Fabric pots can sometimes develop mold growth on the outside due to a few different reasons:

  1. Moisture: Since fabric pots are designed to allow water to pass through the material, it's possible that they may hold onto excess moisture. This can create a damp environment that is conducive to mold growth.
  2. Humidity: If the air in the area where the fabric pot is located is humid, this can also encourage mold growth. The moisture in the air can cling to the fabric and provide a moist environment for mold spores to grow.
  3. Organic matter: If the fabric pot has been filled with soil or compost that contains organic matter, such as leaves or plant debris, this can also provide a food source for mold to grow on.
  4. Main reason not enough sunlight or plants too crowded next to each other. Not enough clean oxygen for good air circulation.
  5. Bad soil.
  6. Weak sunlight.
  7. Wet pot under cloudy chill sky.

The Good News! We can connect with the plant!

Even with mold and mildew on a grow bag, it's not like the end of life. As long as the plant is still healthy, you still have plenty of time to treat it. Just make sure the pot gets enough sunlight and also give it some good air culation. Just imagine you are the plant. Where do you like yourself to be most of the time?

How to prevent mold and mildew from growing outside grow bag?

Mold and mildew can be common issues when growing plants in grow bags, especially in humid or wet environments. Here are some ways to prevent mold and mildew from growing outside of grow bags:

  1. Good Drainage: Make sure your grow bags have adequate drainage holes and are placed on a well-draining surface. This will prevent water from pooling in the grow bag, which can create a damp environment conducive to mold and mildew growth.
  2. Air Circulation: Providing good air circulation around the grow bags can help prevent mold and mildew growth. Consider placing fans near the plants to promote air movement or place grow bags in a location with good airflow.
  3. Proper Watering: Avoid overwatering your plants as this can create a moist environment that promotes mold and mildew growth. Water your plants when the soil is dry to the touch and consider using a watering schedule to ensure consistency.
  4. Use a Fungicide: Apply a fungicide to the outside of the grow bag to prevent mold and mildew growth. Look for a product that is specifically labeled for use on grow bags and follow the manufacturer's instructions.
  5. Clean Regularly: Clean the outside of the grow bags regularly with a solution of water and vinegar or a mild soap. This will help remove any potential sources of mold and mildew and prevent them from taking hold.
  6. Warm and bright sunlight.
  7. Elevate the fabric pot. Let water drain away. But don't ever forget to give it water. Check for leaf color to ensure the plant is as green as possible when it's suppose to be green. Treat nature with care and you will get beautiful nature as a gift.

By following these tips, you can help prevent mold and mildew from growing outside your grow bags and keep your plants healthy and thriving.
