No, a vegetable garden that has been sprayed with Weed & Feed cannot be repaired if the crops are annuals even though yes, it can be repaired if the crops are perennials. An 18 to 24-inch (45.72 to 60.96-centimeter) barrier must be respected between areas that are sprayed with the herbicide in question and the root zone of annual and perennial edibles and ornamentals. Annuals must be dug up and destroyed while perennials will require a year wait before harvest.
