planting veggies on land that was flooded
Does anybody know about this? We live on the river and our yard flooded during Katrina. I planted tomatoes and a few herbs in a raised bed last year and they did OK, and we didn't get sick. Then I read what "ima diggin" wrote and now I am concerned about planting my little salad garden this year! In another post he/she wrote:
"Also, even if you don't think you'll ever flood, put your veggies, herbs and fruit trees in window boxes or planters so they can be moved before high water or floods. Once they are contaminated by flood waters, they can't be consumed. If the soil has ever been under flood water, it's best to consider it unfit for food production (think contaminated lettuce in California)."
How long would the land be contaminated and is there something I can do to my garden plot soil to make it safer? Should I just consider it OK since it was OK last year? Ima diggin are you out there? Anybody else know? Thanks!
