What diseases does Tigerthorn have?

1. Common diseases

For Euphorbia milii, the most common diseases are root rot and stem rot. The symptom of root rot is that the roots will show signs of rot, affecting the transport function. The symptoms of stem rot are that the leaves in the lower part start to turn yellow first, then gradually spread to the upper leaves, yellow spots appear on the leaves, and eventually the entire stem rots, affecting its ornamental value.

2. Causes

The reason for this may be that the soil is not clean. It was not disinfected before filling and contains certain pathogens. Or if there is continuous rainfall and the humidity in the air is high, the Euphorbia milii may be easily infected by bacteria, thus causing diseases. It may also be due to improper watering, which causes water accumulation in the potting soil, leading to rot.

III. Prevention and Control Measures

Prevention is the main focus. During the continuous rainy season, Euphorbia milii needs to be moved to a place where it cannot be exposed to rain to avoid getting wet. If the flowerpot is accidentally exposed to rain, you need to pour out the accumulated water in the pot in time and keep the soil in the pot dry. You also need to spray disinfectants and sterilizers on the plants to completely cure the disease.
