What Is White Mold?

White mold is not a specific strain of mold. Three species count as white mold, and they are Aspergillus, Cladosporium, and Penicillium.

Why Does White Mold Grow On Plants?

White mold growth is usually harmless. The development is due to a saprophytic fungus that feeds on decomposing organic matter.

1. Poor lighting

Mold thrives in dark and damp environments; hence, little sunlight would invite mold spores to settle on your plants. Not to mention that your plants also have moisture and food for them to grow.

Moreover, it is unhealthy for plants to go without sufficient sunlight. With poor lighting conditions, you are inviting mold and making your plant sick.

Moisture and lack of ventilation go together when it comes to mold growth on indoor plants. 

 

3. Lack of ventilation

Tips to prevent white mold growth on plants

Like with everything else, mold prevention is better than dealing with mold growth itself. Here are some ways you can prevent white mold growth on your plants:

 

Water appropriately

Overwatering invites mold growth. Meanwhile, underwatering may ruin your plants because they do not get enough nourishment.

To avoid haphazard watering, check your plant’s soil before watering. To check, poke the ground and see if the water is damp.

If it is damp, it does not require any more water. If the topsoil is dry, then feel free to water your plant. 

 

Bottom feeding

Setting a bowl of water underneath the plants will keep its top surface dry, which would prevent mold growth in that area. Bottom feeding is also better for plants because it inspires deep root growth

 

Clean the topsoil

Since mold feeds on decomposing organic matter, you have to remove leaves on the soil to prevent mold growth. Eliminating debris and dead leaves is especially important among large and bushy plants.
