Is the lawn fert going to have anything in it unsafe for use on edible plants? As I've been fertilizing the lawn this year, I've tossed a little in my wifes herb & vegetable garden. Obviously weed-n-feed type stuff would be bad, since many of the herbs & vegetables would be vulnerable to it. And the garden fert is generally lower N. But if I'm only using strait fert with no pesticide of any type, is there anything to worry about? I've got around 40# of Lesco lawn starter fert, I was thinking of using primarily in her garden.
