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.
Yes you can mix Dimension 2EW Herbicide and 3 Way Max Turf and Ornamental Broadleaf Herbicide to give you both pre-emergent and post-emergent control.
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.
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.
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.
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.
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.
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.
Dimension 2EW Herbicide is going to be the best pre emergent product when controlling crabgrass. It is labeled to be used in Fescue lawns and can even be applied at a ratio to work as a post emergent.You will use .28-.73 fl oz. per 1000 sq. feet or .75-2 pints per acre. For your 2.5 acre property, 1.875-5 pints will be used to cover the entire area. Please read label for further instruction.
Dimension 2EW Herbicide is not labeled to be used in areas animals would graze so we cannot recommend it be used in the area. We actually do not have any pre-emergents for grassy weeds in pastures and would recommend contacting your local department of ag for assistance identifying the target weed and for a product recommendation. We can then see if we can get the product.
