Can You Water Plants With Hot Water?

Question

The only hose tap in our garden is a hot water tap and the lowest temperature this can be set to is 40 degrees celsius. Will watering plants or hosing the lawn with 40 degree celsius (104 F) water do any harm to the plants or seeds? Thank You!

Answer 1

Some plants can handle it, some cannot. The best thing to do will be to put the hot water into a large container so that it can be left out to cool prior to watering. This will prevent any damage from water being too hot.
