10b. Potting and Propagation - Potting Specific Plants

Lilies are usually the main attraction in the pond and care should be taken in planting them. Lilies have a greedy root system that expands rapidly. Use the largest suitable container of 6 inches or more in depth. Plant hardy lily rhizomes with growing point or crown at soil level exposed to water. The rhizome should be on a slight angle and the crown should be up and as far away from the wall of the container as possible. The plant will grow in the direction the crown points and ample room for growth should be provided. This will also increase the time between re-plantings. If you intend on keeping the lily in deep water start it out in shallow water. As the plant becomes established move it a little deeper. Continue this process until the desired depth is attained. Planting a lily too deep too soon can stunt growth resulting in small leaves, poor flowering and even death.

Tropical lily tubers differ from hardy tubers in that the tuber is rounded and produces leaves and flowers from the center rather than an end. Tropical lilies should be planted in the middle of the container with the crown slightly exposed. Tropicals require water temperatures of 65 degrees or higher for vigorous growth. These lilies will not survive cold winters and should be protected from freezing in Zones 7 and higher.

Lotus supports a very large and fragile tuber that should be planted with the terminal growing tip extending just out of the soil. This fast growing beauty will rapidly outgrow its pot and requires more frequent repotting. Care must be taken not to damage the fleshy tubers of the delicate growing tips.

Pea gravel should be used to cover the surface of the soil to anchor the plant, keep soil in place and reduce cloudy water.

The best soil is heavy loam top soil. Never use manures, peats, and garden or potting mixtures in the planting process. These can kill fish and release nutrients into the water that will cause excess algae growth. Some mixtures are simply too light and will float. It is very important to plant soil tightly, tamping and packing it in all stages of planting.

All your pond plants should be fertilized at the initial planting, repottings and
monthly during the growing season.
