Grasses and Weeding

Question

I have bermuda grass in my backyard, which is 5,000 sq.ft or bigger. There is a large maple tree in the middle. In some parts the bermuda grass is okay, but in other areas it is not flourishing because of weeds and tree. What product(s) do I need to get rid of the weeds and promote the grass? In the front I had St. Augustine – now only about 25% is that with the rest being weeds and winter grasses brought in by the wind. How do I save the St. Augustine?

Answer 1

If they are broad leaf weeds, you can use a broad leaf specific herbicide to help eliminate them. But if they are grass like weeds, you may not have any choice but to either hand weed or consider re-seeding the lawn. It sounds like you may have some underlying issues that are contributing to the loss of the desirable grass, though. Often when weeds set in like that, there is something about the soil keeping the desired grass from growing healthy and then giving the weeds an opportunity to get a foothold.
