Clivia Miniata care knowledge: How to deal with the yellowing of the lowest leaves of Clivia Miniata and the green plant flower knowledge of Clivia Miniata beginner maintenance techniques, let's take a look together!
Why do the lowest leaves of Clivia Miniata turn yellow after a period of time? — Clivia Miniata is a flower with strong adaptability. First of all, it is not as picky about the planting materials as orchids, it can be planted with pure decomposed leaf soil, or with ordinary garden soil mixed with some river sand or organic matter. However, any soil used must be strictly disinfected at high temperature to kill parasites and bacteria in the soil.
Clivia Miniata also has strong drought resistance and does not need to be watered too frequently. The supply of fertilizer and light is the same as that of other ordinary flowers, generally scattered light and dilute nitrogen, phosphorus, and potassium all-element fertilizers. The temperature requirement is generally between 5 to 35 degrees, and it can grow normally in a well-lit ordinary indoor environment. However, many flower friends always find that their Clivia Miniata either has incomplete leaves or wilted leaves, and the plant lacks vitality. So, what is the reason for the yellowing of the lower leaves of the Clivia Miniata plant after a period of time? This mainly needs to be considered from three aspects.
First, excessive watering or too frequent watering. Clivia Miniata plants have succulent roots, storing a large amount of water and nutrients inside. Therefore, Clivia Miniata plants have strong drought resistance and tolerance to poor soil. If you continuously water the plant for no reason, the soil in the pot will be in a wet or waterlogged state for a long time. This will cause a serious lack of oxygen in the soil, and over time, it can easily lead to difficulty in root respiration and rot. After the original roots rot, due to the constant moisture in the soil, it is difficult to grow new roots. Therefore, the plant cannot absorb water and nutrients and can only consume the water and nutrients in the plant body. Over time, the old leaves at the bottom begin to yellow and wither. Even if the yellowed leaves are removed, if the soil remains in a wet state, the plant will still find it difficult to grow new roots, but the leaf heart and other leaves will continue to consume water and nutrients, so they will continue to turn yellow and wither upwards.

Second, the plant is too dry. Although Clivia Miniata has strong drought resistance, if it is not watered for a long time, the roots will absorb no water and gradually shrink and become dry. The upper part of the pot will also be unable to absorb water and nutrients like the rotten roots, leading to the same situation where only the water and nutrients in the plant body are consumed. Over time, the yellowing of the old leaves occurs.
Third, slight fertilizer damage. Many friends, when fertilizing the plant, are always afraid of starving the Clivia Miniata or just want to save trouble, and apply a large amount of fertilizer at once. Especially unripe organic fertilizers or excessive chemical fertilizers, an excessive application of these fertilizers can cause a large number of roots to burn and rot. In more severe cases, it can even cause the entire plant to rot. Slight fertilizer damage will only cause the succulent roots of Clivia Miniata to rot. After the plant roots rot, the same two situations mentioned earlier will occur, and over time, the old leaves at the bottom of the plant will slowly wither.
In this case, you should first review your management and operation methods, turn the pot over to find the cause, remove the rotting roots according to the actual situation of the operation, soak the root disk in a 1000-fold solution of fungicide or potassium permanganate for one hour, then wrap the leaves with a wet towel to dry the root disk. Replace the nutrient soil if necessary (both too wet soil and over-fertilized soil should be replaced), and for soil that is yellow due to lack of water, you can replace half or not at all, then replant it in the pot. Water thoroughly and place it in a well-ventilated semi-shaded area, maintaining a temperature of 20 to 28 degrees. After one month of care, new roots will grow again.
