Causes and treatments of yellow leaves of cinnabar root

1. Temperature is too low

Reason: The origin of Cinnabar Root is near the subtropics, so it needs to live in an environment with a temperature of 18 to 30 degrees. It is not cold-resistant and cannot be frostbitten. If the temperature is below 8 degrees in winter, it will be frozen and the leaves will turn yellow.

Measures: It is necessary to move it to a warm indoor environment for maintenance in time, and take good insulation measures. The average temperature should be around 15 degrees.

2. Watering problem

Reason: During the growth period, cinnabar root grows very fast, so it requires more water, so more water needs to be applied at this time. If not enough water is provided, yellow leaves are bound to appear. However, if you water too much, yellow leaves may also appear.

Measures: When water is insufficient, add water at least once a day, and spray water around it in summer. When watering too much, you need to stop watering immediately, loosen the soil, and then water it appropriately when the soil surface turns a little white.

3. Insufficient fertilization

Reason: Cinnabar root needs certain fertilizers to provide nutrients for its growth. If the fertilization issue is neglected, it will lack some necessary nutrients. If the growing conditions are not met, the leaves will turn yellow.

Measures: To address the problem of yellow leaves caused by insufficient fertilization, if it is a potted plant, you can add fertilizer while watering. If it is planted in the ground, you can apply fertilizer two to four times in spring and summer, and the situation will improve.
