What causes the leaves of Orange Jessamine to turn yellow and drop?
Orange Jessamine (Murraya paniculata) likes warmth and fears cold. When Orange Jessamine moved indoors for frost protection and warmth in winter develops yellowing and dropping leaves, besides being hit by cold wind and catching a chill, the main cause is that the potting soil is too wet or too dry. It is also related to poor indoor air circulation, a dry environment, or excessive stuffiness.
Prevention methods:
First, the potting soil should not be too wet or too dry; maintaining ordinary moisture is enough.
Second, keep the room temperature at around 6°C, and pay attention to indoor air circulation.
Third, increase the ambient humidity by misting the leaves. After getting through the cold freeze of February, even though some leaves have dropped, if the branches are still green, it will grow new leaves again after being moved outdoors.
