Technical detail:

You can't get rid of the salt in beach sand by simply washing it. During its 
long immersion in salt water, sodium ions have gradually penentrated the 
crystal lattice of the minerals comprising the sand. Removed to a freshwater 
environment (i.e. in a flowerpot), saltwater beach sand then gradually releases 
this sodium over a very long period of time.

Listen to what Jane says, people, heed her words.
