I got my 100 gal. Rubbermaid container and have it set up to hold my plants until the pond is ready. Have a small pump and added a few goldfish.
Using a crate and some flat rocks, I put my 2 little lilies in about 6 inches lower than what they were previously (since the tank is deeper than the other container I had them in) and put my 4-leaf clovers in (they're a couple of inches deeper than the stem length). It's been amazing to watch how the stems are growing in order for the leaves to reach the surface! I never knew water plants did that: adjust to water depth. And the lilie pad-leaves are getting larger, too!
Another interesting thing I did was put some water lettuce in the 2 plant saucers I'm using as water bowls for the turtles. The water bowls have to be emptied, rinsed,& refilled anywhere from 2-4 times a day (that's why I wanted a pond for the turtles!). I added the plants yesterday, and either the turtles are scared of the plants and haven't even been in the bowls, or the water lettuce is filtering the water already! I added some water this afternoon, but didn't have to empty them.....
