What to Do When Bleeding Heart Vine Leaves Turn Yellow? The Correct Way to Handle It Is Here

What to do when Bleeding Heart Vine leaves turn yellow: in summer, the sunlight is fairly intense, and exposure to the sun is one of the causes of yellowing leaves in Bleeding Heart Vine; in winter, the sunlight is not as intense, but the daylight hours are short, and a lack of light also easily causes leaves to turn yellow. Bleeding Heart Vine (Clerodendrum thomsoniae) prefers a warm, humid, semi-shaded environment with plenty of sunlight, and is not cold-tolerant. The overwintering temperature should be above 15°C; being below 10°C for a long time can cause leaf drop and even death. It is propagated by sowing or cuttings; the seeds have a short lifespan, so sow them immediately after collection.

The suitable growth temperature for Bleeding Heart Vine is 18-24°C, from February to October it is 18-30°C, and from October to February of the following year it is 13-16°C. In winter, the temperature should not be lower than 8°C; above 5°C the stems and leaves are prone to frost damage, with mild cases causing leaf drop and severe cases withering the tender stems. During the vegetative growth period, the temperature can be relatively high; at high temperatures above 30°C, as long as water is supplied adequately, it can still grow normally. For reproductive growth, that is, the flowering period, the temperature should be relatively lower, around 17°C.
