In my version, before humans stepped foot on the planet, the nature created 4 witches to maintain balance within the elements so that the mankind can live on the planet. Every witch would be responsible of their own elements, and would have the power to forge it, gain power from them. 1 witch was created for air, 1 for water, 1 for fire, and 1 witch for earth. As all witches lived within their elements, one day the earth witch mated with a human being and created an offspring. As a result, the witch was stripped away from her powers for punishment, but the offspring kept some of the magic. And therefore the witchcraft started among humans. The ones from the bloodline of the earth witch are simply called "Witch".

That's why witches are connected to earth, hence Bonnie said in 3x17 "Witches are connected to the earth, we can literally feel the nature" and then she made a flower grow fast.
