Care at a glance

Light

The Goldilocks zone. Not the south-facing windowsill (too hot, too direct), not the back of the room (too dim, growth stalls). Adaptable: happiest in bright indirect light but genuinely tolerant of medium and even fairly low light, where most climbers sulk. Keep it out of hot direct sun, which bleaches and scorches the glossy leaves. If you can't decide, a free phone lux-meter app aimed at the leaf at noon should read between 800 and 1,500 lux.

Watering

Watering kangaroo vine: when the top 2-3 cm of soil is dry, about every 7-10 days. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Keep evenly moist in growth but never waterlogged; allow the surface to dry between waterings. It is more drought-aware than fussy, so let it dry a touch more in the cooler, lower-light months.

Soil and pot

Kangaroo Vine grows best in standard free-draining houseplant mix. An ordinary peat-free houseplant compost with added perlite or bark for drainage is ideal. It is not fussy about soil provided the pot drains freely and roots are not left sitting in water. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Kangaroo Vine sits happiest at around 40-60% humidity and 10-24°C (50-75°F). Comfortable in average household humidity and far more forgiving of dry air than tropical vines. Higher humidity is appreciated but never essential. If you keep the room above 10 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed kangaroo vine sparingly. Feed every four weeks through spring and summer with a balanced liquid houseplant feed at half strength to fuel its vigorous climbing. Reduce or stop feeding in autumn and winter as growth slows. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on kangaroo vine in the Growli community. Each is annotated with the most common cause so you know where to start.

  • Powdery mildewCissus is prone to a white powdery coating in stagnant, humid air. Improve airflow, avoid wetting the leaves, and remove affected foliage.
  • Brown leaf edges or dropUnderwatering, drafts, or excessive heat. Keep watering steady and avoid hot, dry positions near radiators.
  • Leggy, bare stemsToo little light or no pruning. Give brighter light and pinch the tips to encourage branching and density.
  • Yellowing leavesUsually overwatering or a waterlogged pot. Let the soil dry further between waterings and check drainage.

Propagation

Take stem-tip cuttings with a couple of nodes in spring or summer and root them in water or moist soil; they establish reliably in a few weeks. Layering also works well. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Kangaroo Vine is pet-safe. The ASPCA lists the Cissus genus as non-toxic, with Grape Ivy (Cissus rhombifolia) explicitly recorded as non-toxic to cats, dogs, and horses. Kangaroo Vine (Cissus antarctica) is a close relative within the same safe genus and is considered non-toxic to pets. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.

Kangaroo Vine care — frequently asked questions

What is the common name for Cissus antarctica?

Cissus antarctica is most commonly called Kangaroo Vine, but it is also known as Kangaroo Ivy. The names refer to the same species, so care instructions for Kangaroo Vine apply identically to anything sold as Kangaroo Ivy.

How much light does kangaroo vine need?

Kangaroo Vine grows best in medium indirect light (a couple of metres from a window). Adaptable: happiest in bright indirect light but genuinely tolerant of medium and even fairly low light, where most climbers sulk. Keep it out of hot direct sun, which bleaches and scorches the glossy leaves.

How often should I water kangaroo vine?

Water kangaroo vine when the top 2-3 cm of soil is dry, about every 7-10 days. Keep evenly moist in growth but never waterlogged; allow the surface to dry between waterings. It is more drought-aware than fussy, so let it dry a touch more in the cooler, lower-light months. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.

Is kangaroo vine toxic to cats and dogs?

Kangaroo Vine is pet-safe. The ASPCA lists the Cissus genus as non-toxic, with Grape Ivy (Cissus rhombifolia) explicitly recorded as non-toxic to cats, dogs, and horses. Kangaroo Vine (Cissus antarctica) is a close relative within the same safe genus and is considered non-toxic to pets.

What USDA hardiness zone does kangaroo vine grow in?

Kangaroo Vine is rated for USDA zone 9-11 (indoor in most US homes) and RHS hardiness H2. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
