    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.

    There should be nothing to worry about as you described it. Doesn't mean it is ideal for your garden, but I do the same thing.

    Milorganite used to carry a warning not to use on vegetable plants due to heavy metal content (nickel, I think) but no longer has that warning. Anything containing pendimethalin (crabgrass pre-emergent) should not go in your garden. I believe the label says nothing that is grown in soil treated with pendimethalin should be eaten for one year.

    I envy anyone who still has an active garden this time of year!

    As long as there are no pre or post herbicides no problem. I know many vegetables and herbs actually have a high demand for N.

    I would find this odd. When I worked in the agriculture, we used Prowl (pendimethalin) on sweet corn, field corn, and soybeans.

    It has been a few years since I recall reading this on the label, so I looked at a current label online. For LESCO's "Pre-M" product it says:
    "DO NOT treat plants grown for food or feed. DO NOT use treated plants for food or feed." However, it also lists acceptable uses on non-bearing fruit and nut crops, plus vineyards.

    In any event, the warning was not as strong as I recalled or stated above. Good catch, Grandview.

    I am not familiar with Prowl but looked it up online. According to - who I would not expect to exaggerate any pesticide as being at all safer than it really is - it says "Pendimethalin has many uses, on food crops, feed crops, non-food crops, and residential applications."

    In all likelihood just a CYA statement added onto the turf label designed to help prevent lawsuits.
