How it usually goes wrong

Bleached patches on the side facing the glass

On a inch plant the marks are patchy and one-sided. Leaf blades on the shaded side of the vine keep their colour entirely.

Glass concentrates what would be tolerable outdoors, because it holds the heat and removes the moving air that carried it away. Its source describes full sun, partial shade.

Telling it apart: The edge of the damage. Scorch has a sharp boundary; rot and infection have a soft, spreading one.

Dry, curled edges on leaf blades near a heater

A yellow halo sits just inside the brown edge on the inch plant, and new leaf blades often come in already tipped with brown during the heating season.

The edges fail first because they are the end of the plumbing. Penn State Extension cites 30% to 60% as the recommended indoor range, and winter heating regularly takes a room under it.

Telling it apart: What else in the room changed. Edges that browned when the radiators came on point at the air rather than at the watering.

Lower leaf blades collapse and yellow within days of a watering

On a inch plant the yellowing climbs from below. Affected leaf blades feel limp rather than papery, and water sits in the saucer long after it drains through.

The source for this plant describes moist but well-drained soil. Compost that stays saturated loses the air spaces fine roots grow into, and those roots die back first.

Telling it apart: Weigh the pot in your hand. A pot still heavy a week after watering is holding more water than the roots are using.

Routine care

Watering
Water regularly, letting the soil dry between waterings, and water less in winter. Their watery sap can irritate skin.
NC State Extension · read 13 September 2026
Under glass, give bright filtered light and use a peat-free potting compost that is loam-based; during active growth water moderately and feed monthly with a balanced liquid fertiliser, and give little water in winter. In dry weather, water generously.

Feeding
Under glass, use a loam-based, peat-free potting compost and bright filtered light; during active growth water moderately with a monthly balanced liquid fertiliser, and in winter water sparingly.

Propagation
Cutting back leggy growth also provides stem cuttings for propagation.
NC State Extension · read 13 September 2026
In spring or summer, root softwood stem-tip cuttings in water or peat-free cutting compost, then move them into potting compost that is loam-based and peat-free.

Pruning
It can be cut back hard each spring and moved to a sheltered patio outdoors for the summer.

Pests and diseases
Can be troubled by thrips, vine weevil, aphids, mealybugs and red spider mite. Diseases: usually none.

About the plant

Tradescantia zebrina, formerly known as Zebrina pendula, is a species of creeping plant in the Tradescantia genus. Common names include silver inch plant and wandering Jew. The latter name is controversial, and some now use the alternative wandering dude. The plant is popular in cultivation due to its fast growth and attractive foliage. It is used as a groundcover in warm winter climates, and as a houseplant elsewhere.

What this does not cover

The figures above are what published sources say, not measurements of the plant in your room. They say nothing about your pot size, your water, the season, or how far from the glass the plant stands, and those decide more than any figure here does.

Humidity has no species figure because no source read for this site publishes one, and the only temperature published for this plant is a cold floor. The simulator fills those gaps with general figures for its kind of plant, marked as general and listed on how we read sources. Where a toxicity row says the plant was not assessed, that is the absence of a finding and not a finding of safety.

If something is already wrong, the diagnosis tool asks about the soil, the window and the watering, which is where the answer usually is.
