Clivia

The fat and tender leaves of Clivia will turn yellow or even wither if not properly maintained and managed. Some flower lovers will ignore it and allow it to grow. Relevant measures will be taken to correct it, but if the specific root cause is not found and blind treatment will be in vain, then what should we do if the Clivia root is rotten?

Causes and solutions for yellowing of Clivia leaves

1. Temperature

The suitable temperature for the growth of Clivia is 15-25℃. The temperature difference between day and night is most suitable for the growth of Clivia when it is between 8 and 12°C. In summer, when the temperature exceeds 30℃ for a long time, it enters semi-dormancy. If the air humidity is lower than 60% at this time, the leaves of Clivia will turn pale, yellow or even wilted; if the humidity is higher than 90%, the stems and leaves will grow long. In order to prevent these adverse phenomena, measures should be taken to cool down, ventilate and light, and control humidity. When the temperature drops below 8℃ in winter, Clivia basically stops growing. If the temperature drops below 6°C, freezing damage will occur, causing leaf tips and leaf edges to chlorotic and yellow, or even yellow-white necrotic spots.

2. Humidity

Clivia is a plant that likes moisture and has relatively high requirements for the humidity of the growing environment. Its most suitable relative humidity range is 70% to 80%. Clivia in this humidity environment has tender green leaves, clear veins, short, wide and neat leaves, and has high ornamental value. If the pot soil is too dry for a long time and the temperature is high, the leaves will easily turn yellow. However, excessive watering for a long time can easily lead to hypoxia, hinder the normal respiration of the plant, and cause the root system of Clivia to rot or even die. In summer, a small pot of water can be placed at the bottom of the flower pot every 7-10 days to ensure thorough watering. This is called the soaking method.

3. Nutrition

Clivia prefers loose and fertile sandy soil. Soil compaction and insufficient fertilizer supply will cause the leaves to turn yellow and affect flowering. Generally, fertilization can be done in spring and autumn within a year. The rot-resistant leaves must be fermented before use. Without fermentation, the roots will easily burn. Clivia must be replaced with soil once a year. When the temperature of the Clivia maintenance site is above 25℃, it is necessary to lose weight appropriately or stop fertilizing to avoid excessive fertilization and burning the fleshy roots. If the temperature can be lowered to below 20℃, fertilization can still be carried out. Generally speaking, the potting soil should be leaf mold soil, which has better air permeability. Especially when fertilizing in summer, thin fertilizer should be applied frequently and fertilizer water should not drip onto the leaves, so as to prevent the occurrence of spotting disease.

4. Light

Clivia is a semi-positive flower. It likes relatively weak scattered light and is intolerant of strong light. Excessive light can easily cause sunburn. In mild cases, the leaves turn from green to yellow, and in severe cases, the leaves become dehydrated, dry up and die. Short days in winter and spring are more conducive to flowering. Good light is an important condition for ensuring large and colorful Clivia flowers. However, if the place where the light is placed is too dark and there is insufficient light for a long time, the leaves will lose their luster. The old leaves will be dark green, and the new leaves will be thin and yellow or yellow-green (yellow). At this time, the Clivia should be moved to a place with slightly stronger light or supplemented with light. Clivia leaves have phototaxis, so they need to be kept toward the light to maintain the shape of a line when viewed from the side and a fan when viewed from the front.

5. Aeration

The thick fleshy roots of Clivia not only store enough water, but also put forward higher requirements on the soil on which it depends for survival. Only nutritious soil with good air permeability, loose texture and rich humus is suitable for the growth of Clivia's fleshy roots. Clivia placed too densely and the surrounding environment is closed will hinder air circulation and make the plant thin, yellow and thin. Therefore, indoor ventilation should be strengthened to avoid excessive placement density.

6. Root rot

If the Clivia seedlings turn yellow and have yellow spots on the leaves, it may be root rot. You can break the soil to check. If you find a rotten root of Clivia, rinse it with water, put it in a solution of one thousandth of potassium permanganate (to make it lavender), soak it for an hour, take it out, rinse it with water, dry it in the shade, cut off the rotten root area, and Apply plant ash to the cut area, plant it into a new pot, and place it in a ventilated place at 25°C. Do not water too much. New roots will grow in about 30 days.

If the bottom leaves grow new roots from the leaf axils and the leaves turn yellow, this is normal metabolism, so don’t worry too much.

Although Clivia is a well-known flower plant, its leaves are also of high ornamental value, and problems with the leaves will also affect the ability of Clivia to draw arrows. Therefore, when the leaves of Clivia cultivated by flower lovers turn yellow Never turn a blind eye to problems!
