PURPOSE: An initial growth promoting and controlling method of plants using magnetic field is provided to reduce the generation rate of side effects on the human body compare to a conventional growth promoting method using chemicals. CONSTITUTION: An initial growth promoting and controlling method of plants using magnetic field comprises the following steps: preparing more than two petri dishes, tap water, cotton sheets, magnet laminated paper, more than 4 sheets of white paper, and a thermometer; layering the white paper sheets; soaking the cotton sheets with water after inserting into the petri dishes; installing the thermometer around the petri dishes; sowing garden balsam seeds in the petri dishes; mounting one of the petri dish over the magnet laminated paper, and remaining the other one as a control group; and covering lids over the petri dishes for maintaining the uniform temperature and the humidity.
