1. Soil alkalization: Daphne odora grows well in acid soil, but if the soil is alkaline, its leaves will gradually turn yellow. You can also test whether the soil is alkaline by yourself, that is, dig out a little soil and add some vinegar. If it bubbles and hisses, it's alkaline.
2. The temperature is too low: its cold resistance is relatively weak, and it usually needs to do a good job of heat preservation during the winter. If the temperature of the breeding environment is relatively low, the leaves will turn yellow after frostbite.
3. Watery rotten root: it belongs to a kind of plant with succulent root. It must not be watered too much. Too long water will cause root rot, which will also cause the phenomenon of yellow leaves.
1. Replace basin soil: if it is caused by soil alkalization, it should be replaced with acid soil as soon as possible. If you don't want to change the soil, you should add a proper amount of ferrous sulfate solution to the basin soil, and the soil will slowly become acidic.
2. Pay attention to heat preservation: if the temperature is too low, it should be placed in a warm room as soon as possible. If the indoor temperature is not very high, you can put a plastic bag on the plant, which can also play a good role in keeping out the cold.
3. Pruning rotten root: after its root system rots, it should be taken out from the old basin as soon as possible, and all rotten root systems should be cut off. It's better to plant it again after disinfection. It's better to slow down for a while.
