UK households are being urged to add one common houseplant to their bathroom to help fight mould as autumn weather sets in. With steam from hot showers, poor ventilation, and a drop in outside temperatures, many families struggle with damp patches and black spots on walls, ceilings and glass. Bathrooms are especially prone to mould because of how much moisture builds up inside.
But experts say one indoor plant could make a real difference, not only by helping absorb moisture, but also by reducing foggy mirrors and condensation. Glass specialists say the arrival of autumn brings a fresh wave of damp problems. That’s because warm indoor air hitting cold windows creates condensation, which mould spores thrive on.
The team at Balustrade Superstore said this becomes a real issue in bathrooms, where constant moisture settles on surfaces like tiles, mirrors, and windows – often leading to black mould in corners, frames and even around sealants.
Mould doesn’t just look unpleasant. It can make windows less effective at keeping out the cold, and in some cases, cause damage to glass.
Experts also warn that it can affect breathing and trigger allergies, especially for those with asthma or lung conditions.
One natural way to reduce the risk is to keep a plant in the bathroom.
English Ivy, a popular indoor climbing plant, has been shown in studies to remove up to 94% of airborne mould particles in just 12 hours.
It helps by absorbing mould spores and lowering humidity levels, essentially acting like a natural air filter.
Another top choice is the Boston Fern. Unlike ivy, it doesn’t climb or spread, but it draws moisture from the air with its thick green leaves.
This can help reduce foggy mirrors and damp corners, which are the perfect environment for mould to grow.
A spokesperson for Balustrade Superstore said: “My wife always keeps a Boston Fern in our bathroom. It looks lovely but more importantly, it helps stop the mirror from misting up so quickly.
“We noticed fewer black spots around the window frame too, which shows how powerful these plants can be in keeping mould under control.”
They added: “Bathrooms are one of the toughest rooms to keep mould-free. Adding a plant like ivy or fern is a simple step, but it makes a difference.
“Of course, regular cleaning and ventilation are still important, but this natural option gives your glass and mirrors extra protection.”
To protect your windows through the colder months, homeowners are also advised to:
- Wipe down condensation after baths or showers
- Use extractor fans or open windows regularly
- Place plants in damp corners
- Check window seals and replace them if needed
