Spider Plant Root Rot: What Causes It and What to Do?

Potted flowers and plants are often prone to root rot due to uncontrolled watering, improper fertilizing, and poor management, which can destroy flowers and plants carefully cultivated for years or even decades overnight. It is truly a pity. If an accurate diagnosis can be made in the early and middle stages of root rot and effective measures are taken, some flowers and plants may be saved from death. Below, taking spider plant root rot as an example, we analyze the causes of root rot and the treatment methods.

Spider plant root rot is mainly caused by root damage, waterlogging, or excessive fertilizing. When repotting or dividing, be sure to damage the roots as little as possible, and let them dry in the air for a day before potting. Also control the water volume, and water only when the soil is dry to avoid root rot. Long-term watering plus non-breathable potting soil can also cause this symptom.

For spider plants, it is best to fertilize with light fertilizer frequently. Never apply concentrated fertilizer or undecomposed raw fertilizer, otherwise the roots will easily burn. Now you can take the plant out of the pot, trim off the rotten roots, place it in a cool place to dry for 2-3 days, then plant it in new soil. The new soil only needs to be loose, breathable, fertile, and well-draining.

How to deal with spider plant root rot:

First, dig out the spider plant, cut off the rotten roots, and disinfect with potassium permanganate solution. If there is no potassium permanganate, carbendazim will also work. If you have nothing on hand, clean up the rotten roots thoroughly, then put the plant in a ventilated place to dry. Do not put it in the sun; drying in a cool place is enough. Then replant it in new soil.

As for replanting, because spider plants are very easy to grow, if you have pure sand on hand, you can first grow it in pure sand. According to my testing, spider plants grown in pure sand root quickly.

Treatment tips for the following situations:

1. If the spider plant only has slight root rot, it is very likely due to overwatering and soil that is too wet. At this time, careful care is needed so it can slowly recover. Reduce the amount of water each day. Water once in the morning and once in the evening, then gradually reduce it to watering once a day or once every two days. In this way, the spider plant's soil will not be too wet, and the root rot will gradually improve.

2. When there are signs of root rot in the spider plant, move it out promptly to get some sun, but be careful not to expose it to long periods of strong sunlight. Just let it see the sun and get enough light. About two hours of outdoor sun each day is enough, and the slight root rot symptoms of the spider plant will generally gradually improve.

3. After appropriate watering and sun exposure, if the spider plant's root rot symptoms do not ease, you can appropriately use some plant nutrient solution. Be sure to add it strictly according to the instructions on the bottle. Do not use too much, so as to avoid the opposite effect. It is best to dilute it with clean water in proportion and spray it on the leaves. This is more helpful for the plant to absorb nutrients than adding it to the soil.

4. Usually, a spider plant does not have only one root. If only a few roots of the spider plant have root rot, you can separate the unrotted roots from the rotten roots and repot them in a new pot. This can ensure the spider plant continues to grow. The rotten root parts can be thrown away.

5. If the spider plant's root rot is very serious, the rotten roots must be cut off. Use a sterilized knife to cut off the rotten roots and throw them away, apply rooting agent to the remaining part, then change to new soil. In this way, the spider plant will slowly grow new fleshy roots and thrive again.

6. If the spider plant's roots are completely rotten and there is little hope of regrowth, then carry out transplantation and cultivation promptly. You can use the small plantlets on the spider plant's runners for transplantation. During the growing season, cut off the small plantlets on the runners and plant them in culture soil or water. After the small plantlets grow roots, transplant them into a pot. Then you can successfully cultivate a new spider plant.

Personally, I think keeping spider plants indoors is not as easy as keeping pothos. The most common problem with spider plants is root rot. Spider plant root rot is mainly caused by root damage, waterlogging, or excessive fertilizing. So, how can spider plant root rot be avoided?

When repotting or dividing, be sure to damage the roots as little as possible, and let them dry in the air for a day before potting. Also control the water volume, and water only when the soil is dry to avoid root rot. Long-term watering plus non-breathable potting soil can also cause this symptom. For spider plants, it is best to fertilize with light fertilizer frequently. Never apply concentrated fertilizer or undecomposed raw fertilizer, otherwise the roots will easily burn.
