Water Types for Plants: Clean, Salt-Free Is Best

A student asks which water—tap, well, sparkling, mineral, tonic—is best for plants. The expert replies: any clean, pollutant-free, salt-free water works. Tap water with chlorine can build up chloride salts, inhibiting uptake. Well water high in aluminum or zinc may be toxic. No single source is superior if it's clean and adequate.
