Nepenthes in Rock Garden Yellowing: Root Contact with Standing Water Suspected

A 2-year-old Nepenthes on pumice rock (in 1-2" water tray) yellowed from bottom up. Grower noted volunteer sundews on the rock – a good sign.

Root Waterlogging Theory

• Nepenthes roots **asphyxiate in standing water** – they rot.
• Rock gardens: keep water **just deep enough to hydrate rock** (½-1").
• If roots hit free water, yellowing starts at base.

Repotting Benefit

• Annual repot aerates media, triggers growth spurts.
• This plant hasn't been repotted in 2 years.

Hermit Crab Red Herring

Nearby aquarium crab = zero impact.

Lower water level, consider repotting, monitor new growth.
