What are the reasons for yellowing leaves on the black beauty plant?

1. Overwatering

The young leaves at the top of the plant turn pale yellow, the older leaves also gradually yellow, and the new shoots wither. This is caused by prolonged rain or overwatering, which makes the soil in the pot too wet, deprives the soil of oxygen, and rots the roots. You should loosen the soil often, control watering, and avoid heavy rain spraying.

2. Dry soil

The leaves at the top keep a normal color, while the lower leaves gradually dry, yellow, and drop off from the bottom upward. This is caused by the pot soil being too full or by watering that has failed to penetrate for a long time, which makes the lower leaves and branches age. You should water a moderate amount to keep the soil moist.

3. Lack of fertilizer

The plant's leaves are thin and yellow. This is caused by the plant being too large for its pot, or by not repotting or changing the soil for a long time, as well as by insufficient fertilizer. You should gradually increase water and fertilizer and repot at the right time.

4. Fertilizer burn

The plant's leaves become uneven and fail to spread out, the new leaves are thick and fleshy, and the old leaves gradually yellow. You should water frequently, stop fertilizing for a while, and you may scatter a few vegetable seeds in the pot and pull out the seedlings after they sprout, so as to consume the excess fertilizer in the pot and restore the plant to normal growth.

5. Alkalinity

For plants that prefer acidic soil, the leaves gradually yellow because the soil has become alkaline. You can water them with water in which grass has been soaked, and apply a little ferrous sulfate, and the leaves will turn green again. 6. Unsuitable light: Potted flowers are often kept indoors, and their leaves tend to yellow. For sun-loving plants, insufficient light will also cause yellow leaves. For some plants that prefer a cool environment, high temperatures and direct sun will also make the leaves yellow and drop off.

What to do when the Brazilian beauty plant's leaves turn yellow: leaf yellowing care tips

The Brazilian beauty plant is a common indoor foliage plant, but during cultivation, improper care and other reasons may cause its leaves to turn yellow and wither, seriously affecting its ornamental value. So what should you do when the Brazilian beauty plant's leaves turn yellow? Let's take a look below.

What to do when the Brazilian beauty plant's leaves turn yellow

During cultivation, the Brazilian beauty plant may develop yellowing and withering leaves, and there are many causes. Sometimes it is caused by a single reason, but it is often the result of multiple factors, so a correct diagnosis should be made in order to treat the root cause and solve the fundamental problem.

1: Overwatering

Overwatering will keep the Brazilian beauty plant's potting soil wet for a long time, causing a lack of oxygen in the soil, rotting some of its fibrous roots, hindering normal respiration and the absorption of water and nutrients, and causing its leaves to turn yellow and drop off. You should immediately reduce watering, stop fertilizing for a while, and loosen the soil often so that the Brazilian beauty plant's soil is well aerated.

2: Underwatering

The Brazilian beauty plant has relatively high requirements for the moisture level of the surrounding space. If it is watered too little and the surrounding air is also relatively dry, its leaves are likely to become dull and lusterless, wilt and droop, and turn yellow and drop off. Water a small amount and mist it, so that the Brazilian beauty plant gradually recovers and then returns to normal watering.

3: Insufficient fertilizer

The Brazilian beauty plant needs continuous fertilizing. If no nitrogen fertilizer has been applied for a long time, or the pot and soil have not been changed, the soil will lack nitrogen and other nutrient elements, causing the Brazilian beauty plant's branches and leaves to become weak and its leaves to turn yellow. You should promptly replace the soil with fresh, loose, fertile potting soil and gradually apply more dilute, well-rotted liquid fertilizer or compound flower fertilizer.

4: Too much fertilizer

If the Brazilian beauty plant is given too much nitrogen fertilizer, its branches and leaves grow too luxuriantly, and combined with a long period without pruning, the inner branches and leaves of the Brazilian beauty plant do not get enough light, which easily causes its leaves to turn yellow and drop off. You should fertilize the Brazilian beauty plant reasonably and strengthen pruning, so that it has good ventilation and light.

5: Insufficient light

The Brazilian beauty plant likes sunlight. If it is kept for a long time in a shaded place or a spot with insufficient light, its branches and leaves will turn yellow. Simply move the Brazilian beauty plant to a place with ample but not intense light for care.

6: Dry air

If the indoor air is too dry, the Brazilian beauty plant often develops yellowing leaf tips. Use methods such as misting and covering with a plastic film hood to increase air humidity and give the Brazilian beauty plant a growing environment with relatively good humidity.

7: Soil and water on the alkaline side

For potted Brazilian beauty plants, a mix of leaf mold, potting soil, and coarse sand is best. If the chosen soil is unsuitable and lacks soluble iron and other elements that the plant can absorb, its leaves will gradually turn yellow. When planting the Brazilian beauty plant, choose suitable soil, and during the growing period water it often with alum fertilizer water.

What to do when the Brazilian beauty plant withers

When cultivating the Brazilian beauty plant, what should you do if it withers? Slightly pick open the bark to check the necrotic part of the Brazilian beauty plant; normal wood is light green and moist. When you find that the Brazilian beauty plant's wood is dark brown, you can cut off the trunk and keep the section with light green wood for cuttings. If it is all dark brown, then unfortunately there is no saving it, because only trunks of the Brazilian beauty plant whose wood is light green can be rooted by sand cuttings or water cuttings. Note that you should only slightly pick open the bark of the Brazilian beauty plant to check; do not strip all the bark off.

Summary: The above is the information that Tuboshu editor has introduced for you about what to do when the Brazilian beauty plant's leaves turn yellow and what to do when it withers. We hope it can be of some help to everyone.

What to do when the epiphyllum's leaves turn yellow

The epiphyllum is known as the "beauty under the moon." The epiphyllum, also known as qionghua, is an ornamental flower native to Mexico and other places. The epiphyllum's flowers are large and gorgeous, white in color, and fairly strongly fragrant. The epiphyllum has good growth habits, but if it is managed improperly, its leaves easily turn yellow. What to do when the epiphyllum's leaves turn yellow? Today the editor will teach you.

What to do when the epiphyllum's leaves turn yellow?

There are mainly two phenomena when the epiphyllum's leaves turn yellow.

1. Leaf tips scorched and withered.

Scorched and withered leaves generally occur after winter when spring begins, or under the strong sun of summer, or after repotting. Please treat the situations differently according to the circumstances, and do not use medicine or water indiscriminately.

Generally it is mainly caused during overwintering, and strong sun exposure can also cause it, as can the metabolism of old leaves.

The main point is large-scale withering and death. The epiphyllum is very afraid of freezing. After frost damage in winter, the leaves of the whole plant will become soft and then dry up, and it is very hard to save, so flower lovers must pay great attention to winter care and not let all their efforts go to waste. After keeping it warm in winter, when bringing it outdoors the following spring, you must not do so too early. You cannot immediately move an epiphyllum that has just finished wintering into the sun; instead, it should first be placed in indirect light and gradually exposed to sunlight until it is fully placed outdoors. If it is exposed to sunlight immediately, the leaves will turn black and wither. This is very reliable, so I hope you will not try it, since the consequences are irreversible.

If the scorched and withered leaves are due to ordinary care problems, you only need to prune a little; nothing else is needed. When the temperature rises, combined with fertilizing, the plant will quickly recover and turn green again.

2. Damp and poorly ventilated

If the epiphyllum's leaves shrivel, and it is not caused by the soil being too dry, then it is root rot caused by poor ventilation and dampness. So when the leaves shrivel, measures should be taken, because if the plant is relatively large and no measures are taken, by the time it has all shriveled, it will be irreversible. Therefore, when cultivating the epiphyllum, you must pay attention to soil moisture, keeping drainage good, with no standing water, yet not too dry.

The above are some simple protective measures for what to do when the epiphyllum's leaves turn yellow. The epiphyllum is suitable for decorating guest rooms, balconies, living rooms, and so on. It can be cultivated in the southern regions of our country. When the flowering season arrives, the epiphyllum blooms fluttering like a great flurry of snow, a truly spectacular scene. Friends who like the epiphyllum might as well plant one at home; it is both beautiful and elegant.
