Cultivation methods and precautions of Daphne koreana

1. Soil

The best potting soil for Daphne odora is fertile, acidic leaf mold with a high humus content. Alkaline soil must not be used. It can be mixed in a ratio of 5:2: mountain soil (garden soil): leaf mold (pine needle soil) as potting soil.

2. Watering

The roots of Daphne koreana are fleshy, so be careful to water it less often and never too much. If you water too much, the soil in the pot will remain moist for a long time, which can easily cause root rot. After the rain, pour out the accumulated water in the basin in time. After the frost, the water content of the potting soil should be controlled at around 45%.

3. Fertilization

First of all, apply enough base fertilizer in winter. In spring, you should apply 2 to 3 thin layers of cake fertilizer, and make sure it is well decomposed. Stop fertilizing in summer to avoid burning the roots. Apply thin fertilizer frequently in autumn until flowering. After the flower buds form, you can spray the branches and leaves with potassium dihydrogen phosphate. In general, it likes fertilizer more. It is best to apply liquid fertilizer once every 10 days during the growing period. Note that the concentration of the liquid fertilizer should be low. In addition, be careful not to use human feces and urine as fertilizer.

4. Lighting

Daphne prefers a semi-shaded environment and cannot be exposed to the scorching sun. However, the temperature is lower in winter and spring, so it should be placed in a bright environment. In summer, it should be placed in a well-ventilated and shaded place, and sprayed with water appropriately when it is too hot.

5. Notes

1. Pruning

This plant is relatively resistant to pruning, and the denser branches can be pruned off before germination to facilitate ventilation and light transmission. Pruning it after flowering can maintain its beautiful flower shape. You can shorten the branches where the dead flowers are located, and cut off the overgrown branches, crossed branches, overly dense branches, overlapping branches and other branches that affect the beauty of the tree shape.

2. Repotting

Repotting is usually done after the flowers fade, usually every 2-3 years. When repotting, you can remove about 2/3 of the old soil, or you can replace all the old soil with new soil. When repotting, you can cut off some roots that are too long and lift the roots appropriately.
