Green Onions / Leeks are NOT listed on the Ready to Use booklet.
Unfortunately, according to the manufacturer the Captain Jack's Deadbug Brew Ready-To-Use cannot be used on leeks (green onions). We recommend that you contact your local cooperative extension office and speak to the master gardener on staff for more advice on what you can use on these edible plants.
