Use a container that is shallow and wide instead of tall and deep when planting lotus, according to the University of Florida. Fill a sandwich-sized plastic bag with sand and place it in the bottom of the container.
Mix the garden soil with 1/4 cup 10-10-10 fertilizer for every gallon of soil used. Fill the container two-thirds full of the soil/fertilizer mixture.
Dig a hole 2 inches deep and as wide as the root ball and place the lotus rhizome into the hole. Cover the hole with soil. Cover the soil with 2 inches of sand or gravel.
Lower the lotus into the pond so it is in water 6 inches deep. Once the lotus plant grows, place it in water 18 inches deep.
