Why Rainwater Can Be Better For Some Plants Than Tap Water

Mains tap water undergoes extensive chemical treatment to make it safe for human consumption. Municipal suppliers regularly add chlorine, chloramines and fluoride to disinfect supply lines and support public health. While these additives are completely safe for people to drink, they can prove troublesome for delicate houseplants and garden crops. Chlorine and fluoride accumulate inside potting soil over time, often causing burnt leaf tips, brown margins and spotty foliage on sensitive species like peace lilies and ferns. Natural rainwater provides pure, chemical-free hydration that keeps leaves looking green and vibrant.
