If the water in the pond comes from a chlorinated source, allow it to set for a couple of days before adding plants. Inoculate the pond with a gallon of water from a natural pond to supply the necessary bacteria and other organisms that will aid in nutrient cycling. Plant into containers that are at least 6 in. Use regular garden soil, but after planting, cover the surface of the container with gravel to keep the soil contained. Set water lilies in the deeper water, and set bog plants on the ledge.
Hardy lilies can overwinter in the pond in cold climates.
Bog plants can be moved to deeper water for the winter to ensure their survival. Introduce fish after the plants have started to grow. Feed fish once a day, and only as much as they will consume in 5 minutes. Fish will cease feeding when the water turns cold. Fish can survive for weeks without supplemental food provided that the pond is teeming with life.
