Leaf Spot Fungus on Potted Impatiens: Watering Practices and Air Circulation

Diagnosis

Spotted yellow-green leaves with black centers = leaf spot fungus. The affected pot likely has less air circulation.

Management

• Water in morning only, targeting soil, not foliage.
• Water deeply twice in succession to saturate root zone, then let dry all day.
• Remove spotted leaves.
• Avoid wetting leaves—humidity worsens fungus.

With improved practices, plants can outgrow the problem unless humidity is very high.
