I spent an hour combing through the garden this past weekend pulling out the stealth pigweeds! That weed cost me the entire season. It was so bad last year that I took this year off and went with a till and kill approach. I tilled the garden in the spring, then watered and tended. When the pigweed came up, it was time to till again. I did this all summer to try to get the seed numbers down. Hopefully it worked. I don't think I could survive another year without a garden!
