Scindapsus pictus, commonly called satin pothos, silver pothos, or silver vine, is a species of flowering plant in the aroid or arum family, Araceae, native to Bangladesh, Borneo, India, Java, Peninsular Malaysia, the Philippines, Sulawesi, Sumatra, Taiwan and Thailand.

How this shows up on a Satin pothos
Soft yellow leaves low on the plant, soil still wet
A sour smell from the compost is common on a satin pothos, and the leaves nearest the soil come away when pulled. The surface may look dry while everything beneath it is not.
Its source calls for soil that is moist but well-drained or well-drained. Past that, water in the pot displaces the air the roots need, and damaged roots then fail to supply the leaf blades above them.
Telling it apart: Whether the compost has dried at all since the last watering. A pot that has not dried in a fortnight is answering the question on its own.

Most likely rot at the base of the stem

Why: A stem that is soft or dark at the soil line, in wet compost, has usually been invaded by the fungi and bacteria that thrive where roots and stems sit wet.
What to try:
- Look for any firm, healthy stems or tips above the damage; cuttings from those may root even if the base cannot be saved.
- Throw away the affected compost rather than reusing it, and wash the pot before using it again.
What would settle it: Cut a small slice from the affected stem. Discoloured tissue running up inside it is rot; a clean pale centre means the damage is on the surface.
Most likely too much water for a plant that stores its own

Why: A satin pothos built to survive drought has little use for extra water.
What to try:
- Stop watering and let the compost dry right through.
- Remove soft leaves, and check the base of the stem for rot.
What would settle it: Press a leaf gently. A thirsty succulent leaf is wrinkled and springs back; a waterlogged one is swollen and stays dented.
Most likely cold
- H1C — 5–10°C RHS · read 13 September 2026
Why: Soft, dark patches rather than crisp ones are damaged tissue rather than dried tissue.
What to try:
- Move it away from the glass at night, or keep the curtain on the room side of the satin pothos.
- Leave damaged leaves until new growth appears, then remove the worst of them.
What would settle it: Where the satin pothos sits at night, and what the glass feels like at that hour. Damage that appeared after one cold night, on the side facing the window, is the pattern.
Less likely for a Satin pothos, still possible

What this does not cover
This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
