The invention discloses a special fertilizer for flowers. The special fertilizer comprises mineral nutrients, clay fine powder and a cellulose derivative, and also can comprise alginate and a chitosanderivative. In one technical scheme of the special fertilizer for flowers, the cellulose derivative and the clay are subjected to a cross-linking reaction, so that the release speed of the fertilizeris reduced. In one technical scheme of the special fertilizer for the flowers, alginic acid and the cellulose derivative are used, so that the physical structure of soil can be improved, soil hardening is reduced, the nutrient leaching loss quantity is reduced under the combined action, and the utilization efficiency of the fertilizer is improved. In one technical scheme of the special fertilizerfor the flowers, the chitosan derivative and the alginate are used, so that the disease resistance of the flowers can be improved, the use quantity of highly toxic pesticides is reduced, and the special fertilizer is more envi
