Fabric pots, like the ones offered by 247Garden, are popular among gardeners because of their breathability, durability, and ability to promote healthier root systems. However, some gardeners encounter a common issue with these pots: a white, fuzzy substance appearing on the outside of the fabric. While it might look like mold at first glance, it's often just salt and mineral buildup. Let's explore this phenomenon in more detail and how you can effectively handle it.

What Is Salt Buildup?

Salt buildup on the exterior of fabric pots is a result of excess minerals and nutrients in your watering solution or fertilizer accumulating on the pot's surface. As water evaporates from the fabric, these minerals are left behind, forming a crusty or powdery layer. This is especially common in aeration pots like 247Garden's, which promote a high level of airflow and evaporation.

How to Tell the Difference Between Mold and Salt Buildup

Before taking action, it's important to identify whether the substance is mold or simply salt buildup. Here are a few ways to tell the difference:

  • Texture: Mold is usually soft, fuzzy, and can have a greenish or grayish color, while salt buildup tends to be more crystalline and rough.
  • Test with Hydrogen Peroxide: If you're unsure, you can lightly spray the affected area with a solution of hydrogen peroxide (H₂O₂). If it fizzes and the substance starts to dissolve, it's more likely to be mold.

Steps to Handle Salt Buildup on Fabric Pots

1. Improve Air Circulation

One of the best ways to prevent both salt buildup and mold growth is to ensure good air circulation around your fabric pots. Make sure your pots are elevated off the ground to allow airflow underneath. This helps reduce moisture accumulation, which can exacerbate both salt and mold issues.

2. Monitor Humidity Levels

High humidity can create a favorable environment for mold growth. Aim to keep the humidity levels below 50% in your growing area, especially if you're growing indoors or in a greenhouse. Consider using fans to keep the air moving and prevent stagnant moisture.

3. Flush the Soil

If you suspect that the buildup is primarily due to excess salts from fertilizers, it's a good idea to flush the soil with clean water. This process involves watering your plants thoroughly until water flows out of the bottom of the pot, helping to rinse out the accumulated salts from the soil.

4. Mycorrhizae and Beneficial Fungi

Sometimes, the white substance on your fabric pot may not be a problem at all. Beneficial fungi, like mycorrhizae, can appear as a white or fuzzy coating. Mycorrhizae are naturally occurring fungi that form a symbiotic relationship with your plant's roots, improving nutrient absorption and overall plant health. If you notice this, there's no need to worry—it's actually a sign that your plant's root system is thriving.
