Sarracenia Pitchers Browning at Base: Botrytis Rot

A grower loses Sarracenia (S. purpurea, 'J. Hindle', S. leucophylla) to a mysterious issue: pitchers look healthy but brown at the base (where they attach to rhizome), then detach with a twist. Rot spreads to rhizome, turning everything brown.

Diagnosis: Botrytis Mold

Jeff Dallas identifies this as botrytis, common in high humidity. It starts on dead foliage, spreads to rhizome. By the time pitchers drop, the rhizome is usually too far gone.

Prevention Is Key

• Grow outdoors in full sun (vegetable-garden sun).
• Use shallow trays of low-mineral water (rain/distilled).
• Remove dead leaves promptly.
• Use correct soil: peat + perlite/pumice/sand—never commercial potting soil.
• Shade weakens plants, increasing fungal susceptibility.

Early Treatment

• Non-copper fungicides if caught early.
• Sulfur-based fungicide as preventative spray.
• But nothing replaces good growing conditions.

Good Growing!
