What to use to disinfect sago palm root rot? Introduction to the correct treatment method
The sago palm not only has a thick trunk at its rhizome, but also a very developed root system. Generally, we need to prepare a large flower pot to grow it. However, the sago palm is relatively drought-tolerant and afraid of waterlogging, so overwatering easily causes root rot. When root rot occurs, we must take remedial measures in time. Usually, the plant is taken out of its original pot, then the roots are trimmed and sterilized, and after the roots are dried, it is planted into a new pot with new soil.
After trimming the roots of the sago palm, the wounds on the roots must be treated, otherwise infection of the wounds easily occurs after direct contact with water, making the root rot worse and worse. Generally, we need to sterilize and disinfect the wounds to avoid infection, because after potting, it is usually necessary to water with settling water to ensure survival. So, what should be used to disinfect sago palm root rot?
The root system of the sago palm is very developed. After taking it out of the pot and removing the old soil around the roots, we can see a large mass of roots. This is also why, when growing it in a pot, we need to use a large, deep pot, mainly to give its root system sufficient space to spread and extend. Moreover, on closer inspection, the normal roots of the sago palm are milky white, poorly growing or diseased roots are yellow, and rotten and decayed roots are often black.
Therefore, when trimming the roots after sago palm root rot, the original healthy milky white roots should be kept as much as possible, and the other poor roots, especially the black rotten roots, should be cut off, and only then can they be sterilized and disinfected. The sterilizing and disinfecting agents commonly used after root damage in many flowers and plants are usually carbendazim or potassium permanganate solution. And because the root system of the sago palm usually grows numerous, thick and strong, and especially long.
In this case, if carbendazim or potassium permanganate solution diluted with water is used to soak the roots, the amount used is often very large. From the perspective of economy and practicality, it is generally recommended to use plant ash for sterilization. We can apply plant ash directly to the wounds on the root system, applying a layer of plant ash to cover the wounds. Then put it aside to dry for a period of time, and after the wounds coagulate, dry or heal, repot it with plain sand, water it with settling water, and let it recover.
