In Brisbane and the Gold Coast, winter isn’t harsh—but the heating indoors can be. While our subtropical climate means we’re lucky to avoid frost and snow, the shift to indoor heating can quietly stress out your indoor plants.
Whether you manage an office, retail space or commercial venue, you might start noticing signs of plant fatigue around this time of year—drooping leaves, dry soil, browning tips. And it’s not because of the cooler weather outside.
It’s the heating inside.
Why indoor heating causes plant stress
Most indoor heating systems—whether ducted, split system or portable—reduce humidity and dry out the air. This has a big impact on tropical indoor plants, which naturally thrive in warm, moist, and stable environments.
In air-conditioned or heated spaces, your plants face a few challenges:
- Lower humidity dries out the leaf surface and soil
- Warm air vents can scorch delicate foliage
- Fluctuating temperatures confuse the plant’s natural growth rhythm
Plants like Peace Lilies, Pothos, Aglaonema and Ferns are particularly vulnerable. These species evolved in humid rainforest conditions—and even Brisbane winters can feel dry to them.
5 Ways to keep indoor plants happy in winter
A few simple changes can help your plants stay vibrant through the cooler months.
1. Check moisture more often
Even though plants grow slower in winter, heating can cause soil to dry out quickly—especially in air-conditioned offices or under heaters.
Tip: Don’t wait for wilting leaves. Feel the top layer of soil and water when it’s dry.
2. Move plants away from direct heat
Heaters under desks, wall vents, and heat sources near pots can create hot spots that stress plants or even burn leaves.
Tip: Aim for bright, indirect light and stable air—not too hot, not too cold.
3. Clean and mist occasionally
Dust builds up more quickly in winter as windows stay closed and heaters kick up dry air. Wipe leaves gently to allow proper light absorption.
Tip: Light misting can also help increase humidity—just don’t overdo it in closed spaces.
4. Reduce watering—but not too much
While plants need less water than in summer, cutting watering too far can be just as harmful. Instead, water based on plant type and environment, not the calendar.
Tip: If your space is well-heated or has low humidity, plants may still need regular hydration.
5. Be cautious with outdoor heaters
If your venue uses outdoor flame heaters (common in hospitality across the Gold Coast), keep pots a safe distance away. Heat damage can happen fast—leaves may shrivel or scorch in just one night.
Tip: If damage occurs, contact your plant technician. Many plants can recover with the right care.
