Repotting Darlingtonia: Timing, Media, and Lava Rock Alternatives

If It's Happy, Don't Touch It

Darlingtonia is far more sensitive to root disturbance than Sarracenia. If your plant is thriving in its current mix, leave it alone until spring.

Best Repotting Window

• Warm climates (CA, South): Early March
• Cooler climates: April, as dormancy breaks

Repotting at emergence lets the plant recover with the growing season ahead.

Media Options (Lava Rock Not Essential)

• Ideal: Live sphagnum moss
• Excellent: Equal parts peat, perlite, small orchid bark
• Good: Peat + perlite + pumice
• Goal: Moisture-retentive but well-aerated (like Nepenthes mix)

Decorative rock suppliers carry small lava rock; grill lava rock works but is coarse. Pumice is a great substitute.

Superthrive

Yes — soak roots 15 minutes during repotting. Significantly reduces transplant shock.
