Plants That Fight Damp
by Northern Life
Certain varieties of house plant reduce moisture in the air.
As the colder months approach, mould becomes an increasing concern in many households. While houseplants aren’t a cure-all, certain varieties can help reduce excess moisture in the air, making them a useful addition to your home’s defence against mould.
The Impact of Humidity in Older Homes
Older properties often struggle with moisture retention due to factors such as inadequate insulation, single-pane windows, and limited airflow. Victorian houses, for example, have unique designs and original materials that can trap humidity, increasing the likelihood of mould growth. Listed buildings may have restrictions that prevent homeowners from making significant alterations to improve ventilation, so understanding these challenges is crucial when addressing mould issues in historic homes.
How Houseplants Help Absorb Moisture
Certain houseplants are renowned for their ability to absorb moisture through a process known as transpiration. Plants that fight damp, such as Peace Lilies and the Bird of Paradise, are particularly effective at pulling moisture from the air. This 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
Beyond moisture control, some houseplants also improve indoor air quality. For instance, Peace Lilies and Snake Plants are known to reduce airborne toxins that can contribute to mould spore growth. 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
To maximise the benefits of your houseplants, consider placing plants that fight dampness 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. This can be particularly beneficial in historic homes, as these spaces often experience higher moisture levels due to frequent water use.
Expert Insights
Jo, founder of Beards & Daisies, says, “Incorporating a few carefully chosen houseplants can make a measurable difference in controlling moisture and mould. 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.”
