What to do if the leaves of Clivia Miniata rot
In comparison with the cultivation content of Clivia Miniata in most people's flower clinics, how to deal with the rotting leaves of Clivia Miniata is explained comprehensively below.
Some flower enthusiasts may find that the leaves of their Clivia Miniata are rotting and not know what to do. Don't rush, first find out what caused the leaves to rot, then you can treat the symptoms accordingly. If you deal with it blindly, it will not fundamentally solve the problem of rotting leaves.
Here are several situations that can cause the leaves of Clivia Miniata to rot.
1. Clivia Miniata exposed to strong sunlight for a long time not only makes the leaves rough and lose their green color but can also easily cause "sunburn disease," making the leaves suddenly turn yellow and dry. In severe cases, the entire leaf turns yellow. Therefore, shade the plant for two to three hours around noon in summer. Once the leaves have turned yellow, cut off the leaves and encourage new growth.
2. Over-fertilization or over-watering, poor leaf hygiene, or mold infection can lead to rotting leaves. The leaves may rot from the base, the center, or the outside. In severe cases, the leaves can rot completely in about five to six days. Promptly control water and fertilize appropriately to keep the soil moist. Cut off the rotting part immediately and sprinkle oxytetracycline powder around the affected area for thorough disinfection, then place it in a well-ventilated and sunny area.
3. When the temperature rises above 25°C, the growth of Clivia Miniata is inhibited. If fertilization continues, the leaves will become weak and spindly, leading to an unhealthy plant, or even rotting roots and stems. Excessive fertilization can cause newly grown leaves to suddenly curl. Re-plant in fresh soil or water thoroughly several times to wash away or dilute the concentrated fertilizer.
4. High humidity during the plum rain season, poor ventilation, and hot temperatures can cause the leaf tips to wither, weakening resistance to diseases. Use 0.1% carbendazim or thiophanate-methyl for alternating sprays every 10 days.
5. Over-watering can cause root rot, leading to leaves yellowing and falling off from the bottom up. Dig up the plant, remove the soil, cut off the rotting roots, and let it dry for four to five days to slightly shrink the roots before re-potting. If only half of the plant is watered, the roots will become shriveled, and the leaves will also turn yellow and fall off from the bottom up. Water thoroughly in time.
6. Clivia Miniata has fleshy roots with较弱 water absorption capacity, and the leaves are thick and contain a lot of water. If the soil is too wet or too dry for a long time, it can cause reverse water flow, leading to blackening and rotting of the leaf tips. Keeping the soil slightly dry is recommended. It's also important to note that for small, medium, and large plants, pouring water on the central leaves, frequent rain, or water seeping into the center can cause the new leaves in the center to rot, and in severe cases, the heart can rot. Therefore, when watering Clivia Miniata, do not pour water on the leaves, especially not into the central leaves.
7. High temperatures, intense sunlight, low rainfall, dry environment, poor ventilation, poor drainage, or the use of fresh fertilizer can cause the leaves to turn yellow or fall off. Use loose, slightly dry soil, apply well-rotted light fertilizer, and place it in a ventilated and cool environment.
8. Unfermented manure or meat bones used as a base in the pot can easily cause white threadworms, leading to leaf yellowing. Change the potting soil and re-plant.
9. If there are leather-like yellow spots in the center of the leaves, it appears to be a leaf disease on the surface, but it is actually a problem with the roots. For example, overly wet soil, a stuffy and poorly ventilated placement, or the application of fresh or concentrated fertilizer can cause these symptoms. If there is too much or too concentrated fertilizer, change the soil immediately. If the placement is incorrect, change the location to keep the soil slightly dry.
10. Fungal activity in the potting soil can cause leaf spots. Use formalin for timely disinfection. If leaf spots have appeared, apply a 1000-fold solution of oxytetracycline or tobacco stem water to the affected area to control the spread of the spots.
The above are some tips on what to do if the leaves of Clivia Miniata rot. I hope this article can be of some help to you!
