Rated 4.0 out of 5.0 by DearDeb First time using.
Have been overrun by weeds and wanted to put a premergent down and I think I timed it just right this year. I put it down around March 15 but we were supposed to get rain and didn't so I hand watered the grass. It don't seem to help the broad leaf weeds as much as others. I will follow up after it rains and not expecting anymore rain within a couple of days with the weed and feed to try and kill the ones that have already came up. But I'm impressed so far.

Rated 5.0 out of 5.0 by Verified Reviewer Good product, inexpensive weed control
Product works as described, name brand product that lasts for roughly 2.5 months in the hot southern temps. Must be applied PRIOR to weed germination normally first week of March for folks in the south. Must be watered in (ie with rain) and then reapplied after a couple months. This is an effective and inexpensive way to prevent weeds. You won't get them all and as such you'll have to hit them with a spot treatment but for big areas this product does work if used and applied as required. IIRC I apply using the 4# rating, for me it's a 5.5 setting on my el cheap Scotts rotary spreader.

Rated 5.0 out of 5.0 by BarBQLuvR Works well; good value
I have been using this product now for several years now and have not had a blade of crabgrass since. It is a good value when compared to the highly advertised alternatives. The product has never harmed my lawn, no yellow patches, no blotches. You would never know that any product had been applied to the lawn except for the lack of crabgrass and other weeds. I use it in the fall to prevent chickweed.

Rated 4.0 out of 5.0 by WoodinVirginia If you red the DIRECTIONS the product works
Better then Any Scott's product I use this in mid Nov And again in March with the 19-0-7 formulae in March to keep my yard's fescues grass happy and weed free. I use in conjunction with Milorganite because my lawn does not need excessive Nitrogen to look good and grow lush, have been convinced now that the way to keep my lawn and my pocketbook happy is to back away from those products that continue to increase in cost $$$ but don't add any real value . As for it turning your yaard yellow the directions warn you to keep yo and the kis and the pets off of it until it has been watered in. All chemicals should be applied with long sleeves and long pants ,eye protection,a face mask and gloves. This is a professional Prut,if you can't follow the directions,perhaps you shouldn't be using it !!

Works as well as anything I've tried at half the price of the leading brand; Needs to be applied twice per year within narrow 10-14 day window (when depends on area), or don't bother.

Rated 1.0 out of 5.0 by IHateWeeds Weeds as Prevalent as Ever
This product simply did not work for my lawn even after making sure that the product was applied according to manufacturers recommendations. I have as many weedy grasses now as I have ever had. I am just $20+ poorer for the experience not to mention the time wasted applying the product.

Rated 1.0 out of 5.0 by LordBobo I hope you really really like YELLOW
I had read on other lawn site forums that people hated PRE-M and that they were all so happy to move on to any other product at all due to the (from a lawn business standpoint) liability of staining clients property yellow. I guess it's agreed that it's less of a problem with the granulated variety vs the spray type, so I assumed this granule variety was fine. IT'S NOT.
The dust this stuff generates when it's being run through a spreader sticks to EVERYTHING. It wasn't even a windy day or something. It just generates a lot of dust, and it sticks to everything. My hands were yellow, my clothing still is yellow. I had to wash my hands twice to get it off, and then when I used a kitchen towel to dry my hands off, I had apparently missed some trace amounts, so now that towel has yellow stains.
If you leave it on concrete, and that gets wet, then your concrete is stained. EVERYTHING this touches turns yellow. It wouldn't be so bad if the dust wasn't so sticky, and it's not like you can brush or even blow it off. Once the dust comes in contact with something, then that's it, it's gonna be Yellow.
Keep your dogs and kids off the yard, especially your dog. You'll have to get him washed immediately, or he'll just become an outside dog until that stuff goes away (months probably). If the dog gets yellow on him/her, and then it comes into your house.. YELLOW.
I really can't believe there's not a warning label on the bag regarding it.
No clue how this works on weeds yet. Other forums says it can sometimes deform grass root growth, but it was used for years before Dimension came along, so it's probably fine as a preemergent. If you don't believe me, just Google it. Forum after forum of professional lawn people hate using PRE-M (this product) because it stains EVERYTHING YELLOW (even the granules).
