(1) ground planting. Chimonanthus praecox should be planted in the leeward and sunny places, and the transplanting time is mostly in winter and spring, and the roots of seedlings must be covered with soil. Before planting, apply sufficient manure, manure or decomposed bean cake as base fertilizer in the planting hole. After applying the base fertilizer, cover the fertilizer with a thin layer of soil to separate it, and then put the seedlings into the soil. After planting, water it in time and trim it properly. The management of ground planting Chimonanthus praecox can be extensive. Generally, liquid fertilizer is applied every 20 days from June to September every year (bone meal and cake fertilizer can be soaked in water and then applied after being fully decomposed), which can ensure the good development of branches and leaves and flower buds. Spraying Huazhuangdiling solution in bud stage and flowering stage can promote the bud to be strong, the petals to be enlarged, the colors to be bright, the flowers to be rich and the flowering period to be prolonged. Water once before early winter, fertilize once after flowers wither, and water once. Usually do not water, only when the weather is too dry.

Chimonanthus praecox has strong germination ability and should be pruned in time after flowering. Generally, it is necessary to cut off the part of the flower branch more than 20 cm, shorten the elongation branch of the previous year, and leave 1-2 pairs of buds. The cut hole should be coated with anti-corrosion film to protect the wound and prevent the invasion of germs. In this way, nutrients can be concentrated to pump out new branches, creating favorable conditions for brilliant flowers in the coming year.

(2) potted plants. Potted Chimonanthus praecox should be planted in loose and fertile sandy loam rich in humus. Water the potted plants in time after putting them on, put them under the shade fence for about a month, and then put them in the courtyard or balcony for maintenance. Water should master the principle of thoroughly drying and then watering, not too much water, and the soil in the basin should not be too wet; But you can't do it. If it's too dry, the flowers won't be neat. Usually, topdressing should be done frequently to promote the formation of a large number of flower buds, otherwise flowers will be scarce. Fertilizer must be fully decomposed, otherwise the roots will rot. Dry cake fertilizer should be applied after autumn to meet the demand for nutrients during flowering. After winter, the pot soil should be dry and not fertilized, otherwise the flowering period will be shortened. 65438+ moved indoors in February. If the room temperature is high, it can bloom before New Year's Day; But if the room temperature is low, the flowering period can be postponed until around the Spring Festival. In order to make the petals big, colorful, fragrant and prolong the flowering period, it is necessary to spray Hua Zhuang Di Ling Liquid at bud stage and flowering stage. After flowering, it should be moved to the shade to prevent the premature germination of new shoots and leaves, which will affect the differentiation of flower buds and is not conducive to the next year's flowering.
