Well not really, that was a crappy pic.
Anyways all my plants are directly planted in the substrate. When I dug the pond I planned on having several lilly pockets dug and a couple of areas for marginals. Just lay out where you want plants or even large character boulders to be. Dig a depression, maybe 3-6" deep and a foot or so around prior to underlayment and liner install. I made the lilly pockets a little wider since they were situated on the bottom of the pond as opposed to a shelf or other shallow area. this gives them plenty of room to spread out. Remove plant from nursery container and wash off all soil. Place it in the depression w/some gravel when backfill the pond with gravel. Make sure the crown is at the same level as it was growing in the previous container.
