Rhipsalis (mistletoe cactus): care, watering, propagation and varieties

To care for a Rhipsalis, place it in bright but indirect light, plant it in an airy mix for epiphytic cacti, and water it moderately as soon as the top of the potting mix is dry, keeping it just moist in winter.

Nicknamed mistletoe cactus, coral cactus, or spaghetti cactus, Rhipsalis (Rhipsalis baccifera is the most common species) is a forest cactus: it grows attached to branches, not in desert sand. That is why it is just as sensitive to scorching sun and prolonged drought as it is to excess water.

This guide draws on Kew, the RHS (Royal Horticultural Society), NC State Extension (North Carolina State University), and the ASPCA. You’ll find information on light, propagation, diagnosing damaged stems, and choosing species.

🌿 Why choose a Rhipsalis?

Rhipsalis has a striking trailing habit: cascades of slender stems without aggressive spines, perfect for dressing up a hanging planter or the top of a shelf. Depending on the species, the stems are cylindrical, chain-like, or flattened, making it easy to build a whole collection. It flowers indoors in winter or spring, then produces small decorative berries.

It is also safe for pets—a real advantage for a plant cats love to paw at.

🔎 Rhipsalis at a glance

According to Kew (Plants of the World Online, genus Rhipsalis), the genus Rhipsalis Gaertn. comprises about 45 accepted species native to tropical and subtropical America, tropical and southern Africa, the western Indian Ocean islands, and Sri Lanka.

The POWO profile for Rhipsalis baccifera describes it as an epiphytic or lithophytic succulent (growing on trees or rocks) and lists Rhipsalis cassytha among its synonyms.

A study published in Scientific Reports (Correa-Cano et al., 2018) notes that R. baccifera is the only cactus species naturally found in Africa and Sri Lanka.

NC State Extension adds that it is also native to Florida, where it is classified as endangered, and that it can grow to about 9 m (30 feet) long in the understory trees. Finally, the RHS describes green to bluish-green stems reaching a maximum length of 2.5 to 4 m.

📋 Quick care guide

The essential growing guidelines, all in one place.

📍 Where to place a Rhipsalis and when to bring it home?

Place Rhipsalis near a bright window, protected from hot sun: for R. paradoxa, the RHS recommends bright indirect light, a little morning sun, and afternoon shade. NC State Extension classifies it as a partial-shade plant, receiving between 2 and 6 hours of direct sun a day.

In the wild, it grows beneath the canopy: filtered light suits it better than an unshaded south-facing window.

📍 Ideal location: hanging in front of an east-facing window, or set back a little from a west- or south-facing window; a bright bathroom also provides the humidity it likes.

🕰️ Best time: in spring or summer, when the plant is growing; this is also the season for stem cuttings, according to the RHS.

🌳 Outdoors in summer: the RHS H1b rating permits summering it outdoors in a warm, sheltered spot in partial shade; bring it inside before nighttime temperatures drop below 10 to 15°C.

🪴 How to repot a Rhipsalis step by step

The RHS recommends compost for epiphytic cacti: a richer, airier mix than desert cactus potting soil, similar to orchid mix. NC State Extension specifies that it prefers acidic soil (pH below 6), which is sandy and very well drained.

A small pot with drainage holes is enough: too much soil will hold water for too long.

✂️ Everyday Rhipsalis care

Caring for Rhipsalis comes down to one idea: it’s a cactus, but a humid forest cactus. The RHS advises watering moderately during the growing season and keeping the potting mix just moist in winter; NC State Extension recommends watering when the surface of the potting mix is dry, without overdoing it, since standing water causes root rot.

💧 Watering: Check the potting mix by touch: water as soon as the top is dry, using soft or rainwater if possible, then empty the saucer.

💧 Humidity: The high humidity it likes is best provided by a tray of damp pebbles or by grouping plants together, rather than by misting.

🌱 Fertilizer: Apply diluted, low-nitrogen liquid fertilizer once a month during the growing season, as recommended by the RHS.

✂️ Pruning: Shorten stems that are too long or dry in spring; keep healthy segments to propagate.

👀 Check for pests: Inspect the branching stems: mealybugs (RHS), spider mites, and aphids (NC State) can settle there.

🍂 Watering Rhipsalis through the seasons

When should you water Rhipsalis? From spring to late summer, water as soon as the top of the potting mix is dry, without following a fixed schedule: how often you water depends on the light, the pot, and the room temperature. It needs more water than a desert cactus: the RHS recommends moderate watering while it’s growing, not infrequent watering. Water less often in fall.

In winter, the RHS advises keeping the potting mix just moist, and keeping it above the H1b threshold of 10 to 15°C: this is also when flowers often appear, described by NC State as about 1 cm across.

🌱 How to propagate Rhipsalis from cuttings

Stem cuttings are the easiest way to propagate Rhipsalis: the RHS says it can be grown from seed at 19 to 24°C or from stem cuttings in spring and summer. Cut a healthy segment a few centimeters long with a clean tool, then leave the cut end to dry and callus in the air, in the shade, for a few days.

Then insert it just barely into slightly moist potting mix for epiphytic cacti, in bright light away from direct sun. Water propagation also works, but transferring the cutting to soil is more challenging; compare the two approaches in our guide to propagating in water or potting mix.

For a fuller hanging planter, place several cuttings in the same pot.

🐛 Common problems: causes and solutions

A Rhipsalis that turns yellow, goes soft, or dries out is almost always signaling an issue with watering, light, or temperature. Here are the most common symptoms, their causes as documented by the RHS and NC State Extension, and how to correct them. If the stems are soft at the base, follow our guide to root rot: causes and how to save your plant.

🌸 Rhipsalis varieties

Here are the Rhipsalis varieties most sought after in France, with verifiable botanical details, including our arrangements. The Kolibri Greens set of 2 Rhipsalis in silver ceramic pots, 9 cm in diameter, is also in our catalog, but is not currently available online.

🎨 What plants go well with a Rhipsalis?

Rhipsalis shares its needs with other epiphytic plants that enjoy filtered light and an airy potting mix. Its closest cousin in our plant guides is the zigzag cactus, another epiphytic cactus. It pairs naturally with orchids, as in our set: check out our complete orchid care guide.

For a mixed hanging display, pair it with the string of hearts (Ceropegia woodii).

And if you’re unsure whether to choose a forest or desert cactus, read our cactus and succulent guide, then browse our hanging plants, cacti and succulents, and bathroom plants.

⚠️ Is Rhipsalis toxic to cats and dogs?

No, the available information is reassuring. The ASPCA (American Society for the Prevention of Cruelty to Animals) lists mistletoe cactus, under the name Rhipsalis cassutha, as non-toxic to dogs, cats, and horses. NC State Extension also lists it as non-toxic to these three animals in its Rhipsalis baccifera profile.

These assessments apply to mistletoe cactus; we couldn’t find a dedicated profile for other species in the genus. A cat chewing on its stems will mainly damage the plant: hang it out of reach, and consult a veterinarian if your pet shows any unusual symptoms after eating a plant.

✅ Our expert tips for success

Three things make for a thriving Rhipsalis: bright light without harsh sun, a well-draining potting mix for epiphytic cacti, and moderate watering once the top layer is dry. If anything seems off, check the base of the stems first (watering), then their color (light). Keep it above 10–15°C (50–59°F) in winter, and propagate stem segments to make the hanging plant fuller.
