Ah, the age-old question that haunts plant lovers everywhere: “Why Do My Houseplants Have Mold?”
Watering your plants is like giving them a hug, but too many hugs can be smothering.
Overwatering leads to persistent moisture, creating a breeding ground for mold.

Poor Water Drainage
Ever tried dancing in a puddle?
Neither have your plants.
Poor water drainage and dense soil can trap water, making it a haven for mold.
Choose well-draining soil and pots with drainage holes to avoid this soggy situation.
Insufficient Air Circulation
Plants need to breathe too!
Insufficient air circulation can cause stale, moist air to linger, inviting mold to settle in.
A simple fan or open window can be a breath of fresh air for your leafy friends.
Elevated Humidity Levels
Tropical plants may love humidity, but so does mold.
Elevated humidity levels can encourage mold growth, especially in tight spaces.
Consider a dehumidifier or placing plants in a well-ventilated area.
