Do plants grow better in Salt water or tap water?... Please tell me which one....and what are your sources if anywebsites...please please leave them with your answer!!!

Answer 1

Isn't the point of the science project that you find this out by experimentation?

I can't imagine it would grow better in salinated water. Because salt is so often use to extract moisture from things. It might affect things like tomatoes, which might make them sweeter/saltier/etc., though.

Answer 2

tap water. There are plants that naturally can grow in salty water.

The cells of the plants explode or die of the high pH of the salt.

Could ask a nursery worker.

Answer 3

apparently salt water kills the plant:
