Pool Designs
If typical pool construction does not appeal to you, try one of these pool designs instead. Some of these ideas may work better than others, but all can create a wonderful addition to your water lily garden.
Puddling with Clay
“Puddling with Clay” was one of the original and pioneering methods for pool construction, however it is no longer considered an effective method. The problem with clay pools is that they leak, and require a constant stream of water to replace the water loss. The colder water also makes plant growth difficult. Clay will attract crayfish, which can tunnel into the clay, further destroying your pond. This type of pond should be avoided, unless you choose to create a smaller version, a dew pond, which will eventually sustain itself with water.
Puddling with Concrete:
Puddling with Clay may not work, but doing it with concrete can have wonderful results. Almost half of the water lily ponds constructed used this method. Puddling with concrete is cheaper and less complicated. Although not as strong as a formed concrete pool, it is stable enough. This method uses less concrete and can be formed to fit any shape.
Puddling with concrete is similar to a formed concrete pool. You may need to dig to the same depth, although you can possible get away with2 or three inches less of tamped cinder. The difference is it does not need to have formed sides, but do make sure to place the sides much like the floor. Reinforcing your pool is crucial, especially the corners, with steel to keep it sturdy!
Like the formed pool, make sure it sets for 48 hours, and then keep it moist for ten days to make sure it is ready.
