Grape ivy (Cissus rhombifolia) care

Vines & trailers · easy to keep

Last updated 26 October 2026

Grape ivy (Cissus rhombifolia) wants medium to bright indirect light. Water it weekly. Water when the top 2–3 cm is dry. It forgives a missed watering far better than the rex begonia vine does. Pot it in airy compost with bark and perlite. Balanced feed at half strength every second or third watering in the growing season, and repot once a year. Humidity: room humidity is fine. The ASPCA lists it as non-toxic to cats and dogs.

Grape ivy: glossy leaves in three parts on vines that climb by tendrils, like the grapevine it is related to. One of the most tolerant vines for a dim room and dry air, and the easiest member of its genus by a distance.

Watering a Grape ivy

Water weekly. Water when the top 2–3 cm is dry. It forgives a missed watering far better than the rex begonia vine does.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Bright indirect light, no direct sun. This is a jungle vine and the leaves mark easily.

Humidity and temperature

Room humidity is fine. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

An airy mix with bark and perlite. It climbs, and the roots want air as much as water.

Feeding

Balanced feed at half strength every second or third watering in the growing season. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot once a year. Every spring while it is growing fast. Give it something to climb.

Common problems

Powdery white coating
Mildew from still, damp air.

Fix: Improve the airflow; humidity without circulation is what causes it.

Propagation

Node cuttings root in water or sphagnum within a few weeks.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Non-toxic to cats and dogs.

The ASPCA lists Grape Ivy (Cissus rhombifolia) as non-toxic to cats and dogs (checked 26 October 2026).

If your pet has eaten a plant, call your vet, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661. Both are open around the clock and may charge a consultation fee. Take the plant or its label with you.

This is general information, not veterinary advice. We don't test plants: what we say about toxicity follows the ASPCA's published plant list as it stood on 26 October 2026, and that list can change. "Non-toxic" means not poisonous — a pet that eats enough of any plant can still vomit, and fertiliser, pesticide or leaf shine on a plant can harm it. It also only helps if the plant is what you think it is. It covers cats and dogs only; ask your vet about rabbits, birds, reptiles or anything else, and a doctor about children. Read our terms.
