At this time, it is necessary to take out Portulaca molokiniensis from the pot soil, cut off the rotten roots in time, and then plant new pot soil and plant it in the new pot soil.
In fact, the nutrient demand of Portulaca molokiniensis is relatively high, but too much fertilization in Portulaca molokiniensis will cause fertilizer damage, which will also make the leaves of Portulaca molokiniensis black, and even cause death. At this time, it can be watered in large quantities to dilute the fertilizer in the soil and reduce the harm of fertilizer.
When Portulaca molokiniensis grows at a temperature lower than 5℃, it is easy to frostbite the plant, and its leaves will gradually turn black. If the plant will be frostbitten for a long time, the frostbitten branches and leaves should be cut off immediately, and the pot should be placed under the sun to keep the temperature under 5℃.
If Portulaca molokiniensis is accidentally harmed by a brown spot in the process of growth, its branches and leaves will show irregular disease spots and gradually turn black, and it is best to shed and wither and die. The blackened leaves should be cut off in time, and then the corresponding insecticide should be sprayed.
If it is found that the leaves of Portulaca molokiniensis start to turn yellow, it may be caused by excessive light, which makes the leaves of Portulaca molokiniensis dewater. It is suggested that the leaves of Portulaca molokiniensis should be transferred to the cool environment, and then moved to astigmatism when the leaves gradually recover, so as to prevent the leaves from being burned again.

Therefore, it is necessary to replace the soil suitable for growth for Portulaca molokiniensis. Peat soil, perlite, pine needles and organic fertilizer can be used to make the basinaceous soil.
The temperature difference between day and night in autumn and winter is quite large, and the environmental temperature is not well controlled at this time, so the leaves of Portulaca molokiniensis will also turn yellow. It is suggested that the leaves should be placed in a sunny environment during the day, and the environmental ventilation should be maintained. At night, the temperature should be properly controlled, and the temperature should not be lower than 5℃ in winter.
During the growth process of Portulaca molokiniensis, it was accidentally harmed by diseases and insects, and the normal growth of Portulaca molokiniensis would be resisted, so as to make the leaves turn yellow.
