Venus Flytraps Dying in Spring-Fed Bog? Check Water Minerals

VFTs in a natural spring-fed peat bog (8 hrs sun, Zone 6b) turning black, no new growth. Other CPs doing well. Spring water tested: not high but not low minerals. RO filter purchased; plans to top-water to leach soil. Will this help?

Diagnosis: VFTs Are Mineral Canaries

Jeff Dallas confirms VFTs are among the most sensitive to hard water, especially all-red forms. Symptoms match hard water degradation. Spring water in limestone areas (e.g., Ozarks) is very hard (Mg, Ca are toxic; Fe less so). Water must be <50 ppm. Their well water is 120–130 ppm—too hard without treatment.

Solution

• Use RO water + rainwater if possible.
• VFTs go first; Sarracenia will follow if water isn't fixed.
• Top-watering with RO helps leach minerals.

Good Growing!
