Thanks for the reply, I'll leave it to look after for itself then, it
seems they are quite capable of fending for themselves!!

Kind of depends what your pond is like. If allowed to fend for itself it
may not thrive if it can't jump the pot edge when the growing tip hits it.
If it does jump the pot edge it will populate your whole pond. Okay if
that's what you want, but all sorts of debris will eventually catch in it's
dying rhizomes and roots.

I put my lilies in plastic baskets lined with weed fabric, dirt, lily, and
more strips of weed fabric on top with river rock. Feed the lily tomato
spikes every now and again. This will make it easier to control the lily,
keep the pond bottom clean and when it comes time to divide, easy to remove
the lily. ~ jan
