Majesty Palm Decline: Scale, Starvation & Wrong Light—Rescue Plan

Majesty Palm (Ravenea) Yellowing/Browning: It's Not Just One Thing

Your year-old Ravenea rivularis/glauca shows bottom-up yellowing/browning + brown bumps = scale insects + nutritional starvation + insufficient light. The "houseplant" tag is misleading—this palm needs full sun, heat, humidity, and heavy feeding.

Immediate: Scale Eradication

• Don't use pyrethrin sprays (Schultz)—they don't kill scale and harm beneficials.
• Use horticultural oil (ultra-refined/superior) to suffocate all stages. Spray to dripping, repeat in 7 days.
• Better: Ladybugs. Move plant outdoors, release ladybugs—they devour scale in days. No chemicals.

Long-Term: Fix the Culture

• Light: Full sun outdoors summer. Brightest window winter.
• Fertilizer: Palm-specific 4-1-6-2 + Mg, Mn, Fe, Zn, Cu, B. Monthly growing season.
• Soil: Palm mix (not Miracle-Gro). Fast-draining, slightly acidic.
• Water: Keep evenly moist—never bone dry, never soggy.
• Winter: Cool (55–65°F), bright, humid. Hard indoors.

Species ID Matters

R. rivularis (40 ft) vs. R. glauca (20 ft). Fast growth = rivularis. Both need intense conditions. Indoors long-term? Poor prognosis. Best as seasonal patio plant.

Bottom Line

Treat scale with oil or ladybugs. Feed correctly. Give max light. Accept it may never look perfect indoors—it's a tropical palm sold as a houseplant.
