In many European homes, damp and enclosed areas can foster mould growth, which often leads to allergies and other health issues. While most houseplants add humidity to indoor spaces, which can encourage mould, certain plants actually help to prevent mould build up naturally. Many of these plants, often originating from humid environments, can act as natural dehumidifiers by absorbing moisture from the air. Some even release antimicrobial and antifungal compounds, which may help reduce indoor mould.
Houseplants can counteract mould growth in several ways:
-
Absorbing Excess Moisture: Certain plants draw moisture from the air through their leaves, effectively reducing indoor humidity levels and making mould less likely to form.
-
Releasing Compounds that Inhibit Mould: Although uncommon, some plants release antimicrobial or antifungal compounds that may help prevent mould and mildew.
-
Enhancing Air Circulation: Plants with broad leaves help increase air circulation, which can discourage moisture buildup and reduce mould risk.
Here are five houseplants known to reduce indoor mould effectively:
1. Peace Lily (Spathiphyllum)
- Why It Works: Peace lilies are efficient at absorbing moisture, making them ideal for humid rooms like bathrooms and kitchens. They also emit natural compounds that may help limit mould growth.
- Care Tips: Peace lilies thrive in moderate, indirect light and should be watered weekly. Keep the soil slightly moist but avoid overwatering.
2. English Ivy (Hedera helix)
- Why It Works: English ivy is well-regarded for its air-purifying properties and can also absorb mould spores from the air. Its spreading vines absorb moisture and release oxygen, helping to reduce mould.
- Care Tips: English ivy grows well in bright, indirect light but can tolerate lower light. Maintain moist but well-drained soil, and trim regularly to keep it manageable indoors.
3. Boston Fern (Nephrolepis exaltata)
- Why It Works: Boston ferns thrive in humid conditions like bathrooms, where their fronds absorb moisture. They also release oxygen, contributing to a fresher environment.
- Care Tips: Boston ferns prefer indirect light and require high humidity, so misting regularly is beneficial. Keep the soil moist but avoid over-saturation.
4. Snake Plant (Sansevieria trifasciata)
- Why It Works: Known as mother-in-law’s tongue, snake plants release oxygen at night, making them suitable for bedrooms. They absorb moisture and filter out airborne toxins, helping to reduce mould spores.
- Care Tips: Snake plants are low-maintenance and adapt to low or bright indirect light. Allow the soil to dry between waterings, as they are drought-tolerant.
5. Aloe Vera
- Why It Works: Aloe vera is valued for its medicinal properties and is also effective at absorbing moisture. It releases antimicrobial compounds that may help inhibit mould growth, making it suitable for kitchens and bathrooms.
- Care Tips: Aloe vera needs bright, indirect sunlight and only occasional watering. Let the soil dry completely between waterings.
Maximizing Mould-Reducing Benefits with Houseplants
- Place in Humid Areas: Position these plants in damp-prone areas, such as bathrooms, kitchens, or laundry rooms, to help absorb moisture.
- Avoid Overwatering: Excessive moisture in the soil can create its own mold issues, so ensure each plant has well-draining soil and is watered appropriately.
- Wipe Down Leaves: Dust on leaves can block a plant’s ability to filter air effectively. Wipe them gently with a damp cloth every few weeks.
While these houseplants can help reduce moisture and discourage mold, they won’t remove existing mold completely. For significant mold issues, consider professional treatment along with good ventilation and anti-fungal solutions.
Adding these houseplants to your home can help create a fresher, healthier indoor environment. Whether you place a Peace Lily in the bathroom or a Snake Plant in the bedroom, these plants work naturally to improve air quality, absorb excess moisture, and reduce the likelihood of mould.
