| A weed is spreading in my lawn that is not being killed by the lawn friendly weed killer/herbicide I am applying (Ortho). A landscaper said this weed is very herbicide resistant because its roots are deep. He recommended that the using an herbicide that killed everything and then start the lawn from scratch. Any other ideas on ways to get rid of this weed without having to start the lawn over? |
| It would be helpful to know what the weed is before trying to offer control options. For instance, field bindweed (also called morningglory) is nearly impossible to eradicate without digging and using a vegetation killer (which can harm your other plants). Other weeds might respond with just hand digging. Try to have the weed identified - perhaps at your local garden center? Then if the staff there cannot suggest control remedies, submit a new question to this forum with the name of the weed and we'll make helpful suggestions. For instance, wild onions, wild violets and creeping charlie can all be controlled but it takes patience and persistence. A last ditch effort would be to use a vegetation killer and start all over with a lawn, but there's no guarantee the problem weed won't appear again because of seeds left in the ground. Sometimes you can dig out the existing weeds and use a pre emergent on the lawn in the late winter or early spring - the control methods depend upon the weed in question. So, have it identified and submit another question with the name of the weed. We'll do our best to suggest control strategies. Best wishes with your landscape! |
