When the snow is not too deep to plow and the river don't rise, we usually have a good 3-4 months. A couple of years ago we had tons of rain in June…lost almost everything. By the time the gumbo (clay muck) dried out it was too late to plant again. This year I'm trying raised beds. I usually start as much as i can indoors and try to transplant or put seeds on the ground at the end of May.
