Fiddle Leaf Fig Brown Spots = Scale Insects, Not Overwatering

Those Brown Spots on Your Fiddle Leaf? It's Scale—Not Watering

Brown spots on new and old leaves of your outdoor Ficus lyrata in Phoenix: scale insects. The hard-shelled bumps suck sap, causing yellow/brown lesions. Overwatering isn't the issue—your heat-driven watering is likely appropriate.

Treatment (Persistent but Effective)

1. Q-tip + alcohol to remove visible hard shells.
2. Spray entire plant with alcohol solution (1:5 water + soap) to kill crawlers.
3. Repeat every other day for 2 weeks to catch hatching eggs.
4. Monitor weekly after.

Care Notes for Phoenix Outdoors

• Full sun is OK for acclimated fiddle leafs.
• Water deeply when top few inches dry—daily in 100°F+ is fine if draining.
• Fertilize monthly in growing season.
• Watch for spider mites in dry heat (fine webbing, stippling).

Why It Survived the Freeze

Fiddle leafs can resprout from the base after cold damage. Your hard prune stimulated vigorous regrowth—which attracted scale. Healthy, fast growth = pest magnet. Treat promptly, and it'll thrive.
