What to Do When Large-Leaf Pothos Leaves Turn Yellow? Causes and Solutions
Why do large-leaf pothos leaves turn yellow? How to fix it?Nowadays many people place a few potted plants at home for decoration, but during the process of growing and caring for them, problems arise for various reasons, such as yellowing leaves, leaf drop, root rot, and so on, all of which affect the plant's growth. And what this article will discuss today is the causes of yellowing leaves in large-leaf pothos and the remedial care measures.
I. Causes of yellowing leaves in large-leaf pothos and solutions
1 Lack of water
Symptoms: Leaf tips and leaf edges dry out and turn scorched yellow; new tender leaves remain normal, but the older lower leaves turn scorched yellow and drop off.
Solution: Water immediately, giving a thorough soaking in one go; you must see water flowing out from the holes at the bottom.
2 Too much water
Symptoms: The leaves as a whole look dull and lusterless with a yellowish cast, and the newly grown leaves have shrunken tips.
Solution: Stop watering, loosen the soil with a trowel or hook, and at the same time place it somewhere with plenty of indirect light and good ventilation so the moisture can evaporate as quickly as possible.
3 Light problems
Symptoms: Both new and old leaves turn yellow overall; if scorch marks are found on the leaves, it means the light is very intense.
Solution: Place it in a bright living room with plenty of indirect light, and it does not need to receive direct sunlight!
4 Too much fertilizer
Symptoms: The leaves are thick and fleshy but dull, and the older lower leaves begin to turn yellow and drop off.
Solution: If over-fertilizing is discovered right after fertilizing, you can flush the potting soil with clean water so the excess fertilizer dissolves in the water and then flows out through the small holes at the bottom.
If it is discovered long after fertilizing, then the only option is to change the soil.
When fertilizing in the future, be sure to apply light fertilizer frequently~
5 Too little fertilizer
Symptoms: The pothos leaves first fade in color, turning light green, then slowly turn yellow, usually starting from the leaves at the base and then gradually spreading to the top leaves.
Solution: Normally you can water the pothos with fully decomposed rice water, soybean cake water, and so on. Water with rice water diluted at a ratio of 1:4, 1-2 times a week; dilute soybean cake water with water at a ratio of 1:50, once a week.
When repotting the pothos, bury some slow-release fertilizer in the soil, or you can bury a small handful of slow-release fertilizer about once a month, but it must not come into contact with the pothos roots.
6 Root rot
Symptoms: Leaves turn yellow, droop, and wilt; in more serious cases, rotting stems can even be seen.
Solution: If the root rot is not very serious, cut off the rotted parts of the roots, then disinfect and sterilize them, and repot; note that the potting soil must be replaced with new soil
If the root rot is especially severe, select relatively healthy stems, disinfect them, and re-propagate by cuttings, or by water propagation.
II. Care methods for large-leaf pothos
1. Suitable temperature: The suitable growing temperature for large-leaf pothos is 20 degrees, so when the temperature is below 20 degrees, protective measures should be taken, covering the large-leaf pothos with a protective film, or moving the potted large-leaf pothos to a warmer environment for care.

2. Indirect light: Large-leaf pothos does not have very high light requirements and dislikes intense direct sunlight, so do not place it on a balcony; simply move it out to bask in the sun on days when the light is relatively mild.
3. Reasonable watering: Large-leaf pothos does not like its roots to be soaked in damp soil for long periods, otherwise it will cause root rot or pest and disease problems, so water a small, appropriate amount, just enough to keep the potting soil from drying and cracking.
4. Appropriate fertilizing: Large-leaf pothos should be given specially formulated fertilizer; in winter it should be switched to diluted inorganic fertilizer, generally applied once every 15 days. When fertilizing, just apply it to the leaves of the large-leaf pothos without watering the roots, and it will safely get through the winter.
