Grape Ivy

Cissus rhombifolia (syn. C. alata)

Vining & TrailingEasyModerate🐾 pet-safe

Good to know: A true grape relative that climbs by curling tendrils, and a rare pet-safe trailing vine. It was the unkillable office plant of the 1970s for good reason.

Through the year 🗓️

☀️ Summer now

Keep it out of hot afternoon sun and stuffy corners. Heat plus stale air invites mildew.

🍂 Fall

Taper watering and feeding as growth slows with the shorter days.

❄️ Winter

Water sparingly and skip fertilizer; it happily tolerates cool rooms down to 60 °F.

🌱 Spring

Pinch tips as growth resumes to force branching, and resume monthly feeding.

The details

Light & placement

Light: Medium to bright indirect; one of the better vines for lower light; no hot direct sun
Ideal PPFD: 100–250 µmol·m⁻²·s⁻¹
Grow-light distance: 18–30 in below LED

Water & feed

Watering method: Water when the top 1–2 in dry, then let it drain fully. It would rather run slightly dry than sit wet: soggy roots are its main killer.
Fertilizer: Balanced liquid feed at ½ strength, monthly in spring–summer.

Home & habit

Soil: Well-draining houseplant mix with extra perlite or bark; pH 5.5–6.5
Humidity: Average (40–50%); tolerates dry rooms
Temperature: 60–80 °F (dislikes heat above 85 °F)
Mature size: Trails or climbs 6–10 ft with tendrils
Repotting: Every 2–3 yrs; happy slightly root-bound
Propagation: Stem cuttings with a node in water or moist soil in spring–summer.

When something looks wrong

Overwatering signs: Yellowing leaves, leaf drop, mushy stems near the soil
Underwatering signs: Dull, drooping foliage; dry leaf edges
Common pests: Spider mites, mealybugs, scale; powdery mildew in stale air

Care notes: Cool rooms, moderate light, and restrained watering. It thrives on the benign neglect that kills fussier vines. Good airflow keeps powdery mildew off the foliage.

Common problems 🩺

The usual suspects when Grape Ivy looks unhappy. Most houseplant trouble is watering or light, not disease — see all plant problems if you are not sure which plant is the culprit.

Webbing and stippled leaves

Likely cause
Spider mites, the most common grape ivy problem indoors.

What to do
Shower it well, raise humidity, and treat weekly with neem until clear.

Brown leaf edges

Likely cause
Dry air or underwatering.

What to do
Keep the soil lightly moist and raise humidity a little.

Dropping leaves

Likely cause
Overwatering or a cold snap.

What to do
Let the top inch dry and keep it above 60°F.
