Venus Flytrap Traps Turning Black at Soil Contact: It's a Light Problem

A Dionaea 'Big Mouth' grown outdoors in Northern California had traps die wherever they touched the soil. The real issue: **only 4 hours of late-afternoon sun** – far too little.

What Healthy Flytraps Look Like

• Short, wide petioles (leaf bases)
• Erect, sturdy leaves
• Large traps with deep red interiors

The Fix

• **6+ hours of direct sun** – morning/midday is best.
• If impossible, supplement with a **40W cool-white compact fluorescent** 8 inches above plant, 12 hrs/day on a timer.
• Soil (50/50 peat/perlite) and water (distilled) are already correct.

Fall Note

With shortening days, the plant will soon enter dormancy. Artificial light can maintain growth through winter if desired.
