White Fungus on Raised Bed Soil Surface

Annual white substance on raised bed soil, leaking through brick cracks. Asked if mold/fungus and what product to use.

Identification

Likely a harmless saprophytic fungus. Cultivating the surface periodically disrupts it.

Light raking/cultivation when it appears.
Broad-spectrum soil fungicide (check local garden center for approved products).
Mild bleach solution cleans brick faces.

No panic needed; it's cosmetic and not harming plants.
