Fungal Growth in Dracaena Soil: Mushrooms and Finger-Like Projections

A 7-foot Dracaena in a 17-inch pot summered outdoors in shade, developed brown mushrooms in soil. Now indoors, yellow finger-like fungal projections appear with mildew odor. Watered every 4–5 days in a foyer with indirect light.

Explanation

Outdoor exposure introduced fungal spores. The growths are harmless unless you have mold allergies.

Management

• Remove growths by digging out roots and tops.
• Remove loose surface soil not in contact with roots to reduce spores and speed drying.
• Keep soil as dry as possible; most Dracaenas can go a week+ between waterings.
• Fungi need damp conditions; dryness suppresses them.
