White Spots on Dragon Tree Soil: Mold Identification

Diagnosing the White Spots

White spots on soil can be several things:

• Fuzzy, attached = mold (most likely)
• Hard, rough = perlite (normal soil component)
• Soft, squishy balls = styrofoam beads (aeration additive)
• Off-white pellets = slow-release fertilizer
• Tiny mushrooms = fungal fruiting bodies

Your Case: Confirmed Mold

The follow-up photo confirmed surface mold from non-sterile potting soil. The grower used contaminated mix, and your watering provided the constant moisture mold needs.

Treatment Protocol

1. Scrape off all loose surface soil and mold
2. Expose root tops slightly
3. Move to warm, sunny, well-ventilated spot
4. Water only when top inch very dry
5. Remove any new mold immediately

Critical Care Corrections

• Uncover the window—curtains closed = insufficient light
• Check outer pot—no water collecting at bottom
• Identify plant correctly—photo suggests Yucca, not Dracaena

Mold dies in dry, warm, sunny conditions with good airflow. The contaminated soil was a nursery cost-cutting measure—your care can overcome it with proper conditions.
