Fill a 32-qt. bucket nearly to the top with pond soil, which is available from most gardening centers.
Set the lotus flower rhizome into the soil.
Cover the lotus flower rhizome shallowly with pond soil.
Cover the pond soil with 1 inch of washed gravel.
Place a rock over the gravel to keep the rhizome from floating up. The flower will grow around the rock.
Lower the bucket into your pond so that it is 4 inches below the water surface. Place bricks or blocks at the bottom of the pond if it is too deep. The lotus will grow on its own after this.
