There are several ways to protect your plants from the changing water level in swamps. You could use a small raft that holds planting containers. If tethered to a fixed object, the raft will float in place as the waters rise and the plants will stay above the water level. If nylon ropes were hung from the holes in the bottom of the container into the water they would act as wicks. The plants would be watered passively but automatically.
Another idea is to place the plants above the water level. For instance, you could place containers on stumps or in trees. You could build mounds of earth or debris that rise above the high water mark. When the rains come, the roots will still be in unsaturated soil.
