Roots and tillers are clustered, resistant to pruning, strong in germination, flowering first, then leaves, and buds appear on annual branches.

How to cultivate Chimonanthus praecox?

(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. 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, so it should be pruned in time after flowering. Generally, it is necessary to cut off the part of the flower branch above 20 cm, shorten the elongation branch of the previous year, and leave 1-2 pairs of buds. In this way, nutrients can be concentrated to pump out new branches, creating favorable conditions for brilliant flowers in the coming year.

July-August is the flower bud formation period of Chimonanthus praecox. Fertilization can be applied every 15-20 days, and the concentration of fertilizer and water should be dilute, and the ratio of fertilizer and water should be 1: 5. This is helpful for flower bud differentiation. 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.
