How to save your house plants from winter damage

As the colder months set in and homes across the UK switch on the heating, many houseplant owners unknowingly put their greenery at risk. While a warm room feels like comfort to us, it can spell trouble for tropical plants that thrive in humidity and stable conditions.

To help plant lovers keep their greenery thriving throughout winter, Keira Kay, Plant Expert at online flower and plant company Bloom & Wild, shares her top tips for protecting houseplants from the hidden dangers of central heating.

Why heating can harm your houseplants

With many houseplant species coming from tropical parts of the world, it’s a common misconception that heating will help see them through the colder months. However, the added heat can cause damage to your precious greenery and in some cases, even be fatal.

The biggest culprit? Lack of humidity. Our heating keeps us cosy but can quietly take a toll on our plants, Keira explains. Radiators, fires, and underfloor heating all dry out the air and the plants themselves. Leaves can crisp, edges can brown, and plants may start to wilt even just being nearby a heat source can be enough to cause damage.

For those with underfloor heating, the constant warmth can make roots overheat and become stressed, while the sudden cool-down when it switches off can shock them.

Plants most at risk

Tropical and humidity-loving plants such as ferns, calatheas, and peace lilies tend to struggle the most with dry indoor air.

Hardier species like snake plants and ZZ plants are much more tolerant. A good rule of thumb: the thinner and softer the leaf, the more likely it is to dry out quickly.

How to protect plants from central heating

Keep your distance: Move plants away from radiators, fireplaces, or underfloor heating. If you can feel warmth on your hand, it’s too close for comfort.
Lift them up: Place plants on shelves, side tables, or hanging planters to keep them out of direct warm air currents.
Group them together: Clustering plants helps them share moisture and create a natural microclimate.
Add humidity: Place a small bowl of water near your plants (or even on a radiator) to gently raise moisture levels. Regular misting or a small humidifier can also help.
Avoid draughts: Keep plants away from doors or windows where temperature fluctuates dramatically consistency is key.

What to do if your plant is already suffering

If you notice brown tips or drooping leaves, don’t panic it’s often reversible, reassures Keira. Trim away any damaged parts, move the plant to a more stable, humid spot away from radiators, and water gently if the soil feels dry. Daily misting for a week or two can help revive it. With a bit of consistency, most plants will bounce back once the environment improves.
