Growing water lilies in a container water garden or large pond requires proper planting techniques. The first step is to choose a small container that measures 12-20 inches in diameter and 8-10 inches deep. This container will eventually be placed in your pond or tub. Cover the drainage hole with mesh or burlap to prevent soil from escaping.
Select a smaller pot if you’re working with a smaller tub instead of a larger pond because the plant will grow to the size of the container. Fill the pot two-thirds of the way with garden or aquatic gardening soil. Avoid lightweight potting mixes with perlite, vermiculite, or peat. The soil should be heavy enough to provide stability but light enough to promote a healthy root system.
Cover the rhizome against the pot’s side, with the growing tip pointing upward at a 45-degree angle towards the surface. Cover the root system with soil and add small rocks or gravel on top to stabilize the plant. When lowering the potted plant into the pond or tub, set it at an angle and let it gradually acclimate to the water temperature. Position the pot’s base 12-16 inches deep, allowing the leaves to float on the surface.
If your plant already has developed leaves, start by placing the container so that the leaves are just beneath the water’s surface, around 6-8 inches deep. Within a few days, the leaves should reach the surface, and the plant can be lowered to its final depth of 12-16 inches. Following these steps will help ensure a healthy and beautiful water lily in your pond or container water garden.
