Satin Pothos Yellow Leaves: Overwatering, Cold or Old Age?

Updated

Why are my Satin pothos leaves turning yellow?

Yellow leaves on a satin pothos most often point to mix that stays too wet, especially in winter when the plant uses less water. Long dry spells, cold air, direct sun and normal shedding of old leaves are the other common causes.

What to do first

Note which leaves are yellow, then feel the mix. If it is wet, stop watering, check the roots and repot rotted plants in well-drained mix. If only an old leaf or two is yellow and new growth is healthy, just remove them.

A yellow leaf on a silver-splashed satin pothos (Scindapsus pictus) stands out, and it’s natural to worry. Start by looking at which leaves are yellow and how wet the mix is. Those two checks narrow the cause quickly.

Clemson Cooperative Extension says yellowing of a whole houseplant is most often a symptom of overwatering. Too little light, too little fertilizer, insects and mites can also cause it.

What you seeMost likely cause
One or two of the oldest leaves yellow; new growth healthyNormal leaf shedding
Yellowing on old and new leaves; mix wet; soft stemsOverwatering or root rot
Lower leaves yellow and crisp; mix dry and shrunkenToo dry for too long
Yellowing or dull patches after a cold spellCold damage
Pale, bleached or scorched patches on the sunny sideDirect sun

Iowa State University Extension says that if a few older inner leaves drop from an otherwise healthy plant, there’s nothing to worry about. Shedding old leaves as the plant grows is normal.

Wet mix: the most common cause

Virginia Cooperative Extension lists the signs of overwatering: yellowing on both new and old foliage, mushy leaves and stems, wilting, leaf drop, a rotten-smelling mix and fungus gnats. Missouri Botanical Garden warns that satin pothos roots may rot in poorly drained soils.

Winter is the risky season. Missouri Botanical Garden says to keep the mix consistently moist while the plant is growing, but to reduce watering and feeding over winter. The RHS says to water sparingly outside the growing season. A plant watered on its summer routine in winter can stay wet for days.

What to do:

  1. Stop watering and let the pot drain.
  2. Slide the plant out and check the roots. Clemson describes rotted roots as brown to black and sometimes soft.
  3. If only some roots are affected, cut them out and repot in fresh, well-drained mix. UConn Home & Garden Education Center suggests an aroid mix, or houseplant mix lightened with extra perlite or orchid bark.
  4. If most roots are gone, root healthy stem tips as cuttings to save the plant.
  5. From then on, let the top 2.5–5 cm (1–2 in) of mix dry between waterings, as UConn suggests.

Iowa State lists other reasons mix stays wet: no drainage hole, water left standing in a saucer or cachepot, old compacted mix, or a pot too large for the roots.

Dry mix

Clemson notes that lower leaves may yellow and die if a plant is too dry for an extended time. Virginia Cooperative Extension adds wilting, brittle leaves, brown edges, curling and mix pulling away from the pot. Water thoroughly until water drains from the hole, then empty the saucer.

Cold and light

  • Cold. NC State gives a best range of 18–29 °C (65–85 °F) and says cooler air is not tolerated. Missouri Botanical Garden warns that temperatures below 16 °C (60 °F) may damage the foliage. Keep the plant off cold windowsills and away from draughts in winter.
  • Direct sun. NC State says direct sunlight is not tolerated. Missouri Botanical Garden recommends bright indirect light. The RHS advises shade from hot sun.
  • Too little light. Clemson lists too little light among the causes of yellowing. Iowa State notes that light that is too low, too high, or changes suddenly can cause leaf drop.

Feeding and pests

Clemson links yellowing and browning of lower leaves to nitrogen or iron deficiency, especially in pot-bound plants. Missouri Botanical Garden suggests feeding monthly in the growing season and cutting back in winter. Repot a plant that has filled its pot with roots.

Missouri Botanical Garden lists scale and mites on satin pothos, plus fungal leaf spot and botrytis. Check leaf undersides and stems with a hand lens. Clemson describes fungal leaf spots as small brown spots with yellowish margins, sometimes with rings or tiny black dots. Spots like these point to disease rather than watering. Remove affected leaves and keep water off the foliage.

Pets

The ASPCA lists satin pothos as toxic to dogs, cats and horses. The RHS notes that it is harmful if eaten and a skin and eye irritant, so wear gloves when trimming.

If the leaves are rolling as well as yellowing, see the pothos curling leaves guide for overlapping checks. For a decision tree that works across species, see why houseplant leaves turn yellow.
