It is not just important to know about the frequency of water but the quality of the water itself.  Let’s discuss what type of water is perfect for houseplants.

Types of water for indoor Plant

  • Tap Water
  • Hard Water

Tap Water

A colossal number of people feel comfortable using tap water for houseplants because it is easily available all the time when we need it. The quality of tap water depends on your residential area. Tap water can be divided into two categories hard water and soft water depending on minerals. Tap water contains

  • Fluoride
  • Heavy Metals
  • High sodium level

Palms, spider plants, dracaenas, and Calathea are pickier to fluoride so, be careful about these plants.

Hard Water

Hard water includes calcium, magnesium, carbonates, bicarbonates, and sulfites. Calcium and magnesium salts can accumulate in the soil as a result of watering the plants with hard water. High alkalinity in hard water can kill a few plant species. If you water your green friend with hard water, it’s very important to flush out the salty soil every 2-3 months through rainwater, filtered, or distilled water. If you notice brown spots on the surface of the leaves then stop using hard water.

Soft water contains potassium chloride and sodium ions. Watering your plant with soft water is very unhealthy and toxic because it completely builds up sodium ions on the surface of the soil.
