I have never used biodegradable pots in the pond. They could work okay. When I pot lilies I first get them growing in shallow water then as leaves appear and it looks like the lily will continue growing I move the pot deeper as more leaves appear. If you use the decomposable pots and lilies are growing I would make a depression in the pond bottom so the top of the pot is close to the sediment surface. Hybrid lilies will spread fairly slowly if growing in compacted pond clay which is pro and con depending on ones goals.
