What to do if the leaves of cinnabar root turn yellow and fall off

1. Stop watering and loosen the soil

Its leaves begin to turn yellow and fall off usually because the water is not applied according to the growth status, but is applied all at once, resulting in excessive water. Residual water that cannot be absorbed begins to accumulate in the pot, which will damage the roots. The leaves on the plant will also lose moisture, begin to turn yellow and then fall off.

In this case, you need to stop applying water immediately, loosen the soil in the pot, and promote water penetration and drainage. Place it in a ventilated place to promote water evaporation, and wait until the surface of the soil becomes slightly white before watering again.

2. Control the temperature

In the growing environment, if the surrounding temperature is low and the plant cannot withstand it and suffers frost damage, the leaves will turn yellow and fall off.

You can observe the weather conditions and ensure the appropriate temperature. If the temperature drops a lot, you can move it indoors for maintenance, or cover it with plastic film to keep it warm.

3. Spraying pesticides

It can also do this if disturbed by pests. It can be prevented by ventilation and, if necessary, sprayed with pesticides to eliminate it.
