What if the turtle's back leaves are black?

1. The black leaves on the turtle's back may be caused by excessive watering and water accumulation in the soil.

2. Soil water accumulation will hinder root respiration, and black leaves will easily appear after a long time.

3. Clean up the plants in time, clean up the rotten roots, and disinfect the wounds with carbendazim.

It may be that the temperature is too low and the plants are frostbitten.

To move to a warm place, the temperature should be controlled above 5 degrees in winter.

6. In addition, it is also possible that the fertilizer is damaged due to improper fertilization.

7. Rinse the fertilizer with clear water and discharge the fertilizer liquid.
