I just ran across this and found it interesting. Here's the quote that caught my attention regarding use of clay soil (IOW, Kitty litter or any soil containing clay) with water lilies --

"The recommendation for using soil that contains clay comes from the fact that clay particles serve as a colloidal sponge, adsorbing and holding onto dissolved nutrients until the lily roots access them. In extremely sandy soil, added nutrients quickly dissolve and migrate out of the sand into the water. There they only feed algae, not the waterlily. Clay in soil helps to slow the loss of fertilizer to the water, keeping it in the soil pot where the roots access it."

And here's the link.

Mine are in kitty litter I tried a few free floating, they did lousy, found a free one just recently, it had 4 leaves on it. It is being planted now.

Plain non clumping kitty litter works great. But I use safety absorbent (Safe T Sorb) from tractor supply cause it is a bigger bag and cheaper.

NIce little snippet of info. to add to that or rephase, clay has a higher CEC (cation exchange capacity) than sand or gravel which are inert.
