Dimension 2EW Herbicide should be used in early spring for maximum results with poa annua and crabgrass.
Please check out our lawn schedule for warm season grasses. This will give more insight on when fertilizers, pre-emergents, etc. should be applied.
Mulberry weed is an annual weed and can be prevented with the proper timing of pre-emergent chemical. The best pre-emergent for broadleaf weeds is dithiopyr such as Dimension 2EW. It should be applied in late March and again in mid-May. If you have a huge mulberry weed population, you can make a third application in early July.
Spot treating with something like Hi-Yield 2,4-D and/or a glyphosate based product will kill mulberry weed but care should be taken to avoid contact/drift with the gardenias as they could be injured as well.
Key is to kill or pull the weed before it drops the seeds, which the plant does a few weeks after germination. There is an article by UGA here that might help.
Dimension 2EW would be great as a pre emergent on fescue grass. Dimension 2EW herbicide provides preemergence and early postemergence control of crabgrass, and season-long control of crabgrass, goosegrass, foxtail, spurge and bluegrass annual. Please consult the product label for application.
The manufacturer recommends to water in Dimension 2EW inside 24 hours after application so it would be best if you apply it the day before rain is expected if you do not manually water the product in.

While Dimension 2EW Herbicide can prevent japanese stiltgrass when used according to label instructions, it would not control existing stiltgrass. Most applications for prevention will need to be made spring and fall for 2 years to prevent seeds that can lay dormant in the soil over time.
Dimension 2EW should not be applied within the drip line of any fruit trees. Also, the label does state that if your lawn is treated with Dimension 2EW, the grass clippings should not be left around the fruit trees.
Yes, buffalograss is listed on the Dimension 2EW Herbicide product label as tolerable with a note: Do not use this product on seedling buffalograss in the spring of the first year of establishment until the turfgrass is fully green and has established new roots
Yes, Dimension 2EW Herbicide can safely be applied to both cool season and warm season turf, including St. Augustine.
Typically you want to mix your Dimension 2EW or any chemical with room temp water or something close to that. Cold water can often cause products to have trouble emulsifying into solution.
To prevent sandburs you should apply Dimension 2EW Herbicide as a pre-emergent in the late fall. Be sure to read over the product label for complete instructions. Sandburs are easier to prevent than to try to get rid of once they have invaded your yard.
Dimension 2EW Herbicide should be applied when the soil temperature is at least 55 degrees Fahrenheit. This is generally done in early to mid March through the beginning of April depending on the temperature.
While creeping bentgrass is listed as a tolerable turf grass, the product label for Dimension 2EW actually states that not all varieties of creeping bentgrass have been tested. It also says do not apply to golf course putting greens, so we are unable to advise that it could safely be used on your home putting green. We would recommend confirming with the manufacturer directly to be sure. Dow AgroSciences can be reached at 800-992-5994.
Dimension 2EW is a pre-emergent herbicide, so it is best applied before soil temperatures reach those that are optimal for the weeds you are targeting. This is generally before soil temperatures reach 55 degrees in the Spring. You should not apply when there is snow on the ground or temperatures are below freezing. In the Fall, you would want to apply before soil temperatures cool to those favorable for these weeds, usually below 70 degrees. We recommend contacting your local Cooperative Extension for the best recommendation on timing in your area.
