Unfortunately Monterey Vegetable & Ornamental Weeder is not labeled to be used on or around onions. You will need to wait at least 4 months before planting onions after this product has been applied to a given area. If weeds are already an issue around edibles not listed on the label, we would recommend a glyphosate based product like RoundUp QuikPro to spot treat any weeds.
