Repotting Nepenthes in Pure Sphagnum: Adding Drainage Without Root Damage

Improving Drainage for Nepenthes in Live Sphagnum

A grower (follow-up from previous advice) asked about 1:1:1 ratio of wetted sphagnum:perlite:orchid bark for repotting 10-month-old plants, and whether repotting again so soon is disruptive.

Expert Guidance

Jacob Farin: 1:1:1 is a good starting ratio. Wet sphagnum first to compact for accurate measurement. No magic formula—adjust for drainage.

Repotting Timing

If current soil is unhealthy (waterlogged), changing soil outweighs root disturbance risk. Better to repot than lose plant to bad conditions. Minimize root disruption but prioritize healthy media.
