The Garden Under Glass

A GREENHOUSE CALENDAR 311 sufficiently large. They are best started in a box of leaf-soil in a warm atmosphere. Force more flowers and bulbs of all kinds, but introduce them gradually into heat and as they get over let them be hardened gradually until they can be put into a cold house. As the flowers expand introduce them to the conservatory or flowering house. This will give more room in the growing house and enable more plants to be brought forward and a better succession maintained. This refers also to all flowering plants throughout the year. Cut back zonal geraniums as previously advised. Pinch out the points of sweet-peas when they are a few inches high. In the case of those sown in the autumn the leading growth may be taken entirely away as the basal growths will have well thrown out by this time. It is worth a trial to prepare these pieces and put them in a box as cuttings. They root easily in a temperature of 50°. Cyclamen and primulas will now be flowering freely, and will need supplies of liquid manure. If the vine weevil is present it will be making itself known about this time. Flowering bulbs intended for cut flowers should be grouped together in some convenient place where a mat can be thrown over them so that the supply may be kept up for a longer period. Fumigate the house containing calceolarias and cinerarias and pelargoniums, for they are very likely to be infested with green-fly. The stellata type of cineraria will need a stick to support their long stem. Bedding geraniums may have their points taken out to encourage a more bushy habit. The remark applies also to show pelargoniums. Harden sweet-peas and other plants intended for planting outside. Gladiolus—The Bride, Blushing Bride, Peach Bloom and Ne Plus Ultra-—may now be brought from the frames to the greenhouse, also that lovely spiræa, Queen Alexandra. Continue to disbud strepto-
