What to Do When Phalaenopsis Roots Rot? A Detailed Guide to Prevention and Control
Phalaenopsis is an epiphytic orchid of the Orchidaceae family, with very high ornamental value, and it is also very popular in our country. When growing orchids, if management is improper, many problems often arise. One of the more common ones is root rot, which can seriously affect the growth of Phalaenopsis and even lead to death. So what should be done about Phalaenopsis root rot? Let us take a look below!
1. Root trimming
When root rot is found in Phalaenopsis, be sure to promptly remove the entire Phalaenopsis plant. Then clean the soil from around the roots of the Phalaenopsis plant thoroughly, exposing the complete root mass. Next, prepare sterilized scissors, observe the roots of the Phalaenopsis, and use the scissors to cut off the roots of the Phalaenopsis plant that have already rotted. When cutting the roots, be sure to observe carefully and do not miss cutting a single rotten root. Do not be soft-hearted either; however many roots have rotted, that is how many should be cut, otherwise it will affect the effectiveness of root trimming and will also hinder the recovery of the Phalaenopsis plant's growth capacity.
2. Disinfection
After the roots have been trimmed, the plant cannot be put back into the soil immediately. We also need to use agents such as potassium permanganate to disinfect the roots of the plant. If disinfection is not done, the cut root wounds of the Phalaenopsis are prone to bacterial infection, which will worsen the condition and, in severe cases, cause death. After disinfecting the roots, place it in a clean, ventilated and shady place to air-dry. Then replace the old soil previously used for planting with new soil, and disinfect the flower pot as well. Because old flower pots contain many bacteria, repotting in them may still cause root rot in Phalaenopsis.
3. Repotting
After the Phalaenopsis has gone through a series of treatments such as root trimming and disinfection, it can be repotted. When repotting, be careful to avoid the roots of the Phalaenopsis being injured again, which would affect functional recovery. After repotting, be sure to cover the roots of the Phalaenopsis well with new soil and avoid leaving them exposed. After repotting, do the care work well: the leaves of the plant must not be exposed to direct sunlight, and the roots must not come into direct contact with fertilizer, etc. After repotting, place the Phalaenopsis in a shady place with good air permeability for care, and only carry out normal cultivation after its growth capacity has recovered.
4. Prevention methods
Although timely remedial measures after Phalaenopsis root rot can recover a certain amount of loss, it will still affect the benefits of cultivation to some extent. Therefore, we should focus on prevention. When watering, be sure to control the amount of water well. Do not water too much, to prevent water accumulation in the soil from causing the roots to rot. Similarly, do not fertilize excessively, to avoid too much fertilizer causing root burn. The soil should maintain good air permeability, and regular disinfection should be carried out to avoid infection by pathogens, etc. Do the basic management work such as rain protection and light protection well. Create a good growing environment for Phalaenopsis.
