Pothos: lower leaves turning yellow
2 causes GrowingHQ holds specifically for pothos, what separates them, and what is safe to do before you are sure.
What you are looking at
The oldest leaves — those nearest the base — losing their green while the growing tip stays healthy. Extremely common on tomatoes and peppers, and one of the least specific signs in growing: at least four unrelated things produce it, and one of them is the plant behaving perfectly normally.
What it is likely to be on pothos

Not a matter of volume but of frequency: roots need air as well as water, and compost that never dries suffocates them. It kills more houseplants than every pest and disease combined, and its cruellest feature is that the early signs — yellowing, wilting, dropping leaves — look exactly like drought, so the instinct is to water more.
Points towards it
- · a pothos is usually sold in a plastic liner inside a decorative pot with no drainage, so water collects where it cannot be seen
- · the cachepot problem is an indoor one
- · roots short of air yellow leaves along the whole length of every trail at once
Argues against it
- · the compost is dry, so the roots are not short of air — this rules it out entirely.
- · the cream and gold marbling of a golden or marble-queen pothos is variegation the leaf was born with, not something that has happened to it

Take the plant out of its decorative outer pot and tip it over the sink. A pothos standing in two centimetres of unseen water at the bottom of a cachepot is the commonest way this plant is killed, and the yellow leaves are spread along the trails rather than concentrated at the oldest ends — which is what separates it from a plant simply shedding its eldest leaf.
What to do now
Empty the outer pot, and from now on water the plant over the sink and let it drain fully before it goes back in. Wait until the top few centimetres are dry before watering again; a pothos recovers from being too dry in a day and from being too wet over months, so the safe direction to err in is obvious.

Not enough light

Shows as stretched growth with long gaps between leaves, small pale new leaves, loss of variegation, leaning hard towards a window, and — in flowering plants — foliage without flowers. It is the commonest reason an indoor plant fails to thrive while appearing to be watered and fed correctly.
Points towards it
- · a trail in deep shade abandons its oldest leaves nearest the pot and keeps only the growing end
- · the usual setting is a shelf or a corner away from a window
- · it follows a move into a darker spot, or simply the onset of winter in a dim one
Argues against it
- · wet compost explains a yellow pothos leaf better and more urgently than shade does
- · shade thins a trail from its oldest end rather than yellowing every leaf on the plant together
Check this next
Look at the newest growth on a variegated pothos, not the yellow leaves. Fresh leaves coming through plain green, with long bare stretches of stem between them, means the plant has traded its variegation for survival in low light — a genuine light signal, and one that appears well before the old leaves start to go.
What to do now
Move it nearer a window or shorten the trails back to within a foot of the pot so that what light there is falls on leaves worth keeping. Cuttings from the trimmed ends root in water in a few weeks and can be pushed back into the same pot, which is how a bare-topped pothos is made full again.

Narrow it down
This page lists everything at once, which is the right shape for reading and the wrong shape for deciding. The interactive tool asks one question at a time, starting with whichever would separate these causes fastest, and stops as soon as further answers would not help.
Work through it for your pothosOpens with the plant and the symptom already set. Nothing you answer is stored or sent anywhere — the answers live in the address bar and nowhere else.
What this does not cover
These are the causes GrowingHQ holds rules for on pothos — not every cause there is. Where several problems look alike, the honest answer is often that they cannot be told apart by eye, and a page that named one would be guessing. If none of the above fits, the general lower leaves turning yellow page lists causes across all plants, and the Pothos profile lists the problems it is prone to.
