Venus Flytrap Traps Staying Closed? It's Normal Aging

Two VFTs (Red Dragon, green large-trap) in NE Illinois: full sun, distilled/rain water, 50/50 peat/perlite. Second season. Last year traps always open; this year mostly closed, some half-open, some never open. Photos attached.

Expert Explanation: Trap Mechanics and Lifespan

Steve explains: traps open/close via differential cell growth. After several cycles, they reach maximum growth and can no longer open/close. Older leaves (especially from previous season) naturally stay closed or "sprung." This is normal.

What to Watch

• New leaves from center should open, close when triggered.
• If new traps don't function, check for mineral poisoning (Miracle-Gro peat/perlite contains fertilizer).
• Your water is good; ensure soil components are fertilizer-free.
