I fertilize my waterlilies with the Laguna year long fertilizer spikes - it only has to be done once and it doesn't hurt my fish or the birds, squirrels or anything else that drinks from my pond.

I have never tried the propogation method you mentioned - however, early each spring, the waterlilies are pulled from the bottom of the pond and divided with a sharp knife. Make sure you have a growth point in each division and before you know it, you will have more waterlilies than you'll know what to do with.
