What to do if the leaves of Daphne odora turn yellow

Soil is alkaline

Osmanthus fragrans grows well in loose, fertile, humus-rich soil. If the soil chosen is highly alkaline, the leaves of Osmanthus fragrans will gradually turn yellow.

Solution: Replace the acidic soil, or add ferrous sulfate solution to the potting soil. (Smart editor, here is a complete set of soil acidification methods for you, please take a look! →_→ Soil acidification methods )

Too much sunlight

Osmanthus fragrans likes sunlight, but is afraid of high temperatures and scorching sun. In summer, the plant should be placed in a cool and ventilated environment, or an environment without direct sunlight. Too much sunlight or no sunlight will cause the leaves to turn yellow.

Solution: Place the Osmanthus fragrans in a place with sufficient scattered light.

Temperature is too low

The drought resistance of Osmanthus fragrans is poor. If the temperature is too low, the growth of the plant will be inhibited and the leaves will easily turn yellow and fall off.

Solution: The potted Osmanthus fragrans should be moved indoors before the Descent of Frost, and the temperature should not be controlled below 5℃.

Excessive water

Osmanthus fragrans prefers shade and is afraid of waterlogging, so the amount of watering should be controlled when maintaining it in a pot. When the soil in the pot is too wet, root rot and stem rot are prone to occur, causing the leaves to turn yellow.

Solution: Replant with clean and sterilized culture soil, place in a cool and ventilated place, and water appropriately.

Improper fertilization

Osmanthus fragrans likes fertilizer, especially well-rotted organic fertilizer, but the amount should be good and fertilization should be done frequently. If too much fertilizer is applied and water is not applied in time, it will easily cause fertilizer damage, causing the leaves of the Osmanthus fragrans to turn yellow.

Solution: Apply fertilizer reasonably, choose decomposed bean cake fertilizer water, and dilute it before applying fertilizer.

Pests and diseases

If Osmanthus fragrans is not properly cared for, it is easily attacked by diseases and pests, such as wilt or leaf spot, and the leaves will turn yellow and dry.

Solution: During the disease period, spray the pesticide in time, once a week, and spray or irrigate the roots continuously for 5 to 6 times, the effect will be more obvious.
