Thanks liquidsquid for that additional post from a person that actually has a similar pond.

I have recommended planters for those types of ponds. However, that was NOT based on personal expertise, but based on furthering the advice from OTHER Pond Boss members.

Do you have any good advice on planters in those types of garden ponds? For example, what is the best substrate in the planters, what types of plants have thrived, what types of plants struggled, etc.?
