Tap Water

Tap Water

Tap water may sometimes contain too much calcium, and therefore be too alkaline, for watering plants such as orchids or cacti.

It is very easy to remedy: mix 1 teaspoon (= 5 ml) of white vinegar (8 %) with 1 gallon of water (5 l).

The exact proportions are 1 ml vinegar per liter of water.

If you are unsure whether your water is too alkaline or not, you can test it with a pH test or litmus paper.
