Let the main branches grow, and leave 2 ~ 3 leaves on the side branches for coring, so as to promote more branches. The last coring shall be carried out 3 ~ 10 days before beginning of autumn. The flowering habit of Xiao Ju is that the top opens first, and then opens downwards in turn. In order to ensure consistent flowering, the lower part is cored first, and then the lower part and the upper part are once every 3-4 days. Because cliff chrysanthemum plants grow up, they need more water and fertilizer, and they should be fully supplied.
