PURPOSE:To provide a method for sand culture designed to improve air permeability to the roots of a plant to be cultured in the sand in a pot to enable oxygen to be effectively replenished at all times. CONSTITUTION:In a sand culture for a plant A to be raised in sand 1, an air- permeable pipe 3 with fine mesh is embedded in the sand 1 in a pot 2 so as to open both ends 3a, 3b above the sand surface 1a to prevent the sand 1 from intruding into the pipe. |
