What is the cause of Centella asiatica root rot? How to remedy the root rot of Centella asiatica

Centella asiatica is a common flower plant in life. It is widely used in life because it can treat skin ulcers and promote protein regeneration. However, many people always encounter root rot when growing Centella asiatica. So how to remedy the root rot of Centella asiatica? Let's take a look.

What is the cause of Centella asiatica root rot?

1. Watering too frequently but not enough. This is usually because the watering is too shallow and the water cannot penetrate into the soil. The hair roots of the plants are deep in the soil and cannot absorb water. The water absorption function of the old roots at the top is basically degraded, but they are always soaked in water. After a long time, they will inevitably rot. (Especially for woody flowers)
2. The black rot fungus (Fusarium oxysporum) in the flower soil caused by high temperature and high humidity multiplies rapidly and in large quantities, eroding the roots of the plants and then causing root rot.
3. After the main roots of flowers are bitten by insects, they are not easy to be found because they are buried in the soil (even if the soil is very shallow). If you continue to water them, they will easily rot due to infection.
4. If you water the flowers heavily before they have adapted to the pot after repotting, or if you break the roots in many places when repotting and then water them to cause infection, the roots are likely to rot.

How to remedy the root rot of Centella asiatica

Prune rotten roots

Centella asiatica has a certain degree of moisture resistance, but long-term water accumulation will still cause root rot. At this time, we need to remove the Centella asiatica from the soil, then wash the soil at the roots, and then use sterilized tools to clean all the rotten root parts without any residue. After pruning, soak it in a carbendazim solution for disinfection, and then place it in a cool and ventilated environment to dry the wound.

Repotting

After the root wounds of Centella asiatica have dried, we can re-pot it. It is best to replace the soil with new one when potting, because there are a large number of bacteria remaining in the previous soil, which can easily cause the roots of Centella asiatica to rot again. If we don’t have extra soil around us, we must use the original soil, and then we need to thoroughly disinfect the original soil before using it.

Post-maintenance

During the potting period, we must avoid exposing Centella asiatica to too much light and avoid watering it in large quantities. This is because the roots of Centella asiatica have not yet recovered and its ability to absorb water is relatively poor. If you water it too much, it will easily cause water accumulation, causing the roots of Centella asiatica to rot again. If there is insufficient water in the soil, we can use a spray bottle to wet the soil and wait until new leaves grow before maintaining it normally.

The effects of Centella asiatica on the skin

Centella asiatica has a good antioxidant effect, can treat skin ulcers, promote protein regeneration, and make the skin smoother. For people who often suffer from allergies, using Centella asiatica in moderation can also relieve allergies.

Centella asiatica care methods

1. Soil management: It does not have high requirements for soil, and generally chooses fertile, well-drained sandy soil. If conditions permit, you can also buy soil specifically for growing plants.

2. Water requirement: It has a high demand for water and prefers a humid environment. Timely watering and irrigation are more conducive to the growth needs of Centella asiatica.

3. Light management: Centella asiatica is suitable for growing in semi-shaded places, generally suitable for half-sunlight, not suitable for strong light. When the light is very strong, pay attention to shade it.

4. Nutrient management: Generally, organic fertilizer is used and applied once every 15-20 days. This is more conducive to the root absorbing nutrients and promoting its growth.
