Expert shares top six houseplants to reduce home moisture and prevent mould

With the colder months now upon us, concerns about condensation and mould in homes are on the rise.

This is especially the case for older buildings such as Victorian homes and heritage-listed properties, which tend to have higher humidity and less airflow.

These characteristics make such dwellings prime spots for mould development, posing threats to both health and infrastructure. While houseplants aren't the complete solution, certain types can aid in cutting down excess indoor moisture, making them helpful tools in combating mould issues.

TikTok user Root Growings (@rootgrowings) highlighted their pick of six houseplants that can help stave off moisture at home and consequently prevent mould formation. However, they also caution that some may not be safe for pets.

Their recommendations are English Ivy (which is not pet friendly), Spider Plants, Peace Lilies (not pet friendly), Orchids, Air Plants, and Boston Ferns. Supporting this, meanwhile, experts from Beards & Daisies also advocated the use of houseplants as a mould deterrent in residences.

How houseplants help absorb moisture

Elaborating on how houseplants contribute to moisture absorption, they note that plants like Peace Lilies and the Bird of Paradise excel in removing moisture from the atmosphere via transpiration, Beards & Daisies explain.

"Plants such as Peace Lilies and the Bird of Paradise are particularly effective at pulling moisture from the air, which can help lower indoor humidity levels – one of the primary triggers for mould growth.

"By strategically placing these plants in damp areas, homeowners can create a natural humidity buffer."

Air-purifying qualities

They further explain how certain houseplants can enhance indoor air quality. "Peace Lilies and Snake Plants are known to reduce airborne toxins that can contribute to mould spore growth," they provide as examples.

"These plants absorb pollutants and convert them into nutrients, helping to clean the air naturally – a vital consideration for older homes where ventilation may be limited."

Where to place them

When it comes to positioning, Beards & Daisies recommends: "To maximise the benefits of your houseplants, consider placing them in areas prone to dampness, such as bathrooms, kitchens, or laundry rooms. Boston ferns thrive in these environments and can help maintain optimal humidity levels."

They add: "In historic homes, this can be particularly beneficial, as these spaces often experience higher moisture levels due to frequent use of water."

Expert Insights

Jo, founder of Beards & Daisies and author of 'The Unkillables', concludes by highlighting the practical advantages of houseplants in managing moisture. "Incorporating a few carefully chosen houseplants can make a real, measurable difference in controlling moisture and mould, especially in the cooler months when these issues tend to peak," she says.

"While houseplants are often praised for their aesthetic appeal, their functional role in improving indoor air quality and humidity regulation is frequently overlooked. They not only help with humidity but also contribute to creating a fresher, healthier atmosphere overall.

"It’s a small but effective way to improve your home environment, especially when other ventilation options might be limited during autumn and winter – and let's not forget, houseplants boost your mood too."
