if you plant in the river or creek bottoms the soil will probably be there and so is the water...i am legal so i can plant straight out in the garden.. i love my new found freedom.... i live in the mountains and the growing season here is very short..then you have to worry about deer. not to mention other people who like pot like me! oh did i forget to mention the impact it will have on our forest service lands and our ability to use them freely, if there pot gardens in on their lands it give them more of a reason to take that privilage
