Nepenthes ventricosa: Brown Growing Tip After Repotting—Humidity Shock, Not Root Rot

A brown, drying growing tip on a recently repotted N. ventricosa in sphagnum moss is likely humidity shock—not root rot. The stem looks healthy; roots are probably fine.

Why It Happens

• Repotting + increased light + lower humidity = transpiration stress.
• New growth is most vulnerable; older leaves acclimate better.
• Sphagnum from Home Depot (Better-Gro) is fine if it drains well.

What to Do

1. Remove the ceramic cache pot—prevents waterlogging.
2. Keep soil evenly moist, not soggy.
3. Give it 6–12 months to fully acclimate.
4. No need to repot again unless new growth dies back.

Root Rot Signs (For Reference)

• Blackening traveling up stem from base.
• Collapse of multiple leaves.
• Foul smell from soil.

Your plant is adjusting. Patience and stable conditions will bring healthy new pitchers.
