POTHOS
Leggy Growth & Yellowing Leaves
Once a full, trailing cloud, your pothos is now a few long bare strings with leaves only at the ends โ and the base leaves are yellowing. This is the most reversible problem in the whole clinic.

WHAT YOU'RE SEEING The symptoms
The shape gives it away before the colour does: stems, stems, and more stems.
Vines have long bare stretches โ 10 cm (4 in) or more between leaves โ with the leaves getting smaller the further out they grow. The pot looks thin and hollow in the middle. Yellow leaves appear, mostly the older ones near the base. If your plant is a variegated type (marble queen, golden), new leaves are coming in plainer and greener than the ones the plant had when you bought it. That fading pattern is the plant quietly telling you it's light-starved.
MOST LIKELY CAUSES, IN ORDER Start at the top
- 1. Not enough lightThe cause of legginess, full stop. Reaching for light, the vine extends the gaps between leaves and lets the shaded base leaves go. Yellowing plus stretching together is the classic signature.
- 2. It has simply never been prunedPothos grows from the tip. A vine that's never cut keeps extending one direction and never branches โ bare at the base, leafy at the end, by design. Even a well-lit plant goes stringy without the scissors.
- 3. Watering whiplashRepeatedly drying to a crisp then flooding stresses leaves yellow, base first. Unlike the monstera pattern, this yellows leaves on a plant whose soil mostly dries out between waterings.
- 4. Rootbound and hungryThick roots circling the pot, water running straight through, growth slowing to nothing โ an old plant in exhausted soil will drop its oldest leaves to feed the tips.
- 5. Cold draftsA vine trailing over a winter windowsill or a heating vent gets chilled or cooked at the tips. Seasonal and local โ it affects the parts near the draft, not the whole plant.
HOW TO CONFIRM Two minutes of detective work
- Measure the gapsLeaf spacing under about 5 cm (2 in) is a happy vine. Long, consistent gaps of 10 cm or more mean the plant has been reaching for light for a long time.
- Read the variegationCompare the newest leaves to the oldest. Variegation that's fading toward plain green is the plant adapting to low light โ it makes more green to catch what light there is.
- Check the distance to the windowLight falls off fast indoors. A pothos three metres from the window lives in what a plant experiences as a cave, even if the room looks bright to you.
- Look underneathRoots poking out of the drainage holes, or a root ball you can barely dent with a finger, confirm cause #4 โ time to repot as part of the fix.
THE FIX, STEP BY STEP The prune-and-return
- Cut the vines back hardWith clean scissors, cut each long vine back to a few leaves from the base โ always just above a node (the bump where a leaf meets the stem). This feels drastic. It is also exactly what the plant is waiting for: each cut wakes a dormant bud.
- Turn the trimmings into cuttingsCut the removed vines into sections with one or two nodes each. Nothing gets wasted โ these are how you refill the pot.
- Root the cuttings in waterStand them in a glass with the nodes submerged, on a bright sill. White roots appear in one to three weeks. Change the water weekly.
- Plant the rooted cuttings back inWhen roots are 5 cm (2 in) long, poke them into the top of the same pot between the old stems. Ten or twelve cuttings turn a hollow pot into a bush.
- Fix the lightMove the plant to bright, indirect light โ near a window, not metres from one. Shift it closer gradually over a week so leaves don't scorch in a sudden blast of sun.
- Settle the wateringWater when the top half of the soil is dry, drain fully, and feed lightly once a month in spring and summer. New growth should come in with tighter spacing โ that's how you know it worked.
When to stop
A pothos almost never needs tossing โ it's one of the toughest plants in the house. The exception: stems that are black and mushy starting at the soil line, with rot travelling up every vine. Cut each stem back until the inside is firm and green with a living node; if you truly cannot find one firm, green node on the whole plant, let it go and start a cutting from a friend's plant. Otherwise, any green node is a restart waiting to happen. (Note: pothos is toxic to cats and dogs if eaten โ hang it high, which, conveniently, is also where the light is better.)
