Reasons for Yellowing Leaves and Yellow Spots on Pothos and How to Fix Them

Because pothos is relatively easy to grow and can also purify the air, many people grow pothos indoors. However, quite a few people have discovered yellowing leaves on their pothos during the growing process. So why do pothos leaves turn yellow, and are there simple solutions for yellow spots on pothos?

I. Main Reasons for Yellowing Pothos Leaves

Overall, when pothos leaves turn yellow, if it is grown in water, it is mostly due to bacteria in the water; if it is grown in soil, it may be root rot. Relatively speaking, water-cultured pothos is more likely to develop yellow leaves than soil-cultured pothos. The specific factors causing yellowing pothos leaves mainly include three aspects: improper watering, imbalanced lighting, and incorrect fertilizing. Below is a detailed analysis of the three major factors that cause yellowing pothos leaves.

1. Improper watering: Both overwatering and underwatering can cause water-induced yellowing in pothos. If the leaf surface appears dull yellow and lusterless, and new tips shrivel and stop growing, it may be overwatering. If the leaf tips or edges become withered and dry, new leaves grow normally, but old leaves turn yellow and drop, it is underwatering. Yellow leaves should be removed promptly once discovered.

2. Sunlight: Pothos prefers shade. Strong light exposure will cause the leaf tips and leaf margins to wither, and yellow spots will appear on the sun-facing parts of the leaves. On the contrary, if placed in a dark environment for a long time, the leaves cannot receive enough sunlight and cannot form chlorophyll, which will also cause pothos leaves to turn yellow. Supplemental lighting should be provided promptly.

3. Fertilizer-induced yellowing: Over-fertilizing, using too high a concentration, or even not lacking fertilizer at all can cause pothos leaves to turn yellow. When too much fertilizer is applied, the pothos leaf surface becomes thick and lusterless, and the leaves look unrelaxed; old leaves turn yellow and drop. This can be reduced by flushing with water. When fertilizer is lacking, the leaf color becomes pale, appearing light green or yellow, and fertilizer should be supplemented promptly; in severe cases, the potting soil should be replaced.

II. Solutions for Yellow Spots on Pothos

The solutions for yellowing pothos leaves should be adjusted according to the cause of the yellowing. Since pothos can be propagated by cuttings, each node on its stem has a leaf bud, and taking just one section for planting will allow it to grow. So when the leaves of a grown pothos turn yellow severely, you can remove the rotten roots, pick off the yellow leaves, and replant the cuttings. Note that when growing in water, you should change to fresh water. You can also cut off vine sections whose leaves have not yet turned yellow and replant them. During planting, bury two to three nodes; for water culture, also use two to three nodes, and change the water once every three to four days (cooled boiled water is best). Right after planting, do not expose to direct strong light; place it in a location with weaker light. In about 20 days, the newly planted pothos will take root and grow. From Juqiao网

What Causes Yellowing Pothos Leaves and What to Do About It

Flower and Bonsai Network introduction: Many flower enthusiasts grow pothos at home. Pothos (scientific name: Epipremnum aureum), also known as golden pothos and devil's ivy, belongs to the Araceae family, genus Epipremnum, and is native to Moorea in French Polynesia.^[3]It has naturalized in tropical rainforests across Southeast Asia, South Asia, South China, the Solomon Islands, Africa, and the West Indies of Central America as humans introduced it. It is a perennial woody vine. It prefers shaded and humid environments and is now commonly cultivated as a foliage plant in homes. Due to its climbing characteristics, it is suitable for hanging basket planting or growing on totem poles. The problem most commonly seen with pothos is yellowing leaves. What should be done about yellowing pothos leaves? Today, the Flower and Bonsai Network editors share an article about what causes yellowing pothos leaves. Let's take a look.

Reasons for Yellowing Pothos Leaves

Generally speaking, when growing pothos, too much or too little water, too strong or too weak sunlight, and too much or too little fertilizer can all cause leaves to turn yellow. The general reasons for yellowing pothos leaves are as follows.

I. Water problems. Improper watering is one of the reasons for yellowing pothos leaves. Pothos is a vine plant that loves humid growing environments, but overwatering or not watering at all can cause pothos leaves to turn yellow. If the leaves are dull and lusterless, it is due to overwatering; if the leaf tips or edges are withered and dry, it is caused by underwatering.

Pothos needs an appropriate amount of water. Do not overwater. Follow the principle of "water when dry, water thoroughly when you water." The water quality is best if it is clean tap water. Do not casually pour leftover drinking water into the pot. Soil that is too wet will prevent the plant's roots from breathing, causing yellow leaves and rotten leaves.

II. Lighting problems. This vine plant, pothos, generally prefers to grow in shady places. Exposure to blazing sun or strong light will cause the plant's leaf tips and leaf margins to wither and yellow spots to appear on the leaves, greatly affecting its appearance. If placed in a dark environment for a long time, pothos leaves will also turn yellow because they cannot carry out photosynthesis.

Solution: When growing pothos, it is best to place it under appropriate light, such as incandescent lamp light.

III. Fertilizer problems. The amount of fertilizer used when growing pothos is also one of the reasons determining whether the leaves turn yellow. If too much fertilizer is applied, the concentration is too high, or fertilizer is lacking, all of these can cause yellowing pothos leaves. When too much fertilizer is applied, the pothos leaf surface becomes thick, lusterless, and feels uncomfortable; old leaves turn yellow and drop.

Solution: To prevent pothos leaves from turning yellow, apply fertilizer in appropriate amounts and at appropriate times. It is best to apply thin fertilizer frequently, in small amounts multiple times. Remember not to apply too much fertilizer at once, otherwise it will cause nutrient excess, and the plant cannot fully absorb it, leading to root burn and yellow leaves. When fertilizing, it is best to use more organic fertilizer. You can also appropriately use beer as fertilizer; simply mix beer with water at a 1:1 ratio and spray it on the stems and leaves of the pothos.

IV. Root rot causing yellowing pothos leaves: manifested as pale color in young leaves, appearing yellow or light green.

Solution: Remove the rotten roots and place them in a ventilated area to dry. After the wounds heal, return them to the pot. Note that there must be no standing water in the pot.

V. Sudden environmental changes causing yellowing pothos leaves:

The cause is sudden environmental changes, with too great a sudden change in temperature, humidity, and light, or repotting that damaged the roots requiring the plant to recover, resulting in yellowing leaves.

Solution: There is no need to worry in this situation. You can take measures to reduce the degree of environmental change and wait for it to adapt.

Pothos Care Methods for Office and Home

(1) Pothos bought in winter are all shipped from Guangzhou to all parts of the country. Pothos has generally been exposed to cold, so placing it indoors will result in rapid yellowing of leaves. After these cold-damaged leaves completely yellow and drop, new ones will still grow again after Spring Festival.

(2) Generally, newly bought pothos needs about 1 month to adapt to a new environment. Yellow leaves at the bottom are normal. However, remember: do not directly pull off yellow or dead leaves; cut them from the middle of the leaf stalk. This avoids excessive water loss and extra wounds from direct tearing, which could cause the upper leaves to turn yellow as well.

(3) Pothos is not afraid of shade, but it also cannot be grown well in a very dark environment! You can periodically move its position to a place with good light; but it cannot be exposed to blazing sun!

(4) To grow pothos well, appropriate ventilation is also needed.

(5) For watering, you can moisten the pole, which is covered with aerial roots. Periodically spray the leaves with a bit of nitrogen fertilizer and water the soil with a diluted ferrous sulfate solution.

(6) If the leaves have already turned very yellow! Be sure to pay attention to controlling watering; too much or too little is both bad! At this time, place the pothos in a well-ventilated place with light! (

7) Pothos is afraid of freezing; after freezing, it will turn black until it dies.

(8) When the pothos has grown very long and climbs over the top of the pole, cut it off, or turn the top around and let it climb downward. Do not let it grow randomly.

There are multiple reasons for the lowest leaves of pothos turning yellow: occasional occurrence is normal metabolism during the growing season, but the interval is relatively long; overwatering or drought; watering should follow "dry then wet"; after autumn cools, fertilizing should stop; indoors, pay attention to light and ventilation; in winter, appropriately spray water. In addition, when some pothos have many yellow leaves, the cause is mostly in the roots. Yellow leaves are only the surface symptom; if the roots rot, the leaves turn yellow.

What Causes Yellowing Pothos Leaves and What Solutions Are There

Pothos is a typical foliage plant. Its leaves are emerald green, and it has a very good decorative effect when placed indoors. Pothos is also often placed in offices to soothe tense nerves and relax tired eyes. So what causes yellowing pothos leaves?

What causes yellowing pothos leaves:

Improper watering

Both overwatering and underwatering affect the growth of pothos and cause leaves to turn yellow. If the leaves are dull yellow and lusterless, and new shoots shrivel, it indicates overwatering. If the leaf edges are withered and dry, new leaves grow well, but old leaves turn yellow and drop, it is underwatering.

Imbalanced lighting

Pothos prefers shade, but still needs light. However, too strong sunlight or insufficient light will both make pothos dull and lusterless. Under strong light, the leaf tips and leaf margins of pothos wither, and yellow spots appear on the sun-facing parts. On the contrary, if kept in a dark environment for a long time, the leaves cannot get enough light and will also turn yellow.

Improper fertilizing

When pothos is over-fertilized, the leaves become thick but lusterless, curled and unrelaxed, and old leaves turn yellow and drop. When fertilizer is lacking, the leaf color becomes pale, gradually turning yellow from the leaf tip all the way to the root stem.

Solutions for yellowing pothos leaves:

Cut off diseased leaves

Once yellowing leaves are discovered, remove the diseased leaves promptly. If handled in time and with more care and attention, the yellowing condition can be improved early on. If the plant's leaves have turned yellow severely, this method can only superficially remove aged leaves, and other treatments are still needed.

Proper care

Pay more attention to watering, lighting, and fertilizing. Each step should be improved according to need and given more care, and your pothos will surely regain its fresh green.

Unwinding

This method is for pothos with a moss pole. Separate the pothos from the moss pole and rewrap it.

Before the operation, control water for one week and try to wait until the branches are soft before proceeding, so as to avoid breaking the branches.

Use scissors to cut the aerial roots and separate them from the moss pole.

Rewrap the cut branches along the moss pole. Keep healthy branches as much as possible toward the top, and coil yellowing or dropping leaves toward the bottom. When wrapping, arrange them evenly to maintain a neat appearance.

Then provide sufficient water and fertilizer and enough light, and before long it will grow into an upright pot of pothos.

Pruning and renewal

First, directly cut off the yellowed branches and leaves. During pruning, do not directly cut off the root stem.

During pruning, note that you should first prune half of the pothos, cutting off about 20 cm. After new leaves grow, prune the other half.

The length to prune still depends on the plant's own growth condition.
