What to Do About Root and Stem Rot in Clivia? Detailed Treatment Methods
Clivia has extremely high ornamental value and is a very common potted green plant. Its plant shape is elegant, its leaves are emerald green, and its flowers bloom in orange-yellow, making it extremely beautiful. However, many friends find that before it even blooms, the phenomenon of root rot and stem rot appears. So what should be done about Clivia root rot and stem rot? Let us learn about it together.
1. Causes of root rot
There are three causes of root rot in Clivia. The first is excessive watering. Whether it is a young seedling or a mature Clivia, it must not be overwatered. Once it is overwatered, when the temperature is high and there is also poor ventilation and airflow, root rot is very likely to occur. The second is improper soil. Whether it is leaf mold soil or nutrient soil prepared from horse manure soil and peat soil, it must be fully fermented. If unfermented raw soil is used to grow Clivia, under high temperature conditions, this raw soil will burn the fleshy roots of Clivia because fermentation generates high temperatures. The third is excessive fertilizing. Especially when a large amount of chemical fertilizer is applied, it will irritate the plant and promote leaf growth in the short term, but it causes great damage to the fleshy roots and very easily causes shrinkage and root rot.
2. Treatment methods for root rot
As long as it is not heart rot or stem rot, then it is not very difficult to save. A Clivia with root rot will stop growing and its leaves will begin to turn yellow. At this time, it should be removed from the pot in time, the old soil removed, and after cleaning it thoroughly, soak its root system in water. In this way, you can see which roots have rotted, and then cut off the rotted root parts. After cutting, soak the rhizome in potassium permanganate solution. If you replant it in new soil, it will still rot again, because pathogens remain in the rhizome. Therefore, after soaking with potassium permanganate solution, the pathogens can be killed. Then place it in a cool, ventilated place to dry until half-dry; do not let it dry completely. Then choose a new pot and new soil for planting. The soil is best used after disinfection, and add some decomposed organic fertilizer under the soil, which is beneficial for recovery and growth. After planting, keep it in a shaded, ventilated place to avoid high temperatures, and also be careful not to let the soil become too wet.
3. Causes of stem rot and treatment methods
When spraying water on the leaf surface or fertilizing, if water and fertilizer liquid flow into the gaps at the leaf base, or if the temperature is high or too much base fertilizer is applied, the heat burns and rots the leaf base, and all of these can cause stem rot. If only part of the Clivia leaf base has rotted, you can remove the rotted leaves and then wash it clean. The wound can be dipped in 1000-fold carbendazim solution and then dried, then replanted and managed normally.
