That' why I prefer the branded products like whitetail clover. They are much more consistent than what i get at the feed store. I have had some success with certified seeds from the feed store but have had problems several times too. I have a friend who buys alot of seeds from his feed store and he had 100 pounds of certified ladino that produced nothing but turnips last year. He says he will lean toward the branded products more to from now on.
