The Correct Way to Introduce Water Lilies into Your Pond is to Allow Them to Get Used to Three Water Depth Levels.
It is wrong to immediately “position” them in a deep zone at once. To “introduce” them the correct way, position the water lily basket first on a shallow level and wait until the water lily has grown at least seven leaves. After observing so, remove the lily basket and position it at a deeper spot, and wait again for another set of seven leaves to emerge. Now, after there are already 14 water lily leaves, the lily basket can then be placed in its final depth.
