The Garden Under Glass

A GREENHOUSE CALENDAR 307 staging. Rhubarb and seakale will also force in a warm shed. Flowers.—Sow Sweet-peas in pots or boxes, East Lothian Stocks, freesias, salvias, streptocarpus, gloxinia, begonia, Primula obconica, verbena, polyanthus, and, later in the month, antirrhinums. Cover the seeds lightly with fine soil, water well, shade from sun and see that no insects, slugs, etc., get at them. Remove the covering as soon as germination takes place. Take- cuttings of Chrysanthemums if sufficient are not rooted, and especially of early-flowering varieties. Take cuttings also of heliotropes, begonias (Lorraine), lobelia, ageratum, verbena, altemanthera, irisine, also of bedding geraniums if sufficient were not rooted in the autumn. Both blue and scarlet salvias may now be rooted from cuttings. Force bulbs of narcissi, tulips, hyacinths. The best policy is to work a few along each week sufficient to meet requirements. Those still in the ashes should be looked over. It is more than probable that they will all need to be taken out by the end of the month. As they pass out of flower they should be set aside where they can be watered until they have sufficiently dried off. Except the Paper-white Narcissi, the Double Roman Narcissi and the Roman hyacinths all may be planted in odd parts of the garden. Lilies of the valley may be brought into heat; also deutzias, azaleas, lilacs, spiræas, dielytras, Solomon’s seal, Hydrangea paniculata and similar forcing subjects. Pot up bedding geraniums from boxes to 3-inch pots. Move heliotropes intended for standards to larger pot and disbud them, using the side growths for cuttings. Pot up gloxinia corms which were shaken out and started in leaf-soil in December into small pots. Shake out corms obtained from leaf cuttings in summer and start in leaf-
