How Often Should You Water Devil’s Ivy in Australia? A Season-by-Season Guide

11 July 2026

Almost every Devil’s Ivy that dies in Australia dies of kindness. Not neglect — kindness. People water it on a schedule, the mix never dries out, the roots suffocate, and the leaves go yellow. If you take one thing from this guide: water the plant, not the calendar.

💡

Quick take: There is no “once a week”. Push your finger in to the second knuckle — if the top 3–5 cm is dry, water thoroughly until it runs out the bottom. If it is still damp, walk away. In an Australian summer that might be every 5–7 days; in a Melbourne winter it can stretch to 3 weeks or more.

🚫 Why Watering Schedules Fail

A schedule assumes nothing changes. But how fast your pot dries out depends on the pot size, whether it is plastic or terracotta, how much light it sits in, how root-bound it is, whether the heating or air-con is running, and what time of year it is. Change any one of those and the “right” interval changes with it.

This makes it dry FASTER	This makes it dry SLOWER
Terracotta pot	Plastic or glazed pot
Bright, warm spot	Low light, cool room
Root-bound (all roots, little mix)	Freshly repotted into a big pot
Summer heat, air-con drying the air	Winter, plant barely growing
Small pot	Large pot with a deep reservoir of mix

👉 The Two Tests That Actually Work

✅ The finger test

Push a finger into the mix to your second knuckle. Dry at that depth? Water. Cool and damp? Leave it. It is unglamorous and it is more reliable than any moisture meter.

✅ The weight test

Lift the pot straight after watering, and remember how heavy it feels. A dry pot is noticeably lighter. Once you know the two extremes, you can tell at a glance.

💧 How to Water It Properly

🚿 The soak-and-drain method

Take it to the sink or shower.
Water slowly and thoroughly until it runs freely from the drainage holes.
Let it drain completely — a good few minutes.
Put it back in its cover pot only once it has stopped dripping.
Never leave the pot standing in a saucer of water.

⚠️

The decorative cover pot is the silent killer. Water pools invisibly in the bottom, the roots sit in it, and the plant drowns while you are congratulating yourself on watering it. Always tip the cover pot out after watering.

🗓️ A Rough Australian Seasonal Guide

Use these as starting points to check, not instructions. Always confirm with the finger test.

Season / setting	Check every…
Summer, warm bright room	5–7 days
Summer, humid (QLD/NT)	7–10 days — humidity slows drying
Winter, heated room	10–14 days
Winter, cool/low light	2–4 weeks — growth almost stops

ℹ️

Winter is when most people kill it. The plant slows right down, but the watering habit does not. If you keep watering weekly through a Melbourne winter, you are watering a plant that is barely drinking.

❓ Frequently Asked Questions

❓ Should I mist my Devil’s Ivy?

It does no real harm, but it does very little good either — the moisture evaporates in minutes. Devil’s Ivy tolerates normal household humidity perfectly well. Correct watering matters far more than misting.

❓ Can I use tap water?

In most of Australia, yes. If your leaves develop brown crispy tips over time, letting water stand for a few hours, or using filtered or rainwater, can help.

❓ The leaves are wilting but the soil is wet. What is going on?

That is the classic sign of root rot, not thirst. The roots have rotted and can no longer take up water, so the plant wilts despite sitting in moisture. Watering more will make it worse.

❓ How do I water a plant in a pot with no drainage hole?

You do not, ideally — drill one or plant into a nursery pot that sits inside it. A pot with no drainage gives you no way to flush the mix and no way for excess water to escape.
