ZINNIA

Zinnia elegans. Half-hardy annual THE double varieties of Zinnia have entirely eclipsed the single form of this flower. They grow to an immense size and are extremely valuable for beds and borders, the plants remaining in bloom for a considerable period. Double Zinnias are



so varied in colour and beautiful in form that they deserve to take high rank as exhibition flowers. The Zinnia is delicate, and should not be sown too soon. March is quite early enough to commence operations, and the first week in April will be none too late for sowing. A compost that suits Asters will answer admirably for Zinnias. Sow in 4-1/2 inch pots, which should have very free drainage, and cover the seed thinly with fine soil. Plunge the pots at once in a temperature of about 60 deg., when the seed will germinate quickly, and the plants on attaining one inch in height can be potted off separately. Place them in a close frame, shade from sunshine, and when well established, gradually give air and harden off. It will not be safe to transfer to the open until the first week in June, unless the position is exceptionally sheltered and the soil very dry. A shrubbery border is a suitable spot, and the more scorching the season the finer will be the flowers. There must, however, be shelter from the wind, for the stems of Zinnias are hollow, and easily damaged by a storm. A satisfactory display of this flower may be obtained without the aid of heat by sowing in the open ground about the middle of May. Select a sunny sloping border or bed for sowing, enrich the soil, and make it fine. Press this down rather firmly, then drop three or four seeds at intervals of from fifteen to eighteen inches between each group, and lightly cover them. In due time thin to one plant at each station. If they thrive the branches will not only meet but overlap, and produce a grand display. In the event of very dry weather at sowing time the ground may be watered before the seed is put in, and then be covered with dry fine soil. Zinnias do not transplant well, except as small seedlings. When it is necessary to undertake the task, choose, if possible, a showery day, and shade each plant with an inverted flower-pot for a few days, but take off the pots in the evening. Zinnias intended for exhibition must be treated in a more generous fashion than plants that are grown for border decoration, or for the sake of yielding cut flowers. The seed may be raised in heat as already directed, but the border will need to be prepared with special care and liberality. Should the soil be heavy, it must be reduced to a friable state during winter. Before the plants are put in, raise the land into ridges about four or five inches high. Plant on the top of the ridge, and then an application of soot or lime (not too near to inflict injury) may be used as a precaution against slugs. In a wet season the plants will stand a better chance than if put on the flat, and if a scorching summer comes they will be none the worse for it. As the flowering time approaches mulch the ground with well-decayed manure. The plants must be carefully staked and tied out. It is not merely necessary to secure the main stem, but the branches should also be supported, or when weighted with flowers they will be very liable to give way under a moderate wind. Superfluous branches may be removed, but not so severely as to start new growth to the detriment of the flowers. Disbudding also will have to be practised for the highest class of flowers. Only one bloom should be allowed to develop on each branch at a time, and this must be protected from sun and rain after it is about half grown.
