Growing in the Swamp

I am wondering what are some different ways to grow right in a Swamp. I have built little platforms in the past and grew out of 5 gallon buckets. There was a lot of thrashing through the muck to feed them. I have herd of filling half a bucket with large gravel and drilling holes in the bottom and setting it right on the wet marsh soil. I am not sure how that works, does the gravel act as a wick or do the roots grow down in the gravel. That method seems like it would not leave much room for root due to part of the bucket being to wet/underwater
Has anyone tried this method or has any one grown in a marsh before.
Any other ways of dealing with very wet areas, buckets designs or right in the ground either way. I am just looking for ideas.
I would really like to find a good way for this to work. I live in a area that has crazy tree coverage with not so powerful sun. The swamps are every where and mostly open. I am just looking at going in low lining areas not right in the water. Areas that might be under water for the spring melt and dry up soon after but still have the hole in the canopy that lets sun in. Something like the south banks of a swamp, no big trees blocking the sun not in the water but still really wet.

Short term,..piles of dirt three foot high, flat tops and make a bunch of them !!

Long term,...Build a stone wall two maybe three ft. high and three stones wide in the shape of a square or circle or something,..fill it with dirt !!

You don`t have to cut down trees but you sure could remove alot of branches !!

Just a couple thoughts !!

I've seen people put them in a tree u can always do a couple that way

wood planks?

Lava rocks or gravel have alot of air in them to allow roots to breath. I would only do the first 2-4" of the bucket and use a promix or light soil. Mold resistant strain tho major.Good luck

I took fence posts and cut them up then built like a log cabbin and put steaks through the holes in the fence posts lining them up and staggering as I went. Ended up being a 5x5 square which I then made a huge tin rectangular pot to cover the top of it. I took a thick rope and cut it in half then drilled four hole in the corners of my box. And put each end of these two ropes I had in the holes and suspended the, down into the water. I frayed then ends of the ropes also so now I have a platform with four ropes hanging into the water... Through the process of wicking the ropes would pull water up into the pot. I threw six plants in this three on each side strattling the ropes and lst the two outside ones away from the structure to give everyone more light. Filled it with the best compost I could get my hands on.... You still have to go out to feed once and a while, you can cut down by using organic slow releasing nutrition. The ropes just help keep water up in the system or to transport it out should there be a good rain. I found all the ambient moisture was good and bad, good in that on those really hot days the plants could absorb some water... Bad when you start to budd perfect condition for budd rott... Also make sure you don't drop anything into the mucky muck you will never see it again hahha

Edit: I used pt fence post, I would recommend the same if you want the thing to. Last more than two seasons. Plus the pt splinters are orgasmic
