Arrowhead Plant Brown Spots: Watering Balance

Diagnosing Brown Spots

Large brown spots on variegated arrowhead (Syngonium) leaves, including new growth, indicate a moisture problem—either too wet or too dry. Yellow leaves and brown spots on new leaves suggest inconsistent watering or fungal issues from improper moisture.

Proper Watering Protocol

1. Pot with drainage hole + saucer (essential)
2. Water thoroughly until moisture reaches saucer
3. Empty saucer after 1 hour (turkey baster if needed)
4. Wait until soil dry 2-3 days before next watering
5. Gradually, roots expand and use water faster

Why This Works

Roots need oxygen between waterings. Constant moisture suffocates them. Thorough watering + complete drainage + drying period = healthy root respiration. The "finger test" and pot weight confirm readiness.

If Fungal/Bacterial

Light Lysol spray every 3 days for a month kills surface pathogens. But proper watering usually resolves it. Remove damaged leaves for appearance.
