White Fuzzy Growth on Ficus Soil: Mealybugs, Fungus, or Mineral Deposits?

Three Possibilities

1. Mealybugs: Usually on leaves/stems, not soil. If it moves, it's mealybugs.
2. Benign Fungus: Common on soil surface; not an emergency.
3. Mineral/Salt Crust: From hard water or fertilizer (e.g., Baby Bio). Not fuzzy, but possible.

Recommendations

• Switch to organic fertilizer (fish emulsion) to avoid salt buildup.
• If growth doesn't move, it's likely harmless fungus or minerals—scrape off.
