Orange Leaves on Nepenthes truncata: Normal Aging or Problem?

A three-month-old Nepenthes truncata showed one fully orange leaf and orange tips on two others. Conditions: bright light + 2 hours direct sun, 60W fluorescent supplement, distilled water, 20–50% humidity, soil kept moist.

Diagnosis

This is almost certainly normal leaf senescence. N. truncata is exceptionally tolerant of low humidity and household conditions. Older leaves naturally yellow/orange and die as the plant produces new growth.

When to Worry

• New growth shows discoloration, deformation, or blackening.
• Multiple leaves decline simultaneously.
• Pitchers fail to form on new leaves despite good light.

Action

1. Send a photo for confirmation (email to Sarracenia Northwest).
2. Continue current care—it's working.
3. Trim fully dead leaves at the base; leave green tissue.

N. truncata is a rugged, rewarding species. Orange lower leaves are just part of its growth cycle.
