them by cuttings or by seeds. Some annuals are also worthy of attention, such as Brachycomas, Phloxes, Portulaccas, Schizanthuses, with others which may all be forwarded in heat. Whoever has not yet attended to the propagation of plants for bedding out, should now begin, without further delay, to put in cuttings of Fuchsias, Verbenas, Heliotropes, Petunias, Salvias, Scarlet Geraniums, &c., to have good plants in May and June. All straggling and weak shoots to be topped back to form robust, bushy plants.
STOVE AND ORCHID-HOUSE.
Some of the stove plants that have done blooming should be cut back, such as the Eranthemum pulchellum, Euphorbia jacquiniæflora, Geissomeria longiflora, Gesnera lateritia, Justicias, Linum trigynum, Poinsettia pulcherrima, and others. A bottom heat will be necessary when they are repotted, which may be done in about three weeks or a month. Such of the most forward plants, as they require shifting, to be attended to. The condition or fitness for this must, in a great measure, be determined by the progress the shoots and roots have made.
FORCING-PIT.
Continue to introduce plants of Azaleas, Hyacinths, Heliotropes, Hydrangeas, Kalmias, Sedums, Lilacs, Narcissus, Pelargoniums, Pinks, Rhododendrons, and Roses
