The Garden Under Glass

94 THE GARDEN UNDER GLASS cuttings root more readily in the autumn and make finer plants than spring cuttings. A few toppings of thegrowths will induce a more bushy appearance. Cold frame and outside treatment will serve as with zonals. They are grown on precisely the same lines. Show Pelargoniums These are now becomingonce more populär, though why they should for a time have been otherwise I cannot imagine. I strongly advocate the growing of young plants each year, so that some of the older ones may be discarded. Besides giving a more dignified appearance in the foliage, they flower boldly, though for making large masses of bloom the young must undoubtedly give place to the older and consequently larger plants. Strong, healthy cuttings may be got at the beginning of July when the plants have finished flowering and are cut back. I prefer to put them into a box (where they are more likely to be kept in a right condition of moisture), in a frame or cool greenhouse. It will be some time before they are rooted, but when they are it is best to transfer them to small pots two and a half inches in diameter and set them in a cool greenhouse. Here they will have a chance to get well rooted, ready for moving into 4-inch pots, in which they may remain until the beginning of the year. By this time they will be getting pot-bound and may be removed into their flowering size-—6-inch pots. I have got them along to flower in 7-inch pots within the year, but it requires good treatment throughout. Throughout their career pelargoniums need cool con-ditions and plenty of light. To shade them will induce thin, weak growtli and encourage green and wliite fly, to
