Split Phalaenopsis Leaves: Humidity and Watering Consistency

Split Leaves = Low Humidity or Erratic Watering

Phalaenopsis leaves splitting at tips, with central lines predicting future splits, indicate chronic humidity deficit or irregular wet-dry cycles.

Fixes

• Humidity >50% (ideally 70%). Use trays, humidifiers, grouping.
• Regular watering: When media is barely dry—not bone dry, not constantly wet.
• Repot now into fresh bark mix (moss+bark suggests transition).
• After repotting: 2–3 weeks warm shade, then back to growing spot.

Fertilizer Note

"Oxygen Plus" alone isn't balanced nutrition. Add a complete orchid fertilizer.

Consistent moisture and humidity prevent splitting. New leaves will grow intact.
