Saving a Struggling Nepenthes mira After Repotting

Rescuing a Repotted Nepenthes mira

A grower repotted their Nepenthes mira a month ago and is concerned about its decline. The plant receives distilled water and was previously on a windowsill with about 4 hours of light; it is now under grow lights.

Expert Diagnosis

Jeff Dallas notes that N. mira (similar to N. rajah) requires stable, elevated humidity. Large temperature swings from a sunny windowsill may be causing stress. He recommends moving the plant to a stable environment under grow lights only (no window) and increasing humidity. Ensure the pot is not sitting in water, as Nepenthes are not bog plants and are prone to root rot.

Action Plan

• Provide consistent temperatures and high humidity (e.g., a humidifier or terrarium with ventilation).
• Use only pure water (distilled, RO, or rainwater).
• Keep the soil moist but well-drained; do not let the pot sit in standing water.
• Allow time for recovery; new growth should appear if conditions improve.
