5 Houseplants That Help Fight Mold

In many American homes, damp, enclosed spaces can lead to mold growth, often triggering allergies and other health concerns. While houseplants generally increase humidity, which can create a mold-friendly environment, certain plants actually help combat indoor mold naturally. These plants, often tropical in origin, not only add fresh greenery to your living spaces but also act as natural dehumidifiers by absorbing ambient moisture. Some even release antimicrobial and antifungal compounds, helping to naturally inhibit mold formation.

Houseplants can reduce mold growth in a few key ways:

  • Absorbing Excess Moisture: Some plants absorb moisture from the air through their leaves, acting as natural dehumidifiers. By lowering humidity levels, they create a less favorable environment for mold spores.

  • Releasing Mold-Inhibiting Compounds: Although rare, some plants emit antimicrobial or antifungal compounds that can inhibit mold and mildew growth on surfaces.

  • Improving Air Circulation: Plants with broad leaves encourage air circulation, which prevents moisture from settling, reducing mold risk.

Here are five houseplants known for their effectiveness at reducing mold:

1. Peace Lily (Spathiphyllum)

  • Why It Works: Peace lilies excel at drawing moisture from the air, making them especially effective in humid areas like bathrooms and kitchens. Their leaves also release natural compounds that may reduce mold growth.
  • Care Tips: Peace lilies thrive in moderate, indirect light and need weekly watering. Keep the soil slightly moist but avoid waterlogging.

2. English Ivy (Hedera helix)

  • Why It Works: Known for its air-purifying properties, English ivy also absorbs airborne mold spores. Its vines spread across surfaces, helping to absorb moisture and release oxygen, which may discourage mold.
  • Care Tips: English ivy does well in bright, indirect light but can handle low light. Keep soil moist but well-drained, and trim to prevent excessive spread indoors.

3. Boston Fern (Nephrolepis exaltata)

  • Why It Works: Boston ferns thrive in humid areas, such as bathrooms, where their feathery fronds absorb moisture, releasing oxygen that purifies the air.
  • Care Tips: Boston ferns prefer indirect light and high humidity, so regular misting is beneficial. Water frequently to keep the soil moist without over-saturating.

4. Snake Plant (Sansevieria trifasciata)

  • Why It Works: Also known as mother-in-law’s tongue, snake plants release oxygen at night, making them ideal for bedrooms. They absorb moisture and filter out airborne toxins, potentially reducing mold spores.
  • Care Tips: Snake plants are low-maintenance, tolerating low to bright indirect light. Water sparingly, allowing the soil to dry between waterings.

5. Aloe Vera

  • Why It Works: Aloe vera is widely recognized for its medicinal uses and is also effective at absorbing moisture. It releases antimicrobial compounds that can inhibit mold, making it ideal for kitchens and bathrooms.
  • Care Tips: Aloe vera needs bright, indirect sunlight and occasional watering. Allow the soil to dry completely between waterings.

Maximizing Mould-Reducing Benefits with Houseplants

  • Place in High-Humidity Areas: Position these plants in areas like bathrooms, kitchens, or laundry rooms to help absorb moisture.
  • Avoid Overwatering: Excess moisture in soil can lead to mold, so make sure each plant has proper drainage and is watered according to its needs.
  • Dust Leaves Regularly: Dust can hinder a plant’s ability to filter air. Wipe leaves gently with a damp cloth every few weeks.

It’s important to note that houseplants won’t remove existing mold entirely. For significant mold issues, professional treatment is recommended, along with proper ventilation and antifungal measures.

By integrating these houseplants into your home, you can create a fresher, healthier indoor environment. Whether it’s a Peace Lily in the bathroom or a Snake Plant in the bedroom, these plants help create cleaner, more breathable spaces while absorbing excess moisture and naturally discouraging mold growth.
