Reasons and Solutions for Yellowing Leaves on Monstera
There are many reasons why Monstera leaves turn yellow. If you notice yellowing leaves, you can cut off the yellow leaves and place the plant in a well-ventilated spot. Generally, the causes of yellowing Monstera leaves include unsuitable soil, overwatering or underwatering, too much or too little light, low temperatures, insufficient fertilizing, poor ventilation, and so on. Let's take a look below at what to do when Monstera leaves turn yellow!
Yellowing leaves caused by unsuitable soil
[Cause of yellowing] Monstera (Monstera deliciosa) was originally an epiphytic plant, and its well-developed root system consists of fleshy roots, so it has high requirements for loose, breathable soil. Clayey and slightly clayey soils will affect root growth to varying degrees. If the soil has poor breathability or is not changed for a long time, the soil may become compacted, affecting the respiration of the Monstera, which leads to poor growth and yellowing leaves.
[Solution] For potted Monstera at home, the growing medium can be a mixed soil made of 2 parts matured loess, 1 part honeycomb coal ash, and 1 part chicken manure. This ensures both the breathability of the potting soil for Monstera and meets the fertilizer requirements needed for growth.
Yellowing leaves caused by improper watering
[Cause of yellowing] Overwatering or underwatering can both cause Monstera leaves to turn yellow. Too much water can cause root rot in Monstera, while too little water causes the plant to suffer from water shortage and grow poorly. Both situations can cause yellowing leaves in Monstera.
[Solution] Monstera should be watered regularly, thoroughly at each watering, keeping the soil surface slightly dry. When the air is dry, sprinkle water on the surrounding environment and on the Monstera leaves.
Yellowing leaves caused by improper light
[Cause of yellowing] Too much or too little light can both cause Monstera leaves to turn yellow. Monstera is shade-tolerant, but leaving it in a shaded environment for a long time will affect photosynthesis and cause the leaves to turn yellow. At the same time, Monstera should not be placed in strong light, as strong light will scorch the leaves and cause them to turn yellow.
[Solution] In summer, Monstera should be shaded, and it is best to give it some scattered light.
Yellowing leaves caused by low temperatures
[Cause of yellowing] The suitable growing temperature for Monstera is 20-25°C. In winter, the nighttime temperature should not be lower than 10°C during the seedling stage. Mature plants can tolerate 5°C for a short time. Below 5°C, frost damage easily occurs, causing Monstera leaves to turn yellow.
[Solution] In winter, the roots of Monstera need proper warmth to enhance the plant's cold resistance, but do not place Monstera directly on a radiator or next to an air conditioner.
Yellowing leaves caused by insufficient fertilizing
[Cause of yellowing] Iron is an essential raw material for plants to synthesize chlorophyll. If the soil or fertilizer lacks sufficient iron, it will affect the synthesis of chlorophyll in Monstera, causing the leaves to lose green color and turn yellow.
[Solution] For yellowing leaves caused by iron deficiency, apply alum fertilizer water or spray a 0.1-0.3% ferrous sulfate solution.
Yellowing leaves caused by poor ventilation
[Cause of yellowing] Poor ventilation can cause Monstera leaves to turn yellow from stuffiness.
[Solution] Keep the indoor ventilation good. You can also place Monstera indoors for viewing during the day and move it outdoors at night.
What to Do When Monstera Leaves Turn Yellow: Causes and Solutions for Yellowing Monstera Leaves
Because Monstera is a very good indoor ornamental plant, many people like to grow it, but during cultivation you may encounter yellowing leaves on Monstera. What should we do? Let's take a look below at the causes and solutions for yellowing Monstera leaves.
1. Sudden environmental changes cause Monstera leaves to turn yellow: The cause is sudden environmental changes, with too great a sudden change in soil, temperature, humidity, and light. Monstera was originally an epiphytic plant, and its well-developed root system consists of fleshy roots, so it has high requirements for loose, breathable soil. Clayey and slightly clayey soils will affect root growth to varying degrees. If the soil has poor breathability or is not changed for a long time, the soil may become compacted, affecting the respiration of the Monstera, which leads to poor growth and yellowing leaves.
Solution: For potted Monstera at home, the growing medium can be a mixed soil made of 2 parts matured loess, 1 part honeycomb coal ash, and 1 part chicken manure. This ensures both the breathability of the potting soil for Monstera and meets the fertilizer requirements needed for growth.
2. Overwatering causes Monstera leaves to turn yellow (water yellowing): Too much water can cause root rot in Monstera, and this situation will cause yellowing leaves in Monstera.
Solution: Monstera should be watered regularly, thoroughly at each watering, keeping the soil surface slightly dry. When the air is dry, sprinkle water on the surrounding environment and on the Monstera leaves.
3. Long-term water shortage causes Monstera leaves to turn yellow (drought yellowing): Too little water causes the plant to suffer from water shortage and grow poorly, and this situation will cause yellowing leaves in Monstera.
Solution: Water regularly with a sufficient amount of water.
4. Scorching sun causes Monstera leaves to turn yellow (sunburn yellowing): Placing Monstera in strong light will scorch the leaves and cause them to turn yellow.
Solution: In summer, Monstera should be shaded.
5. Dry air causes Monstera leaves to turn yellow: Dry air can cause Monstera leaves to turn yellow from stuffiness.
Solution: Keep the indoor ventilation good. You can also place Monstera indoors for viewing during the day and move it outdoors at night.
6. Insufficient sunlight causes Monstera leaves to turn yellow (light-deficiency yellowing): Monstera is shade-tolerant, but leaving it in a shaded environment for a long time will affect photosynthesis and cause the leaves to turn yellow.
Solution: It is best to give Monstera some scattered light.
7. Low temperatures cause Monstera leaves to turn yellow: The suitable growing temperature for Monstera is 20-25°C. In winter, the nighttime temperature should not be lower than 10°C during the seedling stage. Mature plants can tolerate 5°C for a short time. Below 5°C, frost damage easily occurs, causing Monstera leaves to turn yellow.
Solution: In winter, the roots of Monstera need proper warmth to enhance the plant's cold resistance, but do not place Monstera directly on a radiator or next to an air conditioner.
8. Long-term nutrient deficiency causes Monstera leaves to turn yellow (nutrient-deficiency yellowing): Iron is an essential raw material for plants to synthesize chlorophyll. If the soil or fertilizer lacks sufficient iron, it will affect the synthesis of chlorophyll in Monstera, causing the leaves to lose green color and turn yellow.
Solution: For yellowing leaves caused by iron deficiency, apply alum fertilizer water or spray a 0.1-0.3% ferrous sulfate solution.
9. Pests and diseases cause Monstera leaves to turn yellow: Monstera gray spot disease, also known as leaf blight, is a common disease of Monstera. When the disease is severe, it can cause leaves to wither and die. It usually occurs more severely when the indoor temperature is low or after exposure to smoke or pest damage, and the disease mostly occurs on old leaves.
Solution: For prevention and control, strengthen cultivation management and pay attention to controlling room temperature, which should not be too low. Control pests in a timely manner, cut off diseased leaves or diseased tissue on the leaves, and destroy them in a centralized manner. For chemical control, spray 0.5% Bordeaux mixture or a 1000-fold dilution of 50% Tuzet.
