How it usually goes wrong

Edges of the leaf blades brown while the middle stays sound

On a Swiss cheese vine the browning starts furthest from the midrib and works inward, and it crumbles rather than smears. The centre of each leaf blade is untouched.

Transpiration rises as the air dries, and the tissue furthest from a vein loses first. Penn State Extension notes there is no single humidity figure that suits every indoor plant, which is why this site publishes a range rather than a number.

Telling it apart: Whether the soil is dry too. Crisp edges with damp soil point at the air; with dry soil, at the watering.

Long bare stretches of stem between leaf blades

Nothing browns and nothing drops; the Swiss cheese vine simply makes less, and what it makes is stretched and thin.

A plant stretches when the light is short of what it evolved for. Its source describes partial shade, and a room darker than that sets the vine reaching.

Telling it apart: Compare the colour of the newest leaf with one grown last year. Paler and smaller together is light; paler at the same size is more often feeding.

Lower leaf blades collapse and yellow within days of a watering

Whole leaf blades yellow at once rather than browning at a margin, and the Swiss cheese vine looks deflated despite soil that has not dried since it was watered.

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
To prevent leaf spots, keep water off the leaves and give the plant good airflow.

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.
