Water Quality Analysis
Your Water Profile
Water hardness near Houston measures approximately 368ppm, classifying it as Extremely Hard.
⚠️ Hard Water Alert
High calcium and magnesium levels can accumulate in potting soil over time, causing brown leaf tips and nutrient lockout in sensitive species.
Recommended Actions
- • Use filtered or distilled water for Calathea, Ferns, and Orchids
- • Flush soil with distilled water monthly to prevent salt buildup
- • Consider an under-sink RO system for large collections
- • Repot annually with fresh soil for sensitive plants
Data source: Water hardness values are derived from monitoring station measurements published by the EPA Water Quality Portal (WQX) and USGS NWIS. These readings reflect source water conditions (rivers, wells, treatment intakes) near Houston and may differ from treated tap water delivered to your home. For exact tap water composition, check your local utility's Consumer Confidence Report (CCR). USDA hardiness zone data from phzmapi.org.
