1, planted in spring and autumn. When planting on the ground, it should be planted in a semi-cool environment with good drainage. In the southern region, it can be planted in the ground for viewing. Potted plants are suitable for indoor wintering in northern areas. The pot soil should be fertile, loose and breathable sandy loam soil, and the culture soil mixed with humus soil, garden soil and sand can be selected, and it is best to add a proper amount of decomposed cake fertilizer.

2. The suitable temperature for photothermal growth is 1O- 15℃. The growing season should be placed in a sunny place. In summer, it should be shaded or placed under a tree to avoid direct sunlight, and the well should be placed in a windward and cool place.

3. Water and fertilize, and water after planting. After the flowering period from February to April in spring, Daphne odora in Phnom Penh began to sprout and grow new branches and leaves. At this time, it is necessary to keep the basin soil moist. Generally, it should be poured by road, that is, the excess water will flow out from the bottom of the basin immediately, so it is necessary to ensure that the basin soil is loose and well drained. Summer is almost dormant (above 30℃). At this time, watering should follow the principle of "dry but not wet", so that the pot soil is slightly dry and the humidity of the surrounding air increases, which not only reduces the high temperature climate, but also reduces the occurrence of pests and diseases. Autumn is the bud stage, so don't call it flood, otherwise it will easily turn Wu Rui's reproductive growth into vegetative growth, which will affect the next year's flowering. Generally speaking, in this period, according to the principle of "dry thoroughly and thoroughly", in winter, in order to ensure the flowers bloom well in late winter and early spring, water should be replenished in time, but the water temperature should be close to room temperature, usually once a week 1 time or flexibly controlled according to the actual situation. Fertilization combined with watering, base fertilizer should be applied well when potted, and horseshoe-shaped slices at the bottom are better. Avoid applying human excrement and urine, wash thin alum fertilizer water at ordinary times, apply some phosphorus and potassium fertilizer at flowering stage, and mainly apply nitrogen fertilizer after flowering to ensure the needs of nutritional growth. Fertilization is forbidden in summer.

4. Plastic pruning is mainly to prune the branches that affect the plant shape, such as dead branches, weak branches, too dense branches and long branches. , make the plant beautiful and ornamental.
