Ming Aralia Rust Spots: Water Quality and Soil Moisture

A 3-year-old Ming aralia gets rust spots on leaves, then they drop and regrow cyclically. Gets lots of light and water.

Expert Analysis (Will Creed)

• Few spots = normal.
• Extensive spots: Check water quality—hard or softened tap water causes this. Use distilled/filtered.
• Soil moisture: Top inch should dry between thorough waterings. Constant moisture → symptoms → root rot.
• Recent repotting? Can keep soil too wet too long.

Correct water and soil moisture to stop cycle.
