St. Augustine and Centipede Problems
We moved into a home last year in East Texas that has about 1.25 acres of grass area. The perimeter of the property is heavily wooded with a stream on each side, and the center of the front of the lawn has a few trees as well.
Most of the lawn is St. Augustine, with some centipede mixed in.
This past winter, we had heavy rain, and as we sit on the low side of an area, so we get a lot of the run-off. Because of this, we have developed quite a bit of Dollar weed that I Can't seem to get rid of. Also, the grass just isn't coming in as well in areas as it was last year at this time.
I've put down some STa-Green combo fertilizer-weed killer specifically for this type of grass. It helped with some of the random type weeds ,but not most. I also tried using some Image weed killer with Atrizine in a small area as a test, and it did nothing at all for the Dollar Weeds.
I've done some soil samples in the yard (it's very sandy soil here), and the average looks as follows:
PH = 7.5
Nitrogen = Low
Phosphorus = Medium
Potassium = High
I'm at a loss as where to go from here as Bermuda is the only southern grass I"m familiar with.
Any help would be greatly appreciated.
