What to Do If a Wanzhongshan (Cereus fern) Has Root Rot? The Latest Treatment Methods

Wanzhongshan is a fairly common plant, and many children might even mistake it for a cactus. Actually, that is not exactly wrong, since Wanzhongshan is indeed a variety of cactus, and it also shares some of the cactus's characteristics, such as strong vitality and tolerance of drought and poor soil. But even a plant like this can still have problems with root rot. Below, let us look at the causes of root rot in Wanzhongshan and the corresponding solutions.

1. Causes of root rot in Wanzhongshan

1. Watering

Overwatering is the cause of root rot in most plants, and 90 percent of the root rot in Wanzhongshan also comes down to watering, because Wanzhongshan is fairly drought-tolerant, so this plant does not need too much water (you can also think back on the cacti you have grown, and how many of them died from being waterlogged by too much watering). The way to check is very simple: feel whether the soil in the pot is too moist. If it is especially moist, then the root rot is basically caused by overwatering.

2. Light

Wanzhongshan belongs to the cactus genus, and plenty of sunlight and good ventilation are essential conditions for its survival. If overwatering is ruled out as the cause of root rot in Wanzhongshan, then you should consider whether the potted plant has been kept for a long time in a shaded environment where it cannot receive sunlight. To grow Wanzhongshan, you first need to know that it is a plant that likes sunlight and tolerates drought. Once it cannot get light and receives too much water, it will naturally show signs that are unfavorable to its growth.

2. Solutions after root rot in Wanzhongshan

1. “Cut”

The cutting here does not mean cutting Wanzhongshan into pieces and eating them, but cutting off their rotten roots. This point is very important. If the rotten roots are not cut off, the roots of Wanzhongshan will continue to rot. After cutting off the rotten roots, place it in a well-ventilated, bright, indirect-light environment to dry, so that the excess water in the roots evaporates naturally.

2. “Change”

After root rot, Wanzhongshan also needs to have all the soil in the original pot completely replaced. The new soil must be sandy soil with good drainage. Remember, do not water it again. Wait until the plant grows new roots before resuming normal watering care.

3. “Plant”

When planting it again, you can choose to divide it and take cuttings, or you can directly plant the treated plant back. Then observe it carefully for a period of time. Once new roots grow, you can relax. When watering in the future, you must also make sure not to use too much!

The above are the treatment methods for Wanzhongshan after root rot compiled by Qinnongwang for everyone. The causes of root rot in Wanzhongshan are mainly the effects of water and light. After discovering root rot in Wanzhongshan, there is no need to panic. This plant still has fairly strong vitality. As long as it is discovered early, there is still a chance of saving it. You just need to carry out the “three-character motto” introduced above by Qinnongwang!
