How to deal with root rot in sago palm? Practical solutions shared
The sago palm, a landscape plant also known as the "cycad," is famous for its slender, hard yet distinctive leaves. Not only that, the sago palm is a very ancient plant with a sturdy bulbous trunk; even small seedlings or young plants have plenty of character. Although it is as hard and resolute as iron, its root system consists of milky-white fleshy fibrous roots, though these fibrous roots are usually numerous and grow rather thick and sturdy.
Precisely because its roots are fleshy roots, it is very sensitive to water, with a characteristic of being drought-tolerant but not water-tolerant; overwatering easily suppresses root respiration, leading to root rot. It is quite common for sago palms to suffer root rot due to improper care and management, especially improper watering management. However, once root rot occurs in a sago palm, we need to rescue it promptly, otherwise it may bring serious consequences. So, how do you deal with root rot in a sago palm? Below, the editor shares some solutions.
When a sago palm develops root rot, the plant not only stops growing, but the old leaves also turn yellow and die, and the new leaves generally become wilted and droopy, until the plant dies. Before the plant is beyond saving, we should promptly remove it from its original pot, then shake off the soil clinging to the roots, find the rotten roots and cut off the decayed parts. Then apply some sulfur powder or plant ash to the wounds left after root pruning to prevent bacterial infection from causing further rotting.
After dealing with the root problem as described above, we also need to place the plant in a well-ventilated, semi-shaded spot to air-dry the wounds until they congeal, dry, or heal before repotting it. If we repot directly without drying the roots, the wounds on the fleshy roots will easily become infected when watered, causing the roots to continue rotting from the wound sites. Therefore, drying the roots is a very necessary and essential step.
After the wounds on the sago palm's roots have dried, we repot it into a flower pot, and it is recommended to use a new pot and new soil for replanting. Because the original pot may carry quite a lot of bacteria from the previous root rot, for safety's sake, it is recommended to choose a larger pot and use new soil to plant it slightly deeper, since its root system is very well developed, numerous and long, and consists of fleshy fibrous roots that are relatively easily damaged.
It is recommended to plant it in fertile, loose, sandy soil with strong air permeability and drainage. After potting, water it thoroughly once as a settling-in watering. Then place the pot in a well-ventilated spot with plenty of scattered light to let it recover. One detail to note is that if the plant has quite a lot of leaves, it is recommended to cut off most of the old leaves and keep only a small number of new leaves, which can reduce water consumption and evaporation, making it easier for the plant to establish and survive.
When caring for the repotted sago palm in a well-ventilated environment with plenty of scattered light, be sure to do a good job of maintaining humidity, especially when the light is relatively strong and the temperature is relatively high; you can frequently spray some water on the leaves, combining this with watering at the roots. If nothing goes wrong, usually after 2-3 months the repotted sago palm will successfully take root, and the plant will return to normal growth, so our care and management work should also gradually return to normal.
