Avoid exposure to the sun

Clerodendrum thomsoniae prefers a semi-shaded growing environment and is afraid of strong direct sunlight. Therefore, when we are caring for Clerodendrum thomsoniae, we should not expose it to direct sunlight, especially in summer when the light is very strong.

The Clerodendrum thomsoniae likes moisture and needs to maintain sufficient water during the growing period, but be careful not to allow water to accumulate. If too much watering causes water accumulation, the roots of the Clerodendrum thomsoniae will rot, and the leaves will not be supplied with nutrients and will turn yellow. At this time, the accumulated water should be drained out in time, and ventilation should be increased to allow the water to evaporate quickly.

Maintaining Temperature

Clerodendrum thomsoniae likes a warm growing environment. Generally, the temperature suitable for its growth is between 18 and 30 degrees. Its cold resistance is relatively poor. The temperature needs to be kept above 8 degrees in winter. If the temperature is lower than 5 degrees, the leaves of Clerodendrum thomsoniae will be frostbitten and yellow leaves will appear, so good warming measures should be taken in winter.
