What to Do if the Rhododendron Roots Rot
This article provides a detailed explanation of what to do if the rhododendron roots rot and shares some small experiences in green plant maintenance for remedying the rotting roots of rhododendron. Let's take a look together.
Alsophila is a common potted plant that prefers shade and drought resistance, and is suitable for growing in fertile and loose soil. It is a relatively easy plant to care for. However, excessive watering can cause the roots of Alsophila to rot. If root rot occurs, the plant should be removed from the pot, pruned, and then repotted.
1. Removing the Plant from the Pot
Take the rhododendron with rotten roots out of the flower pot. Use a spade to circle around the edge of the pot to separate the soil from the pot, making it easier to remove the plant. Tilt the pot and gently remove the plant. Then clean the soil off the roots and rinse the roots with clean water, making sure to remove all the dirt and impurities to expose the roots for pruning.
2. Pruning Roots and Leaves
Use a sterilized pair of scissors to cut off the rotting parts of the roots until clean, white parts are visible. At the same time, cut off some of the branches and leaves because the leaves and branches will turn yellow due to root rot. These leaves and branches should be cut off to ensure that the disease is completely removed to prevent recurrence after repotting.
3. Disinfecting the Wounds
After pruning, there will be a large number of wounds on the plant's roots and branches. To prevent infection, it is necessary to disinfect and kill germs promptly using carbendazim or potassium permanganate. Soak the wounds in a potassium permanganate solution for half an hour or in a carbendazim solution for 10 minutes. After disinfection, place the plant in a shady place to dry.
4. Repotting
Prepare a new pot and soil for repotting. The pot can be a breathable ceramic pot, and the soil should be loose and breathable. Before repotting, apply root-promoting powder to the roots to help the plant grow new roots quickly and adapt to the new pot. Fill half of the pot with new soil, then plant the plant inside, fill the remaining soil, and finally gently compact the soil in the pot.
5. Maintenance
After repotting, water immediately to ensure the soil is thoroughly wet. Do not water for a few days after that, and place the potted plant in a shady place to recover slowly. If the plant lacks water during the acclimatization period, do not water excessively; just spray some water to prevent further root infection and rot. Also, pay attention to the plant's leaves and cut off any yellow or wilted ones to reduce nutrient consumption and the burden on the roots.
