The present invention provides a single crystal growth method capable of suppressing the recrystallization of the raw material gas subjected to sublimation on the surface of the raw material, and suppressing the generation of different polytypes in the crystal growing single crystal. The single crystal growth method is carried out in a crucible comprising an inner bottom for providing a raw material and a crystal mounting part facing the inner bottom. The method comprises in the following order: providing the raw material in the inner bottom; covering at least a part of a surface of the raw material with a metal carbide powder in a plan view from the crystal mounting part; and growing a single crystal disposed in the crystal mounting part by sublimating the raw material by heating.
