Daphne's basin soil is the best one with fertile, high humus and acid humus. It must not be alkaline soil. It can be mixed as basin soil according to the ratio of mountain soil (garden soil): humus soil (pine needle soil) = 5:2.
The root of Daphne odora is fleshy, so we should pay attention to less water, and water must not be more. Once too much water is poured, the basin soil will be wet for a long time, which is easy to cause rotten roots. After the rain, the water in the basin should be poured out in time. After frost, the water content of basin soil should be controlled at about 45%.
First of all, the base fertilizer should be fully applied in winter. In spring, we should apply 2-3 thin cake fertilizer water, and pay attention to the rotten one. Stop fertilizing in summer to avoid damaging the root system. In autumn, you should apply thin fertilizer frequently until it blooms. After the bud is formed, the branches and leaves can be sprayed with potassium dihydrogen phosphate. Generally speaking, it prefers fertilizer. It's better to water liquid fertilizer every 10 days during the growth period. Pay attention to the low concentration of liquid fertilizer. In addition, we should pay attention not to use human excrement and urine as its fertilizer
Daphne likes a half shade environment and can't be exposed to the sun. However, the temperature is low in winter and spring, so it should be placed in a light environment. In summer, it should be put in a well - ventilated shade. When it's too hot, you can spray water properly.
This kind of plant is more resistant to pruning. Before germination, the dense branches can be cut off to facilitate ventilation and light transmission. Trim it after the flower to keep a good shape. You can cut short the branches where the flowers are, cut off the extra long branches, Cross branches, over dense branches, overlapping branches and other branches that affect the beauty of the tree.
The change of basin is generally carried out after flower withering, generally every 2-3 years. When changing pots, you can remove about 2 /3 of the old soil, or you can change all the old soil into new soil. When changing pots, you can cut off some long roots, and carry out proper root lifting.
