Brown Spots on pink princess — Fix & Prevention

What's Happening

Extrafloral Nectaries (EFNs). These are natural glandular structures on the leaves and petioles that secrete sugary nectar. On Pink Princess, they often appear as small, circular pink or brown spots, sometimes with a tiny drop of sticky sap.

How to Fix It

1
Check for stickiness: If the spots are sticky to the touch and roughly circular, they are likely EFNs.
2
No treatment needed: EFNs are a sign of a healthy, active plant and are a natural defense mechanism.
3
Wipe with damp cloth: If the sticky sap attracts dust or mold, gently wipe the leaves with distilled water.
4
Differentiate from Rust: Unlike rust fungus, EFNs do not rub off as orange powder and typically don't have a yellow halo.

How to Prevent It

Maintain stable environmental conditions. High light and high humidity can increase nectary activity, but as they are harmless, no prevention is strictly necessary.
