Your state's water quality is suitable for most houseplants without special treatment.

Solutions

• Tap water is generally safe for most plants
• Let water reach room temperature before using
• Flush soil quarterly to prevent salt buildup

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).
