The lime you applied will yellow and may thin your centipedegrass lawn. Centipedegrass prefers acid soil with a pH of 5.5. Another option will be to use an irrigation system. Oak roots and grass compete for available soil water. In addition, be especially careful with ANY herbicide under the roots of a tree.
Many trees have a tendency to have root sprouts or shoots originating from injured roots.
When some herbicides are applied to that plant growth, the entire tree can be permanently harmed. So please, please read the label carefully before application of any herbicide. I am from Bladen County around the White Lake area. I am hoping you can help in telling me what type of azaleas will grow here in our sandy soil. Looking forward to hearing back from you.
