If you’re looking for alternative ways to get rid of mold in your home, you’ll be surprised to know there are certain houseplants that will help to prevent mold and mildew from forming.

While we often use houseplants to decorate our homes, plants are also known to alleviate indoor pollutants. Mold is one of the most common indoor pollutants, thriving in areas of the home where there are high levels of humidity and moisture. What’s more, if mold isn’t dealt with, spores in the air can cause serious health problems such as allergies, asthma and other respiratory illnesses. 

According to gardening experts, houseplants are great natural solutions to alleviate the problem and bring moisture levels down in the air. “Mold in the home is caused by excess humidity. Warm rooms, like bathrooms and kitchens are at particular risk,” advises Chris Bonnett from (opens in new tab)GardeningExpress.co.uk (opens in new tab). “Using plants to help keep mold at bay is a practical and natural way to control humidity and moisture in your home. How good a plant is at reducing humidity is all to do with its ability to absorb dew, fog and other moisture through its leaves. This moisture then moves down to its roots. You will notice an improvement – and you’ll have beautiful plants to enjoy too.”

In addition, if you didn’t have one of the best dehumidifiers at hand, the houseplant is a more affordable option. So if you want to keep mold at bay, without using harsh chemicals, check out these handy houseplants. 

1. Orchids

Orchids are one of the most common houseplants, and great at brightening up our home décor. But these vibrant florals are also good for absorbing moisture, and keeping down moisture levels. “Orchids also help reduce humidity in the home. They get all their nutrients and moisture from the air around them,” agrees Chris Bonnett from (opens in new tab)GardeningExpress.co.uk (opens in new tab). Since they thrive in sunlight, it’s best to place them on a windowsill in the bathroom or kitchen, and avoid watering it too much.

With their beautiful, white flowers, Peace Lilies are also known to absorb moisture through its leaves. This popular houseplant loves the shade and thrives in high humidity, making it the ideal choice for areas prone to mold. “It absorbs moisture through the air through its leaves and doesn’t need direct sunlight to thrive,” agrees Bonnett.  

In addition, Peace Lilies are also great for those that suffer from allergies or asthma. However, this plant can be toxic to pets so be sure to keep them away. Here are some other plants that are poisonous to cats and dogs if you have pets.   

3. Snake plants

Snake plants, also known as mother-in-law’s tongue, are another popular houseplant for removing excess moisture in the home. These hardy plants are great for condensation, and grow best in bright light and warm temperatures, such as the bathroom. 

Best of all, snake plants are low-maintenance, and only need watering every two weeks. In addition, these adaptable houseplants are known for filtering common household toxins, which is handy if you don’t have one of the best air purifiers.  

4. Palms

Not only do these exotic, lush leaves make a great decor feature to any room, but palms are also ideal for banishing mold. Their large leaves can absorb moisture in the air, and a NASA study also claims palms can filter large amounts of formaldehyde and other common pollutants. “Palms are a great choice to help control humidity and keep mould at bay, absorbing moisture through their leaves,” says Bonnett. “Varieties to look out for include Areca palms, bamboo palms, the lady palm, dwarf date palm and reed palm.” 

5. Boston Fern

This evergreen houseplant thrives in high-humidity areas, making it perfect for preventing mold and mildew. Ideal for the bathroom, the Boston Fern grows well in low levels of light. So be sure to keep them in shady spots, or near dark corners where mold is likely to form. “The Boston Fern thrives in moist climates and will naturally absorb the air moisture and balance out humidity levels in your home,” states Bonnett, “All it needs to survive is indirect sunlight and regular watering.” Ferns also make great looking houseplants, so it’s a win-win!
