Can tap water be used for Acer shrubs?

No, tap water cannot be used for Acer shrubs. The woody plants in question number among Maple family members and respond poorly to water high in calcium, chlorine and fluoride. They will handle tap water that receives a monthly teaspoon (4.93 milliliters) of vinegar per quart (liter) of water and that sits for a day to evaporate the above-mentioned contents.
