As autumn’s chill sets in and homeowners begin to turn on their heating, the challenge of excess moisture and mould in the home returns.
While dehumidifiers and ventilation remain key, and certain tricks can help minimise pesky condensation, nature offers a charming and cost-effective alternative: houseplants that purify the air and absorb moisture.
Plants are not a stand-alone solution for damp and mould, but they complement traditional moisture control methods with the added benefits of aesthetic appeal and cleaner indoor air.
Introducing these greenery champions into your home this winter could help you breathe easier and keep mould at bay naturally.
English Ivy
Known primarily as an outdoor climber, English Ivy is surprisingly effective indoors in tackling airborne mould.
Some studies claim the plant can eliminate up to 78% of airborne mould spores in just 12 hours, because its dense foliage traps them whilst absorbing moisture.
This makes English Ivy ideal for damp spaces like bathrooms.
Care tip: English Ivy thrives in indirect light, but beware, it is toxic to children and pets if ingested.
Peace Lily
The Peace Lily stands out with its elegant white blooms and glossy leaves. This plant filters mould spores and toxins such as benzene and formaldehyde before they settle and begin to grow on your walls.
Favoured for damp environments, Peace Lilies actively reduce moisture in the air, promoting a fresher indoor atmosphere.
Care tip: This plant prefers shaded areas and regular watering. Keep out of reach of cats and dogs, as peace lilies can cause irritation if chewed.
Snake Plant
As well as filtering out moisture and harmful toxins, the Snake Plant uniquely releases oxygen at night, boosting indoor air quality round the clock.
It is almost indestructible, requiring minimal watering — perfect for busy households or the not-so-green-fingered.
Care tip: Avoid overwatering Snake Plants to prevent mould growth on the soil and plant base.
Boston Fern
Boston Ferns are natural humidifiers and thrive in moist environments, as they are native to tropical climates.
They absorb excess moisture in the air while filtering out harmful mould spores, making them excellent in bathrooms or kitchens.
Care tip: Position for indirect sunlight with good air circulation, and water consistently to maintain lush fronds.
Palm plants
Palm varieties like Lady Palm and Bamboo Palm excel at reducing indoor humidity, and therefore prevent mould growth on walls and surfaces.
Their wide leaves also capture airborne toxins, refreshing your living space naturally.
Care tip: Keep leaves dust-free to maximise air-purifying efficiency.
Tips for using plants to combat mould
- Position plants strategically in higher moisture areas such as bathrooms, kitchens, or basements.
- Combine with good ventilation and avoid drying clothes indoors.
- Rotate plants for optimal sunlight exposure and monitor soil moisture to prevent fungal growth on plants themselves.
- Consider potential toxicity for pets and children when selecting plants.
