Winter is the time when mould patches are more likely to develop on windowsills, walls and nearby furniture. As the warm air inside the home presses against cold surfaces, such as windows and exterior walls, condensation occurs leading to water droplets.
When there is a lack of ventilation, the humidity in the home increases, and this makes the perfect breeding ground for mould and mildew.
While houseplants aren’t a cure-all, they can reduce excess moisture in the air to help protect the home against mould.
Experts from Beards & Daisies said: “Certain houseplants are renowned for their ability to absorb moisture through a process known as transpiration.
“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.”
The experts added: “By strategically placing these plants in damp areas, homeowners can create a natural humidity buffer.”
Ideal areas can include bathrooms, kitchens, and laundry rooms (or where you dry laundry if you don’t have a laundry room, per se).
Peace lilies are also great at improving indoor air quality by reducing airborne toxins that can contribute to mould spore growth.
The peace lily plant “absorbs pollutants and convert them into nutrients, helping to clean the air naturally”.
Jo, the founder of Beards & Daisies – and author of the houseplant guide The Unkillables – emphasised the practical benefits of houseplants in moisture control.
“Incorporating a few carefully chosen houseplants can make a real, measurable difference in controlling moisture and mould,” said Jo. “Especially in the cooler months when these issues tend to peak.”
Jo added: “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.”
