Syngonium (Syngonium podophyllum): care, watering and propagation cuttings

To care for a syngonium, place it in bright, indirect light, water when the surface of the potting mix has dried slightly, keep it above 15 °C in winter, and give it a moss pole if it starts to climb. Syngonium, botanically known as Syngonium podophyllum, is an easy-care indoor aroid, known for its arrowhead-shaped green, pink, or variegated leaves.

Every figure in this guide comes from a named source, from the RHS (Royal Horticultural Society) to American university extension services. It is grown like its cousins, pothos and philodendron, and you can find our full range in the Syngonium collection.

🌿 Syngonium podophyllum: a plant whose leaves change with age

The syngonium most commonly grown indoors is Syngonium podophyllum Schott, the accepted species according to Plants of the World Online, Kew's database, which describes it as a vine native to humid tropical forests from Mexico to tropical America. Arum auritum, Pothos auritus, and Xanthosoma gracile are simply former synonyms.

Its distinctive feature is its leaves: Kew notes that throughout the Syngonium genus, leaf shape varies as the plant matures and the stems contain a milky latex.

Young syngoniums have simple arrowhead-shaped leaves measuring 7.5 to 17.5 cm; as they mature, the leaves become compound, with 3 to 11 leaflets, according to the University of Florida's growing guides (UF/IFAS).

🔎 Syngonium at a glance

Here is the verified profile of syngonium. The accepted name and native range come from Kew.

Growth habit, size, and toxicity are based on NC State Extension (North Carolina State University), which describes juvenile leaves as oval, heart-shaped, or arrow-shaped, becoming lobed at the intermediate stage, and the plant as bushy at first, then climbing as it ages.

Its common English names are arrowhead vine and American evergreen; in French, it is also called plante flèche. Do not confuse it with Syngonium angustatum, a related species that the Atlas of Florida Plants (University of South Florida) distinguishes by its often rough-textured stems, whereas those of S. podophyllum are smooth.

Essential growing guidelines, at a glance.

📍 Where to place a syngonium: exposure, light, and temperature

Place your syngonium near a bright window, away from direct sunlight on the leaves. The RHS recommends bright, indirect light for green cultivars and bright but filtered light for variegated cultivars, and classifies the plant as H1A: it should be grown under cover year-round, above 15 °C.

NC State Extension warns that full sun can burn or fade the foliage. As for warmth, the University of Florida's guides (UF/IFAS) recommend 65 to 80 °F, or around 18 to 27 °C, to maintain leaf color, and note that cold damage can occur below 55 °F, around 13 °C.

☀️ Ideal location: Near an east- or west-facing window, or set back from a south-facing window behind a sheer curtain. Pink and variegated syngoniums need the brightest spot in the room.

📅 When to move it: In spring, when growth resumes; avoid moving it in midwinter between a warm room and a cold one.

🏡 Syngonium outdoors in summer? Only when nights stay mild, in bright shade and sheltered from the wind. The RHS sets a minimum of 15 °C, and UF/IFAS reports cold damage at around 13 °C: bring it indoors as soon as nights turn chilly.

🪴 Repotting a syngonium: which potting mix or substrate to choose

Repot your syngonium in spring, when the roots circle the bottom of the pot or emerge through the drainage holes, using a container with drainage holes that is only slightly wider. The RHS recommends houseplant potting mix in fresh, well-drained soil.

Clemson University's extension service recommends a mix of equal parts peat or coco fiber, vermiculite, and perlite, while UF/IFAS grows syngonium in a substrate with a pH of 5.5 to 6.5.

Our aroid potting mix follows this airy approach; to compare mixes, read our guide to aroid potting mix. Drainage comes from the substrate and the pot's drainage hole, not from a layer of clay pebbles at the bottom.

✂️ Syngonium care: watering, fertilizer, and pruning

Syngonium care comes down to three things: water moderately, feed during the growing season, and prune to maintain the shape you want. UF/IFAS recommends letting the surface of the substrate dry slightly before watering and, in winter, watering less often without letting the root ball dry out. The RHS says the same thing in different words: water generously during the growing season and sparingly in winter.

There is no fixed watering schedule that works for every home: let your finger in the potting mix decide.

💧 Watering: Push a finger into the potting mix: if the surface is still damp, wait. If it has dried slightly, water until it drains out, then empty the saucer. UF/IFAS recommends using room-temperature water, as cold water can mark the leaves in winter.

🌱 Fertilizer: According to the RHS, apply a balanced liquid fertilizer every 3 to 4 weeks in spring and summer. Clemson describes it as a light feeder: use a reduced dose, and even less for a plant in low light.

✂️ Pruning: The RHS recommends reducing the height in spring if needed. Cut just above a node with clean tools and gloves: the sap can irritate the skin. Pinching back long stems keeps the plant compact.

💧 Air humidity: UF/IFAS says the plant looks its best at 40 to 60% humidity, and Clemson notes that it tolerates lower levels. Group your plants or place the pot on a tray of wet pebbles, without misting.

🔹 Leaves: Wipe them with a lint-free cloth, as UF/IFAS recommends: this reduces dust and helps you spot pests earlier.

🍂 Syngonium through the seasons

Growth resumes in spring: this is the time to repot, restart fertilizer, shorten overly long stems, and add a support pole. In summer, the plant grows quickly: keep an eye on watering, direct sun, and the appearance of spider mites. In fall, water less often, stop fertilizing, and take a few backup cuttings.

In winter, keep it above 15 °C as the RHS recommends, away from cold windows and radiator drafts, and water sparingly. To increase humidity safely, read how to increase humidity and misting: useful or not?.

🌱 Propagating syngonium: in water or soil

Syngonium is very easy to propagate from cuttings. UF/IFAS describes the simplest method: a single-node cutting (the point where a leaf attaches), rooted in warmth with bottom heat, keeping the substrate at around 70 to 75 °F, or about 21 to 24 °C. The RHS recommends stem-tip or single-eye cuttings in summer, also with bottom heat.

Cut a healthy section of stem just below a node, remove the bottom leaf, and insert it into a light, moist substrate in bright light out of direct sun.

Many plant enthusiasts also root it in a glass of water or in moist sphagnum moss; to choose a method, see our guide to propagating in water or potting mix.

🐛 Syngonium problems: yellow leaves, causes, and solutions

Yellow leaves on a syngonium most often point to a watering or nutrition issue: UF/IFAS attributes yellowing older leaves to nitrogen deficiency or substrate that dries out too much, and leggy plants to insufficient light.

Diseases are mainly bacterial: Penn State Extension describes translucent spots at the edges of leaves that turn dull green and are ringed by a bright yellow halo, as well as foul-smelling soft rot caused by Erwinia; it advises against watering over the foliage.

NC State lists aphids, mealybugs, and spider mites, and also mentions thrips; for the latter, see our guide to thrips on houseplants.

🌸 Our syngonium varieties: pink, Neon Robusta, Mojito, Arrow, White Butterfly

All these forms are grown like the species; descriptions are from UF/IFAS where cited, otherwise from our product pages. The RHS rule of thumb: the more variegated or pink a syngonium is, the more bright, filtered light it needs to retain its colors. If you’re undecided, our Mystery Syngonium Box brings together several varieties to discover. Here are the ones we grow.

🎨 Climbing syngonium: support, mature leaves, and pairings

To grow a climbing syngonium with mature leaves, give it a support. Clemson explains that as the plant matures, its petioles lengthen and it can be trained onto a moss pole, trellis, or bamboo stake, while UF/IFAS notes that a totem, trellis, or other support is needed for vertical growth.

Our guide to supports for climbing plants explains how to set one up, and a clear support keeps things discreet. If you prefer a compact shape, simply pinch back the lengthening stems.

As for pairings, it enjoys the same filtered light as pothos and philodendron; for a cascading display, compare the vines in our guide to trailing indoor plants.

⚠️ Is syngonium toxic to cats and dogs?

Yes. The ASPCA (American Society for the Prevention of Cruelty to Animals) classifies Arrow-Head Vine, Syngonium podophyllum, as toxic to dogs, cats, and horses due to its insoluble calcium oxalates.

Reported signs include mouth irritation, pain and swelling of the mouth, tongue, and lips, excessive drooling, vomiting (except in horses), and difficulty swallowing.

NC State Extension classifies its toxicity as moderate, affecting all parts of the plant, including the sap, and notes that it can cause contact dermatitis; the RHS recommends wearing gloves. If ingested, call your veterinarian.

For a room shared with a pet, see our lists of non-toxic plants for cats and non-toxic plants for dogs.

✅ Our expert tips for success

Growing a syngonium successfully mostly comes down to giving it light without direct sun and not watering it out of habit: bright, indirect light, let the surface of the potting mix dry slightly before each watering, a minimum of 15 °C in winter, and a pot with drainage holes. Prune or pinch it in spring for a dense clump, or give it a support to see its mature leaves emerge.

Choose a variety to suit your light: a green syngonium can handle a medium-light spot, while a pink or variegated syngonium needs the brightest spot. Finally, always keep a backup cutting.
