Cuttings are propagated all winter, but end of February, March, April and May is the time best suited. Chrysanthemums root very easily, especially in February, March and April, when the sand is a trifle warmer than the atmosphere. Either sand or coke ashes will do and three inches of it is enough. While there is a little bottom heat and the sun is not powerful a good watering every day is essential. The cuttings will then be rooted in eight or nine days. After first of May the bed will need some cheese-cloth tacked overhead and later a heavy shade on the glass, and to keep the cuttings from wilting a copious watering will be needed two or three times a day. They will take longer to root as the season advances, but will be helped greatly by never letting them wilt from sun or dryness.
The cuttings should be two to three inches long and stout; a few of the lower leaves stripped off and clean cut at the bottom is all that is necessary. Avoid long, weak growths. Hard, woody cuttings should not be used. Moderately soft young growths will root quicker and grow better. Cuttings should be potted off as soon as rooted and not allowed to make long roots; the sooner they come out of the sand after roots appear the less will be their cheek. The cuttings are usually put into 2 or 2 1/2-inch pots, in which, if not too early propagated, they can remain till they go on the bench. Some growers of large quantities transplant from propagating bench to a bench of three or four inches of soil, and there they can be again transplanted to the permanent bench. This saves a good deal of water and you run the risk of neglecting them for water in the month of May. These young plants must have at all times the fullest light and ventilation in abundance. Plants will sometimes need stopping before planting. "When but one flower is needed the strongest shoot can be selected.
If two or three flowers are wanted to each plant then that number of shoots are wanted. This stopping can be done before planting out on the bench if plants are early or still better done after the young plants have started to grow in the benches.
