Why do plants get white fungus?
White fuzzy mold on plants develops when naturally-occurring fungal spores germinate and grow. The white fungal growth—also called mycelium—appears in warm, damp conditions, especially plants that grow in poor light. Overwatering houseplants and keeping them in the shade can cause white mold to appear.
Is darker soil better?
The darker the color, the more decomposed the organic matter is—in other words, a greater percentage of organic matter has finished the process of breaking down into humus. Also, very dark soils generally contain sodium, as sodium causes organic matter and humus to disperse more evenly throughout the soil.
