    Applied product and watered/rained moderately for several days on a daily basis. After the 4th day, splotches of yellowing appeared. I thought it was just an isolated spot but it progressed to several areas across the lawn where the product was applied. The areas where product wasn’t applied were unaffected and still thriving (green). Complete waste of time and money, causing damage that can’t be repaired until all the chemical works its way out because it can kill new grass germination. I fully expect the problem to worsen as more of the product is absorbed. I would have rather used an ineffective product than this one which is harmful.

    If you have a nice lawn and like to keep it nice and green don’t use this product. It doesn’t kill the crabgrass but it kills your good lawn. Thanks for ruining my nice lawm. Will never purchase your product again.

    This is a pre-emergent crabgrass control.That means it needs to be applied before you see crabgrass in your yard. For most parts of the country, that means March and April. If you apply it in May, June July,etc… it won’t work. Thats when you need to use a product like Ortho Weed B Gon.

    Apply this early in the season. Just before the forsythia shrub blooms is a good indicator. Thats the earliest plant that usually blooms in the spring-bright yellow flowers-if you apply after that, it wont be very effective.

    Im in Michigan and as soon as the temp hits 50-55 degrees for 3 days in a row, its time to apply. I’ve used this for years and it works.

    Product spread well through my spinner push spreader with no clumping or clogging. The grass is greening up well with the shot of nitrogen inspire of the intemperate local weather. So far, no signs of the crabgrass in the newly planted borders of a public park walkway that abuts my property. Last season it was over-run with crabgrass as the township did not get the strips along their new concrete walk/bike way planted with sufficient density or early enough. I planted last fall and have a stand. If the Sta-Green does its’ thing, the township will have a “lawn” and I won’t have a mess next to my property.

    I applied this to my yard 3 weeks ago and now everyplace I applied it the grass turned yellow and died. I have made no other changes and grass remains cut at 3″ so I am assuming it was the product.

  6. Spinrbait

    Ive tried every kind of weed and feed out there. Sta green is as good as any and better than most. I use crab ex plus twice a year, and crab ex twice a year. (Every 3 months). I use a post emergent 24d in late feb, or early march to kill spurweed. No preventative works very well on that. But crab ex does the best on it. I have a Bermuda lawn fwiw.

  7. Carl

    This product works as intended. If you try to use it to kill existing crabgrass as one reviewer did, it won’t work (so you can ignore his 1 star review). Apply in early Spring per instructions before the crabgrass germinates.

  8. Nconfer

    I use based upon 1 lb of nitrogen per 1000 sgft (30% nitrogen @ 45 lbs = 13.5 X 1000 = 13,500 sqft per bag) where the bag says it covers 15,000 sqft. It works very well when I use it at least 3 times per year. Application times are early spring, early summer and late fall or even early winter. Application is best when done just prior to a good rainfall as long as heavy rain does not carry off the product. A week after application I spray with Spectracide weedstop plus crabgrass and yellow nutsedge killer. All broadleaf weeds and most young grassy weeds will be dead a few weeks later. If you cut the grass regularly and pull any remaining established grassy weeds by hand to prevent their seed from getting into the yard you will have in a short period of time a nearly weed free yard, and in 3-5 years most seeds already in the yard will be dead and unable to germinate. Hope this helps.

    My crabgrass decreased by about 90% from previous year. Just make sure you put it down before the crabgrass germinates. In our locale, crabgrass comes up in May so I applied it in April. This product also provides a lot of nitrogen for the price.

  10. Bill

    20% less expensive and just as effective as the more expensive brand

    grab-grass was taking over my lawn. a friend told me to use Sta-Green. It has worked great. Grab-grass is gone the lawn is green and nice. LOVE IT.

  12. HVCCCaddie

    I buy the cheapest brand of “crabgrass preventer” every year, and they all work. This one works also. People are reviewing this as if it’s a “weed killer”. It is not! Crabgrass preventer goes down early in the season, before crabgrass germinates. If you apply too late, crabgrass that is already germinated will not die. Weed killer kills actively growing weeds (not including crabgrass), so you apply later in the season.

  13. RG

    This is a great product when used properly and if the user understands what it has be formulated to do. This is a Pre-Emergent, it will not kill existing broad leaf weeds such as crab grass. However, if you read the instructions and put this product on your yard around the 2 week in Feb. (Depending on your location) it will prevent the weeds from germinating. You will also want to put it down again in late Aug. I have zero weeds in my yard!!!!!!

    Applied Three weeks ago and my grass has never been greener. I’ve been using it for the last two years and I have noticed a significant reduction in weeds that come up in the Spring also. I feel that it works as good as or better than Scott’s Brand.
    A friend recommended it to me and I am glad he did. I highly recommend it. It does a great job and will save you money.

    I wet the yard, and applied the product at the specified rate using a broadcast spreader. I even applied a little extra directly to the crabgrass, just to make sure. I gave that a day as is, and then watered the lawn well the following day. I had a good rain about 12-16 hours after i watered. Per the directions, the product should activate properly with a 1/2″ of watering. It got it.

    Some of the crabgrass has some light brown spots on it. The rest of the crabgrass is growing just as strong as ever. At this rate, I would be better off with some roundup and a 1/4″ paint brush to treat each of the weeds individually. I know it works.

  16. Mike

    The bad reviews are written by people that don’t understand how to use Prodiamine, the active ingredient in this product. This needs to be applied in early spring to prevent weeds from growing. Do not buy this if you are trying to kill crabgrass that has already grown because it won’t do anything!.

    Here in New Hampshire, that means you apply it around the first 2 weeks in April and it prevents most weeds from growing. Anytime after that it’s not going to do much of anything.
