Yellowing leaves on Monstera deliciosa are caused by too much or too little watering
Cause
Too much water causes root rot in Monstera deliciosa, while too little water leaves the plant short of water and growing poorly; both situations cause yellowing leaves.
Solution

What to do when Monstera deliciosa leaves turn yellow: Causes and solutions for yellowing Monstera deliciosa leaves
Because Monstera deliciosa is a very good indoor ornamental plant, many people like to grow it, but during cultivation you may encounter yellowing leaves, so what should we do? Let's take a look together at the causes and solutions for yellowing Monstera deliciosa leaves.
1. Sudden environmental changes cause Monstera deliciosa leaves to turn yellow: The cause is sudden environmental changes, with soil, temperature, humidity and light changing too much all at once. Monstera deliciosa was originally a parasitic plant, and its well-developed root system is made up of fleshy roots, which have high requirements for loose, breathable soil. Clayey and slightly clayey soils will affect root growth to varying degrees. If the soil is not breathable enough or is not changed for a long time, it may cause the soil to harden, affecting the respiration of Monstera deliciosa, so that it grows poorly and its leaves turn yellow.
Solution: For household potted Monstera deliciosa, the growing medium can be a mixed soil made of 2 parts aged loess, 1 part honeycomb coal ash, and 1 part chicken manure. This can both ensure the breathability of the potting soil for Monstera deliciosa and meet the fertilizer requirements needed for growth.
2. Overwatering causes Monstera deliciosa leaves to turn yellow (water yellowing): Too much water causes root rot in Monstera deliciosa, and this situation causes yellowing leaves.
Solution: Monstera deliciosa should be watered regularly, soaking through each time, keeping the soil surface slightly dry; when the air is dry, sprinkle water on the environment and on the Monstera deliciosa leaves.
3. Long-term lack of water causes Monstera deliciosa leaves to turn yellow (drought yellowing): Too little water leaves the plant short of water and growing poorly, and this situation causes yellowing leaves.
Solution: Water regularly with a sufficient amount of water
4. Exposure to strong sun causes Monstera deliciosa leaves to turn yellow (scorch yellowing): Placing Monstera deliciosa in strong light will cause its leaves to be scorched and turn yellow.
Solution: Monstera deliciosa needs shading in summer.
5. Dry air causes Monstera deliciosa leaves to turn yellow: When the air is dry, it causes the leaves of Monstera deliciosa to turn dull yellow.
Solution: Keep indoor ventilation good; you can also place Monstera deliciosa indoors for viewing during the day and move it outdoors at night.
6. Insufficient sunlight causes Monstera deliciosa leaves to turn yellow (light-deficiency yellowing): Monstera deliciosa is shade-tolerant, but keeping 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 deliciosa some scattered light.
7. Too low a temperature causes Monstera deliciosa leaves to turn yellow: The suitable growth temperature for Monstera deliciosa 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, and below 5°C they are prone to cold damage, causing the leaves to turn yellow.
Solution: In winter, the roots of Monstera deliciosa need appropriate warmth to enhance the plant's cold resistance, but do not place Monstera deliciosa directly on a radiator or next to an air conditioner.
8. Long-term lack of fertilizer causes Monstera deliciosa leaves to turn yellow (fertilizer-deficiency yellowing): Iron is a necessary raw material for plants to synthesize chlorophyll. If the soil or fertilizer lacks iron, it will affect the synthesis of chlorophyll in Monstera deliciosa, thus 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 deliciosa leaves to turn yellow: Monstera deliciosa gray leaf spot, also known as leaf blight, is a common disease of Monstera deliciosa. 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 time, cut off diseased leaves or diseased tissue of leaves, and destroy them centrally. For chemical control, spray 0.5% Bordeaux mixture or 50% Tuzet 1000x solution.
