|How soon after applying Ortho max bug killer should I wait to put on weed and feed or 16-16-16 and what do I need to do about the bumps left over from those grubs?|
|According to the product label, you should wait 2 weeks after application to fertilize or apply weed killer to your lawn. As for the bumps, they will degrade on their own. Each time you water or it rains, the bumps will dissolve.
Best wishes with your lawn!
