1. Overwatering and imbalance humidity level
The most widely recognized reason for yellowing leaves among Pothos plants is irregularly maintained soil dampness specifically, overwatering. Possibly water your Pothos when the top 20 to 25% of the soil in the pot is dry. The soil ought to stay moist, yet not wet or spongy.
In the colder time of year, you can permit your plant to dry out somewhat more between 2 consecutive watering segments, yet make sure to help the dampness around your plant with normal clouding, a humidifier, or a rock plate. When you water your Pothos, ensure you give sufficient water so that fluid streams from the waste opening at the lower part of the pot and into the saucer.
It’s critical to dispose of any overabundance of water in the saucer and not to allow your plant to sit in any standing water. Your Pothos would not answer well to “wet feet,” which will make the roots decay and lead to the inevitable passing of the plant. Switching off and on between very dry and wet soil from badly coordinated watering can make pressure and influence the leaves of your Pothos to yellow.

Giving legitimate and reliable soil dampness with proper and timely watering is significant in focusing on Pothos. Low humidity and dry soil make leaves hang and brown on their edges, later followed by whole yellowing, sometimes browning, and leaf drop. Clouding the leaves of your Pothos frequently will build the humidity.
2. Improper provision of the light source
Pothos will show the best growth when it is put in bright to medium indirect (circuitous) daylight, however, they will adjust to bring down light if necessary. Nonetheless, assuming put in exceptionally low light, yellow leaves might create. Be cautious you’re not putting your Pothos in full sun-when presented to coordinate daylight for a really long time, the foliage will consume.
It favors splendid, backhanded light, yet will endure medium and low light. The variegation will be more articulated in a more splendid light. Your Pothos would not do well in direct daylight the daylight can consume the foliage. So use indirect sunlight to avoid the yellowing of leavesNorman, D.J. and G.S. Ali, Pothos (Epipremnum aureum) Diseases: Identification and Control in Commercial Greenhouse Production: PP340, 7/2018. EDIS, 2018. 2018(4). Read.
3. Insect pests
A debilitated or focused Pothos is more powerless to bug invasions. Sap-sucking bugs like insect parasites can deplete your plant of dampness. This issue rapidly shows itself by yellowing flyers and fronds. Scale, mealybugs, and bug vermin happen often in indoor circumstances.
On the off chance that not killed right off the bat, these little nuisances multiply and move from the beginning frond parts into little hiding spots. The puncturing mouths of the bugs exhaust your plant and speed up yellowing, particularly on the off chance that your Pothos is as of now unfortunate from unfortunate lighting, a lack of supplement, or inappropriate soil dampness.
These oval-shaped bugs leave a white fine substance on the leaves and little eggs tracked down around the leaves and stems. This substance is intended to safeguard the bugs while they feed on the sap of the foliage, causing yellowing, leaf senescence, and twisted leaves. Scale can be difficult and challenging to get rid of.

In the event that a synthetic insecticidal issue doesn’t determine, you might have to dispose of your Pothos to try not to spread the issue to your different houseplants. Whiteflies are regularly eliminated with insecticidal cleansers. However, since they have wings and stay nearby the plants, they can likewise be tricked away with tacky snares. Sticky traps are a reasonable control for thrips flying bugs. Guarantee you prune away any infected portion of the plant to advance new and healthy growth.
The bug can be taken out or washed off the leaves in the sink. Bigger gatherings require a more strong arrangement, for example, neem oil, to eliminate the issue. While managing mealybugs utilizing your picked insecticidal, ensure you eliminate every one of the eggs too to prevent the invasion from spreading to different houseplantsGilman, E.F., Epipremnum aureum.

4. Root rot of pothos varieties
Pothos root rot can be brought about by overwatering, or contagious disease in the soil. Leaf staining is typically joined by a horrendous smell. At the point when pothos has Pythium root decay, the roots look dark and soft; mature leaves are yellow and tumble off the plant. (With bacterial leaf spot infection, water spots will show up with yellow coronas on the leaf undersides.) Root decay is brought about by excessively soaked soil, which can be a consequence of overwatering, unfortunate seepage, or weighty soils.
Decayed roots will be yellow, brown, or dark and feel soft. Harmed attaches should be removed, then, at that point, the plant repotted in a sterile preparing blend. The treatment procedure relay on this protocol is explained below;
- Tip the plant pot on its side, thump the side of the pot to slacken the soil, then delicately slide the plant out being mindful so as to try not to tear any roots.
- Wash the roots either utilizing regular water or a shower hose.
- The harmed roots will require cut off with one or the other scissors or pruners. However, before you begin clipping, have something close by to disinfect your instruments after each cut. Use scouring liquor (70% isopropyl) or hydrogen peroxide 3%.
It tends to be controlled cautiously wash the roots with lukewarm water.
Then, at that point, spread the entire plant out on a table to dry out. At last, re-pot, giving the plant new, new fertilizer to sustain it back to well-beingZhang, Q., J. Chen, and R. Henny, Direct somatic embryogenesis and plant regeneration from leaf, petiole, and stem explants of Golden Pothos. Plant cell reports, 2005. 23(9): p. 587-595. Read.
5. Nitrogen deficiency in soil
Many plant leaves become yellow in trouble, typically brought about by the absence of a lack of nitrogen in the soil. On the off chance that it is the more seasoned leaves becoming yellow, this is a certain indication of nitrogen inadequacy. Potassium is deficient with regards to when the leaf has yellow edges, so you really want to painstakingly evaluate the soil. Nitrogen-based organic and inorganic fertilizers are suggested for soil to comprehend the deficiency symptomsWu, Y., X. Cai, and Y. Tang, Outcomes of Low-Temperature Stress on Biological Alterations within Pothos (Epipremnum aureum) Leaves. Life, 2022. 12(9): p. 1432. Read.
6. Ethylene damage in pothos
Ethylene can damage, and also presents like an infection, however it is not. Brought about specific fungicides might make leaves become yellow and beige. Ethylene harm specifically as a rule happens in a cooler climate, similar to fall and winter. Ethylene makes pothos foliage become yellow, then tan to light brown.

Plants might seem shriveled despite the fact that soil dampness is satisfactory. Guarantee satisfactory ventilation is available in the nursery. Apply ethylene medicines cautiously in a multi-crop framework. Stay away from blended heaps of flower, foliage, and vegetable items during transportation if conceivableSaxena, K., R. Yadav, and D. Solanki, Rhaphidophora aurea: A Review on Phytotherapeutic and Ethnopharmacological Attributes. Read.
7. Bacterial wilt
At the point when pothos leaves yellow, it can flag difficult issues like the contagious sicknesses pythium root decay and bacterial leaf spot. Root decays are frequently brought about by soil-occupying parasites and excessively soggy soil; unfortunate waste and plant swarming favor their turn of events.
Pothos with yellowing leaves might show roots. Pothos with yellowing leaves might show root decay. At the point when the plant has pythium root decay, mature leaves are yellow and fall and the roots look dark and soft. With bacterial leaf spots, you’ll see water spots with yellow radiances on the underside of the leaves. This condition will foster in currently pushed plants confronting root decay.
If your pothos with yellowing leaves as root decay, give them the most ideal social consideration. Be certain your plant is put where it gets sufficient daylight, be certain that its soil depletes well, and limit water to ideal sums. Try not to fog the plant since root decay growths flourish in clammy circumstances.
Diseased foliage ought to be eliminated at the earliest hint of a bacterial or parasitic disease. It is important to eliminate the entire contaminated and infected leaf. Then, at that point, the rest of the plant can be blessed to receive forestall further harm, utilizing a copper fungicideNelson, S., Bacterial leaf blight of aglaonema. 2009. Read.
8. Mineral especially Mn toxicity
Manganese toxicity is one more issue to watch out for. While bacterial wilt, bacterial blights, and southern curse can happen in more young seedlings and immature plants, overabundance measures of the component manganese are all the more promptly an issue in more established pothos plants. Such abundance might make the plant look unhealthy; however, manganese’s harmfulness is brought about by a lot of manganese in the soil.

Manganese toxicity is most regularly seen in nursery establishes that assimilate an excess of manganese from the business manures they have been taken care of with. Utilizing manure time after time or in too high focus additionally turns the leaves yellow. Less use of fertilizers in already mineral-rich soil is the only solution for the Mn toxicity faced by pothosSojeetra, N.H. and R. Acharya, A review on ethnomedicinal claims and spread of Pothos scandens L. European Journal of Medicinal Plants, 2020. 31(5): p. 22-28. Read.
9. Yellowing after re-potting
The justification behind pothos becoming yellow after repotting is typically a direct result of relocation shock and an increase in moisture content around the roots. Bigger pots contain more soil which dries out more slowly than the pothos is familiar with which can bring about root decay and turn the leaves yellow.
Bigger pots have a limit with regards to additional soil and hence more dampness, which can change the rate at which the soil dries out after watering. Furthermore, different circumstances change in the wake of repotting which can turn the leaves yellow, for example,
- Pots without a drainage hole in the base (making an abundance of water pool around the roots).
- The utilization of saucers, trays like plates, and external pots can all trap moisture.
- The soil might have been compacted after preparing (lessening the oxygen around the roots).
10. Maturation and yellowing of leaves
Pothos leaves most commonly become yellow at the base as they mature. As the singular plants develop longer the pothos concentrates on developing the leaves toward the finish of the plant and guides less energy to the leaves at the foundation of the plant making them become yellow and drop off.
Pothos are climbers in their local climate with every plant becoming higher into the trees. The leaves toward the baseline of the plants are bound to get light and out contend with other climbing plants in the backwoods, hence the pothos focuses on the growth of these leaves.
This implies there is less energy for the leaves at the lower part (base) of the plant, so if the lower leaves on your pothos are becoming yellow and drop off regardless of the remainder of the pothos seeming solid, then this is a characteristic piece of the plant’s development and not an indication of sickness or diseaseZhao, J., et al., Plant regeneration via direct somatic embryogenesis from leaf and petiole explants of Epipremnum aureum ‘Marble Queen’ and characterization of selected variants.
