Multiple Phalaenopsis Issues: Wrinkled Leaves, Split Tips, Salt Toxicity, and Over-Treatment

One Grower, Many Phalaenopsis Problems—Root Causes Identified

A collection shows: wrinkled leaves (dehydration from root rot), split leaves (low humidity), line scars (early wrinkles), all despite new roots/spikes.

Root Causes

1. Wrinkled leaves: Roots rotted in pot—can't uptake water. Unpot; expect mushy roots.
2. Split leaves: Humidity <50% chronically. Raise humidity.
3. Coconut bark not pre-soaked: Salts in coconut media toxic to roots. Must soak 12 hrs multiple times before use.
4. Overuse of additives: Superthrive + Physan 20 every 10 days = too much. Max once/month.

Corrected Culture

• Water when media barely moist—not on a calendar.
• Bright shade, 1–2 hrs morning sun.
• 60–85°F, with 2–3 weeks of 55°F nights in fall for blooms.
• Repot in pre-soaked coconut or bark mix.

Simplify. Observe. The plants will respond.
