Want to Seed and Prevent Weeds?

March 18, 2013

I am really excited about a new product that will prevent lots of different weeds from germinating, yet allow your grass seed to grow and thrive.  This product is a big improvement over one we have sold for years.

Click here to read the details about Scotts Starter Food for New Grass Plus Weed Preventer.  You will find that you can use this special product when seeding Kentucky Bluegrass, Tall Fescue, Fine Fescue, Creeping Red Fescue, Perennial Ryegrass, and Centipedegrass.  It contains a special food for new grass plants.  And the big news is it prevents these weed seeds from germinating for up to six weeks:   Large crabgrass, smooth crabgrass, dandelion, broadleaf plantain, buckhorn plantain, carpetweed, common chickweed, common lambsquarters, common purslane, corn speedwell, ground ivy, hairy bittercress, henbit, parsley piert, Pennsylvania smartweed, persian speedwell, pokeweed, purslane speedwell, redroot pigweed, shepherd’s-purse, velvetleaf, white clover, yellow woodsorrel, flatsedge, and, yellow nutsedge. 

This six week “weed non-compete timeframe” helps allow your new grass seed to grow stronger without being crowded out by germinating weeds.  This product is especially important if you get a dump truck load of topsoil that was scraped off of a field that was loaded with weeds.

A big thanks to Scotts R&D Team!

    Why is there no label available for this product on Scotts website or anywhere? Why is there no option to read the label on the bag on any store website (Blurred out)? What is the active ingredient? Is the active ingredient a registered herbicide for the state of RI?

    i have your quick fix mix grass seed in florida put it down a week ago and nothing ,also raked and spread top soil what is wrong ,kurtis..

    • Hi Kurt
      Quick Fix should germinate in 7 to 14 days. When I have had germination problems it is usually because:
      – I covered the seed too deep (I give one pass with an upside down leaf rake to mix the seed very lightly in the top 1/8 inch of soil. Most of the seed is still on the surface after this pass with the leaf rake, which is ok. If the seed has too much soil over top it will likely not germinate.)
      – I let the seed dry out. This is more of a problem on sandy soils.
      – A weed killer or preventer was used in the area that keeps grass seed from germinating. My neighbor down the street had this problem because his lawn service had put a weed treatment down and he seeded with no result.
      – The soil was too cold. I do not think this is your problem.
      Hope this helps.

    I have been using Scotts turfbuilder + 2 for about 3 years and each year
    the weds stay healthy and I can see no positive results.5 or 6 years
    ago I use Scotts and always saw results I was wondering if due to
    epa regulations you had to weaken the product.

    • Hi Howard
      The Turf Builder plus 2 weed & feed has the same active ingredients and amounts now as in the past. There have been some changes to the feeding but not the weed controls used. Not sure why you have seen a change in the results. I know for myself I have found that putting the product down first thing in the morning when there is lots of dew on the grass and no rain is expected for 24 hours is when I get the best control. If the weather has been dry for several weeks I find the weeds do not take up the killer as well as they are not actively growing. Some kinds of weeds are harder to control than others and coming back with a spot spray of Ortho Weed B Gon MAX plus Crabgrass Killer will usually do the trick. Good Luck with your lawn.

  4. WHAT is the product name ?

    Good morning,

    I have a question regarding weeds. 2 years ago my grass was greener than green, plush, and just a beauty. Next door neighbor’s yard soon became overloaded with weeds. Sad to say is that seeds made it to my beautiful St. Augustine. I am in rebuilding mode now because last year my yard was a mess.
    Will regular feedings eventually push those weeds out and my St.Augustine flourish again. Or do I have to start all over again? (I killed whatever was previously there, layed new dirt and sodded entire yard myself)

    I already fertilized with Scotts (Bonus Maxx i believe)

    • Hi Adrian Bonus S MAX was a good first feeding because it will help with the weeds and help with the insects. I would guess that the weed problem took off when your grass was weakened by insects like Chinch Bugs and Sod Webworms. The good thing about St. Augustine is that it will spread to fill in thin areas when you feed it regularly. Four or five feedings this year will make a big difference in how thick it gets crowding out weeds. The Ortho Nutsedge Killer also can be used to control many weeds in your grass.

  6. Adrian permalink

    That is correct on the bugs.
    Do you only recommend Bonus S MAX for feedings? On the Ortho Nutsedge Killer, when do you recommend applying that? (I fertilized 3/16/2013)

    Thank you

    • Hi Adrian Yes, Bonus S MAX gives a good feeding. As long as you have weeds, you could do another application of Bonus S MAX 6 weeks after your first application. The OrthoNutsedge Killer can be used anytime the weeds are actively growing. This would be a spot spray. Check the weed list on the package to see what it controls. Once your weeds are under control, your best choices for feeding and thickening up your grass are Scotts Southern Turf Builder or Scotts GreenMax. In summer you would want to consider an application of Ortho Bug B Gon MAX or Ortho Fire Ant Killer for the insects. (Your next application of Bonus S MAX will carry you until summer for insects.)

      • adrian permalink

        Ashton, I’m sorry I used Green Max on 3/16 not Bonus S. Do you suggest Bonus S or Green Max when I feed again late April?

        Sorry about the confusion.

      • Hi Adrian In addition to your next feeding, you would get some weed control and insect control with Bonus S MAX or weed control with Bonus S. You could put either of these down as early as mid-April.

      • adrian permalink

        I also just layer 32 squares of sod alongside sidewalk where it had just died.

      • Hi again Adrian Keep it watered. If you can you can speed up new root growth by feeding this new area with Starter Lawn Food.

    We just seeded/established a new lawn last fall and after reseeding some thin areas applied Scotts Starter Food for New Grass Plus Weed Preventer March 30. I am desperate to keep my neighbor’s crabgrass from creeping into our new lawn – every year they have tons of crabgrass. I understand Scotts Starter Food for New Grass Plus Weed Preventer affords 6 weeks of prevention from crabgrass and some other weeds. What do you recommend to apply after that 6 weeks in order to keep control of crabgrass through the fall? I am in the midwest, Chicago area.

    • Hi Stephen
      You have two options: If you are suspecting big crabgrass pressure, you can put down Scotts Turf Builder with Halts about 6 weeks after your Starter Food for New Grass plus Weed Preventer application. The other option is to feed your lawn with Turf Builder and then spot spray any young crabgrass (as well as other weeds) with Ortho Weed B Gon MAX plus Crabgrass Killer if the problem arises. If your lawn if relatively thick and you are mowing at a taller mowing height (2-1/2 to 3 inches after the cut), the second option may be just fine because your thicker, stronger grass will shade out most crabgrass seeds that try to grow.

    I just overseeded my lawn and used Scott starter fertilizer. How soon can I use the scotts turf builder?

    The active ingredient in this product is mesotrione which suppresses annual bluegrass. It seems like there is enough active ingredient for Poa Annua suppression. Any way to check on this? It would be a real plus even if this product suppresses a portion of Poa Annua seed. Thanks!

    • Hi Greg
      I think the best option for Poa Annua prevention is to put down Halts or Turf Builder with Halts around sept 1.

      • Greg permalink

        Thanks but I am seeding my lawn this year and planned to give this product a try. Can I apply it again in 4 weeks after my initial application?

  10. Hi Greg
    6 weeks is the suggested interval between applications. Poa Annua is not listed on the weed list. Halts does prevent Poa however you can not apply until your new grass has been mowed 4 times.

    • Greg permalink

      Hi Ashton,
      Just wanted to let you know that I used this product for my Kentucky Bluegrass renovation this past August. I put it down at seeding and again 6 weeks later. It is by far my favorite Scott’s product. Not only did it keep the weeds out but suppressed the Poa Annua as well. Mesotrione, the active ingredient, has been known to suppress Poa Annua when seeding new grass. Many people have used the liquid form of Mesotrione to suppress Poa with success. Compared to my lawn care friends who used the liquid, the Scotts granular product did as good of, if not better job at preventing both weeds and Poa. I’m guessing because the granular is so easy to use and get the dosage correct while the liquid product is very difficult to apply. Anyway, I think Scott’s should test this product for Poa Annua suppression so they can add it to their label. Regardless, I’m thoroughly convinced it works for Poa suppression as I had a total of 3 Poa plants in my 12,000 square foot renovation. Having so few Poa plants germinate in a renovation this size is simply amazing, as those who have battled Poa Annua while seeding can attest to. Thanks again for recommending this great product!

  11. Since our last conversation, areas 2×2 to 3×6 feet brown/reddish spots have appear on my lawn. What is going on? I last used the bonus s with bugs b gone last week.

  12. Hi AJ
    Not sure what you are dealing with. The feeding/weed control/insect control you just did should set your lawn up for improvement. There is a lawn fungus problem on St Augustine called Brown Patch this time of year. The patches are circular brown with a darker area around the edges. You might wait a week or so to see how your lawn is doing before treating with Scotts Lawn Fungus Control.
