Water or Soil?
For most Australian indoor gardeners, water propagation is the easiest and most successful starting point. It allows you to visually monitor root health and easily spot rot before it kills the cutting. Soil propagation, while skipping the transplant-shock phase, requires precise moisture management that many beginners struggle to get right in variable Australian climates.
Why Your Devil’s Ivy Cuttings Are Dying
If you’ve ever placed a Devil’s Ivy cutting in a jar of water only to watch the stem turn black, slimy, and mushy within two weeks, you are making one of three critical errors:
- You cut in the wrong place: Snipping a leaf by its stem will never grow roots. You must include a node (the small brown bump on the main vine).
- You are suffocating the cutting: Leaving the same tap water in a jar for a month depletes oxygen, guaranteeing root rot.
- You left leaves submerged: Any foliage sitting below the water line will rot and poison the water.
Devil’s Ivy (Epipremnum aureum) is genetically wired to multiply quickly. Whether you are fixing a leggy plant, saving a dying vine, or multiplying your collection for free, this guide cuts out the guesswork.
Why Your Devil’s Ivy Cuttings Are Dying
If you’ve ever placed a cutting in a jar of water only to watch the stem turn black, slimy, and mushy within two weeks, you are likely making one of three critical errors. Identify your mistake below to rescue your next batch.
1. You Cut in the Wrong Place
Snipping a single leaf by its fragile stem will never grow roots. Without the specialised plant cells located on the main vine, the leaf just slowly rots.
The Fix
You must include a node (the small brown bump on the main vine). Cut 1-2cm below this bump.
2. Suffocating the Cutting
Leaving the same tap water in a jar for a month depletes all the oxygen. Without oxygen, bacteria take over, guaranteeing a slimy, black stem.
The Fix
Empty the jar, rinse the cutting, and replace with fresh, room-temperature water every 5 to 7 days.
3. Submerged Leaves
Nodes grow roots under water; leaves do not. Any foliage sitting below the water line will quickly decay, turning the water toxic for the cutting.
The Fix
Strip the bottom 1-2 leaves off the vine before placing it in water. Ensure only bare stem and nodes touch the water.
Don’t throw in the towel just yet.
Devil’s Ivy (Epipremnum aureum) is genetically wired to multiply quickly. Whether you are fixing a leggy plant, saving a dying vine, or multiplying your collection for free, correcting these three mistakes will virtually guarantee strong, white roots.
Before You Start (Tools You'll Need)
Setting yourself up for success starts with the right equipment. You don’t need a professional greenhouse, but having these items ready will drastically improve your success rate:
- Sharp secateurs or plant snips (Clean cuts prevent rot).
- Clear propagation jar (For water propagation).
- Indoor potting mix (A premium, free-draining brand).
- Perlite (To add essential drainage).
- Rooting hormone (Optional, but highly recommended for soil).
- Gloves (To protect your hands, as the sap contains calcium oxalate).
- Spray bottle (For gentle watering).
Understanding the Node: The Golden Rule
The absolute most critical step in propagating Devil’s Ivy is knowing exactly where to make your cut. You cannot simply snip off a leaf by its stem and expect it to grow roots.
A cutting must contain a node.
The node is the small, slightly swollen bump or joint on the main vine where a leaf attaches. Scientifically, nodes contain meristematic tissue—plant cells capable of producing new roots when stimulated by natural plant hormones called auxins.
In your home, this is the exact spot where new water or soil roots will emerge.
How to make the cut:
- Sanitise your secateurs with rubbing alcohol.
- Locate a healthy vine with plump, vibrant leaves.
- Find a node, and make a clean, angled cut about 1 to 2 centimetres below it.
- If your cutting has multiple leaves near the bottom, strip the lowest leaf off so you have a bare section of stem with an exposed node. (Leaves left submerged in water or buried in soil will simply rot).
Method 1: Water Propagation (Step-by-Step)
Water propagation is the most popular method for beginners because you can watch the root development in real-time.
- Step 1: Place your prepared cutting into a clear glass jar.
- Step 2: Fill it with room-temperature, filtered water (or tap water left out overnight). Ensure the node is submerged, but keep the leaves above the water line.
- Step 3: Place the jar in a warm spot with bright, indirect light (like an east-facing window). Keep it away from heaters or direct air conditioner drafts.
The Maintenance: We’ve found that many Australian beginners change the water too infrequently, which is one of the most common causes of propagation failure.
Change the water every 5 to 7 days to replenish the oxygen the new roots desperately need. In warmer parts of Australia during summer, water may need changing more often because it warms up and stagnates quickly.
Method 2: Soil Propagation (Step-by-Step)
While water propagation is fun to watch, roots grown in water are structurally different from roots grown in soil. Moving a water-propagated plant into soil later causes a brief period of transplant shock. Propagating directly into soil skips this transition phase.
- Step 1: Take your cutting and optionally dip the bare node in a rooting hormone powder.
- Step 2: Fill a small nursery pot (about 10cm wide) with a 50/50 blend of indoor potting mix and perlite.
- Step 3: Poke a hole in the soil with a pencil and insert the cutting, burying the node completely.
- Step 4: Press the soil gently around the stem and mist lightly with a spray bottle.

Root Development Timeline (What to Expect)
Readers love knowing what to expect. If you are propagating in water in standard spring/summer conditions, here is your week-by-week guide:
- Week 1: Fresh cut. The stem calluses over.
- Week 2: Tiny white “nubs” or short roots appear at the node.
- Week 3: Roots lengthen significantly (2-4 cm).
- Week 4: Secondary roots (tiny hairs branching off the main roots) begin to appear.
- Week 5–6: Ready for potting!
When to Pot Up: Don’t just rely on length. The signs that your cutting is ready for soil include multiple healthy roots, the presence of secondary branching roots, firm/white root tissue, and occasionally, new leaf growth starting at the top.
Best Time to Propagate Across Australian States
While indoor plants are somewhat insulated, they still respond to the natural light cycle and ambient temperatures of your home. Winter growth slows significantly, and heatwaves can stress delicate cuttings.
| Australian Region | Best Time to Propagate Devil’s Ivy |
|---|---|
| Sydney (NSW) | September – March |
| Melbourne (VIC) | October – February |
| Brisbane (QLD) | Nearly Year-Round |
| Perth (WA) | Spring & Early Summer |
| Adelaide (SA) | October – March |
| Hobart (TAS) | Late Spring – Summer |
Internal Linking Note: During summer, be sure to keep your parent plant healthy too. Read our guide on [Fixing Leggy Devil’s Ivy Vines] and [Training Devil’s Ivy to Climb].
7 Common Propagation Mistakes
- Cutting above the node instead of below it (resulting in a node-less stem that will never root).
- Submerging leaves in water, which introduces rot immediately.
- Using dirty scissors, transferring bacteria to the fresh cut.
- Changing water too rarely, depriving the roots of oxygen.
- Keeping cuttings in direct afternoon sun, which boils the water in the jar.
- Potting into dense garden soil, suffocating the delicate new roots.
- Moving the cutting too much before roots can establish a grip.
Troubleshooting: Why Isn’t My Cutting Growing?
- Stem turning black/mushy: Root rot. You likely didn’t use clean secateurs, or you left a leaf in the water. Cut away the black portion (if there’s a node left higher up) and start fresh.
- Leaves turning yellow: Usually a sign of too much direct light or lack of nutrients if it’s been in water for months.
- No roots after 4 weeks: Likely too cold (especially in southern states during winter) or not enough indirect light.
- Mould in water/slimy stem: The water has stagnated. Wash the jar with soap, rinse the cutting gently, and refill with fresh water.
Can Devil’s Ivy Live Permanently in Water?
Yes, it absolutely can! This is a very popular decorative hydroponic setup. However, water alone doesn’t contain the nutrients the plant needs long-term.
To keep it alive permanently in water, you must provide nutrients by adding a tiny drop of liquid indoor plant fertiliser to the jar once a month. Keep in mind that growth will usually be slower than a plant established in soil.
Can I Propagate Every Variety?
Yes! The propagation method is identical whether you have a standard Golden Pothos, a Marble Queen, Neon, Snow Queen, N’Joy, or Manjula. (Note: Satin Pothos, or Scindapsus pictus, is not a true Pothos, but it propagates using the exact same node-cutting method).
Our Recommended Propagation Kit
If you want to upgrade from old jam jars to a dedicated setup, here is what we recommend for Australian homes:
- Propagation Station: A wooden stand with glass bulbs (looks great on a windowsill).
- Pruning Snips: Small, sharp bypass secateurs.
- Premium Rooting Hormone: For soil propagation.
- Indoor Potting Mix & Perlite: For the perfect airy mix.
Important FAQS: How to Propagate Devil’s Ivy:
Can I propagate Devil’s Ivy from just a leaf?
No, a leaf without a node won’t produce a new vine. You need an intact node (the small bump on the stem) to grow proper roots and shoots.
Why are my cuttings rotting in water instead of rooting?
In warm weather, water loses oxygen quickly. If you aren’t changing the water every few days, cuttings can suffocate and rot. Also, ensure your cuttings aren’t too long; stick to 10-15cm lengths.
Can I use tap water from the garden hose to propagate?
Standard tap water is generally fine, but never use soft water from home water softeners, as the sodium content is highly toxic to plants. Rainwater remains the absolute best choice.
How long does water propagation actually take?
During a warm Aussie spring or summer, you should see roots emerging in roughly 2 to 4 weeks. Try to keep the ambient room temperature above 20°C for the fastest strike rate.
Do my cuttings need fertiliser while sitting in water?
Yes! Water entirely lacks the natural nutrients found in potting mix. You can add a liquid all-purpose fertiliser diluted to a quarter of its normal strength to keep your cuttings fed and vigorous.
The roots look brown and mushy. What do I do?
This is root rot, usually caused by soil staying constantly wet and suffocating the root system. Rinse the roots, trim away the mushy parts with sterilised shears, and spray the healthy roots with 1 part hydrogen peroxide to 4 parts water before repotting.
My pot sits on a concrete slab. Is the summer heat an issue?
Concrete radiates extreme heat that can literally cook the roots inside a pot. You must elevate the container on “pot feet” to allow cooling airflow underneath and prevent the pot from acting as an oven.
The potting mix has become hard and water runs straight off.
Old potting mix can become “hydrophobic,” actively repelling moisture. Plunge the entire pot into a larger tub of tepid water for a few hours to thoroughly rehydrate the peat, then treat the topsoil with a quality soil wetter.
Why are the leaves wilting even though the topsoil is wet?
This is a classic sign of root suffocation. Check if your balcony tiles have created a vacuum seal against the bottom drainage holes. Elevate the pot immediately so the excess water can drain away freely.
I have tiny flies around my indoor Devil’s Ivy. How do I fix this?
Those are annoying fungus gnats. Apply a layer of gnat barrier granules over the surface of the potting mix. This stops the females from laying their eggs and breaks the insect’s life cycle.
Why are the leaves turning brown and curling up?
Curling, brown leaves often point to severe underwatering, low humidity, or getting scorched by too much direct sun. Check the soil—if it feels completely dry, give the plant a thorough watering immediately.
Is a terracotta or plastic pot better for my balcony?
Terracotta breathes beautifully (protecting against root rot) but dries out rapidly in extreme summer heat. Lightweight fiberglass or thick plastic pots with excellent drainage holes are often the best compromise for outdoor spaces.
