I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Your question is really many in one. If the pots around your plants have holes in the bottoms you can sink them into the pond and let them grow in the pots as the roots will grow out of the pots whether there is soil in the base of the pond or if it is a liner based pond. You can then easily move them or remove and replace them as needed.

Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
