Even with temperatures bottoming out nightly in the thirties Central Texas lawns are becoming Weed infested and growth is evidently accelerated by daytime above average warmth.
I have an established Bermuda lawn about a year old. Located in the limestone rocky soil of Central Texas I decided to experiment control via the pre-emergent Weed & Feed.
Existing weeds were primarily Spurge family mixed with a variety of other broadleaf species beyond description intertwined with numerous grasses attempting footholds in the dormant Bermuda.
I physically removed, roots and all, all the visible examples, then applied the Fertilome according to bag instructions, actually weighing the amounts applied by the Scotts Turf Builder spreader for proper coverage. Application was during a month plus of drought. So After application in the first week of February I ran the sprinkler system long enough to get an inch and a half of rain equivalent.
After two weeks a healthy thick crop of broadleaf and scattered crabgrass resurfaced to my disappointment. No suppression was seen, at all. This explosion of growth appeared after a considerable rain shower had occurred.
Since this product is not really "cheap", I would not use it again. The " Dimension " is either ineffective or difficult to solubilize.
It is important to remember that the plants were already actively growing in your area. Even hand picking out the plants you can see will not stop seeds that have already germinated from sprouting. We believe that is what happened in your case. Once you see the undesirable weed species you will need to use a post emergent selective herbicide. Pre-emergent herbicides should only be used before the weeds species has been spotted that year. Please let us know if you need help selecting a product better suited to your needs. We are always happy to help! 866-581-7378
