2009 out door swamp/wet land grow (plans) need help

Alright well this will be my first out door swampwetland grow. where i am growing you can not dig a few inches into the soil with out seeing water. but its not a water bed its just really wet soil. My plan is to grow them 1.5 to 2 feet tall in my yard. then put them into 7 gallon buckets with no bottoms, stuck 2 inches into the wet ground.I will use ferts everytime i water it (twice a week).

what is a good soil mix for doing what im doing?

and if any one has any other ideas of tip/help that would be awsome.
