Water Quality for Plants

Understanding Your Water

Louisiana's water averages 178ppm hardness throughout the state. This is considered Hard.

⚠️ Hard Water Alert

Hard water contains high levels of calcium and magnesium that can build up in soil and cause brown leaf tips on sensitive plants like Calathea, Spider Plants, and Ferns.

Solutions

• Use filtered or RO water for sensitive plants
• Let tap water sit 24-48 hours before using
• Flush soil monthly with distilled water
• Repot annually to refresh soil

Data source: Water hardness values are derived from monitoring station measurements published by the EPA Water Quality Portal (WQX) and USGS NWIS. These reflect source water conditions (rivers, wells, treatment intakes) 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).
