P:
Once or twice a summer I treat my lawn with weed & feed and spray on weed killer for lawns. Is it safe to use compost made from the lawn clippings? How long should I reasonably wait to use clippings for compost, and is it safe to use the compost in my veggie garden the following summer?
R:
Mowing recommendations are to set the blade of the mower so that you remove one-third of the stand of grass with each mowing. If you follow that recommendation, you would dispose of the clippings resulting from the first three mowings following a weed-and-feed application. From the fourth mowing on, the clippings would be fine to include in your compost and to apply to a vegetable garden.
