How to save a pothos with yellowing leaves and root rot?
When grown indoors, too little or too much water, light that is too strong or too weak, and too much or too little fertilizer can all cause pothos leaves to turn yellow or even the roots to rot. What should you do when your pothos keeps turning yellow and its roots rot? Don't be afraid! Master the following few tricks, and your pothos will have glossy green leaves that climb all over the wall.
What to do when pothos leaves turn yellow and the roots rot. 1. Pothos leaves turning yellow: too little waterSigns: the leaf tips and leaf edges become scorched and dry, newly emerged young leaves grow normally, and old leaves turn yellow and drop off.
Solution: as soon as you notice a lack of water, water immediately, and water thoroughly in one go, that is, until water flows out of the small holes at the bottom.
2. Pothos leaves turning yellow: improper lightSigns: both new and old leaves are on the yellowish side, which indicates insufficient light, while scorch marks on the leaves indicate the light is too strong.
Solution: the best spot for pothos is a bright living room, where it can receive scattered light without being scorched by direct sunlight.
3. Pothos leaves turning yellow: too much fertilizerSigns: the leaves are thick and fleshy but lack gloss, and the old leaves turn yellow and drop off.
Solution: if it has not been long since you fertilized, you can flush the roots with clean water so the excess fertilizer dissolves in the water and flows out through the small holes at the bottom. If it has been a while since you fertilized, then the only option is to change the soil.
4. Pothos roots rottingSigns: the leaves turn yellow, wilt and fall over, and in severe cases of root rot you can even see the stems rotting!
Solution: if the root rot is not severe, you can cut away the rotten parts of the roots, then disinfect them and replant (the potting soil must be replaced with new soil). If the root rot is especially severe, then just cut off the relatively healthy stems and propagate them from cuttings or grow them in water!
5. Pothos roots rotting and the temperature being too lowSigns: the leaves wilt, turn black and fall over.
Solution: in this season the chance of cold damage is relatively small, but once cold damage occurs, cut off everything above the soil, then put it in a warm place and wait for it to grow new leaves.

Why the leaves of water-grown pothos turn yellow
Sudden environmental change
Generally, a newly bought pothos needs about 1 month to adjust to a new environment, and yellow leaves at the bottom are normal. But remember: do not pull yellow or dead leaves off directly; cut them off from the middle of the leaf stalk instead. This avoids excessive water loss and extra wounds caused by pulling them off directly, which would otherwise make the upper leaves turn yellow too.
Unsuitable light and temperature
Pothos likes a hot, humid, semi-shaded environment and cannot tolerate cold; its overwintering temperature should not be below 10°C. It is sensitive to temperature, dislikes direct sunlight in summer, and its leaves easily turn scorched yellow and drop off under strong light. In winter it grows well indoors under bright scattered light, and during the growing period it has a relatively high demand for water.
Poor water quality
Water-grown pothos may also turn yellow because there are bacteria in the water. If you grow it in tap water, it may be due to a high bleaching powder content in the water. Pothos itself cannot tolerate low temperatures, and prolonged low temperatures combined with a large amount of water can cause root rot, which leads to an insufficient water supply from the roots; in the end the leaves near the roots start to turn yellow and the leaves at the top lose their gloss.
Solutions for yellow leaves on water-grown pothos
Plenty of sunlight
It should be placed where there is plenty of scattered light, and during the growing period the leaves should be misted frequently. Spraying 0.2% monopotassium phosphate can restore the vivid markings on the leaves. Use a relatively large growing container (with a large water surface) if possible, and if conditions allow, oxygenate the water.
Fertilizing
Spraying 1% urea is also fine. Every living thing has a life cycle, and it may also simply have aged; just let nature take its course. Only after it turns withered and yellow will it grow new leaves, so there is no need to worry.
Change the water frequently
Also, for water-grown pothos change the water once a week, and if conditions allow, adding some maifan stone or small pebbles will effectively reduce the occurrence of yellow leaves. When changing the water, rinse the roots well and cut off any diseased roots. Do not put in too much water; just enough to cover the roots. When growing it in water, it is recommended to wrap the roots of the pothos together with soil and sawdust in a cloth before putting it in the water.
What to do when pothos leaves turn yellow. What causes pothos leaves to turn yellow
1. Sudden environmental change causing pothos leaves to turn yellow:Yellow leaves caused by a sudden environmental change, too great a sudden change in temperature, humidity and light, or repotting that damaged the roots and requires a period of recovery.
Solution: there is no need to worry in this situation; you can take measures to reduce the degree of environmental change and simply wait for it to adjust.
2. Overwatering causing pothos leaves to turn yellow (water yellowing):
The young leaves are dull yellow and lack gloss, the old leaves show no obvious change, the stems are thin and yellow-green, and the new shoots shrivel and stop growing, which indicates overwatering.
Solution: take the pothos out of its pot and place it in a ventilated, shady spot, then put it back in the pot once the soil ball has dried.
3. Long-term lack of water causing pothos leaves to turn yellow (drought yellowing):
Yellowing from lack of water is different from yellowing from too much water. Yellowing from lack of water means the leaf tips or edges become scorched and dry, and the old leaves turn yellow and drop off from the bottom up, but the new leaves grow relatively normally.
Solution: just be careful to water enough and water thoroughly.
4. Scorching sun causing pothos leaves to turn yellow (sunscorch yellowing):Strong direct sunlight easily causes the leaf tips and leaf edges of pothos to become scorched, and yellow spots appear on the parts of the leaves facing the sun.
Solution: just move it to a shady, ventilated spot.
5. Insufficient sunlight causing pothos leaves to turn yellow (light-deficiency yellowing):
When kept in a shaded environment for a long time, the leaves cannot get enough sunlight and cannot form chlorophyll, so the whole plant's leaves turn yellow and then drop off.
Solution: move it to a place with relatively plenty of light.
6. Too much fertilizer causing pothos leaves to turn yellow (fertilizer yellowing):
Yellowing caused by too much fertilizer or too high a concentration shows as dry brown tips on the new leaves; generally the leaf surface is thick and fleshy but lacks gloss and is uneven and not smooth, and the old leaves turn scorched yellow and drop off.
Solution: stop fertilizing immediately, and in severe cases flush out part of the fertilizer with a large amount of clean water, or replace the potting soil.
7. Long-term lack of fertilizer causing pothos leaves to turn yellow (nutrient-deficiency yellowing):
It shows as the young leaves becoming paler in color, turning yellow or pale green, while the old leaves are relatively normal or gradually turn from green to yellow.
Solution: check the potting soil, and if it has become dry and caked, replace the soil. Usually apply light fertilizer frequently and occasionally water with some alum water.
8. Root rot causing pothos leaves to turn yellow: it shows as the young leaves becoming paler in color, turning yellow or pale green.
Solution: remove the rotten roots and put the plant in a ventilated spot to dry. Once the wounds have healed, put it back in the pot, and be careful that there is no standing water in the pot.
