How long you must wait to plant grass seed after treating your lawn with a Scotts Weed B Gon product depends on which product you use. When fighting broadleaf weeds such as dandelions with the basic Weed B Gon weed killer, wait at least three weeks to sow your grass seed. This product specifically targets the seeds of broadleaf weeds, but it can stop or slow down your grass seed’s germination as well.
When fighting grassy weeds, you must wait a little longer to plant your grass seed, whether you’re seeding your entire lawn, overseeding or treating bare patches. With the Weed B Gone Plus Crabgrass Control, wait at least four weeks to plant seed. Because this is specially formulated to stop grassy weed seeds from germinating, it also can stop your regular grass seed from growing.
With Crabgrass Preventer
Although you can’t spread grass seed at the same time you spray your lawn with Weed B Gon, other options exist to treat your lawn for weeds at the same time you plant seed. These typically come in the form of weed and feed products that offer fertilizer along with the herbicide. Look for products specifically designed to be spread with grass seed, often noted on the label as a starter fertilizer plus weed control.
Keeping your lawn weed-free is a constant battle that uses cultural practices, such as deep waterings, to encourage grass to choke out weeds, as well as chemical products, such as using Weed B Gon, to kill weeds before they start. These chemicals often kill grass seed as well, keeping it from germinating along with the weed seeds, so wait before you sow your seed.
When you’ve already planted your grass seed and want to apply a pre-emergent herbicide to keep weeds from competing with your new grass for water and nutrients, have a little patience. Applying a weed-control product such as Weed B Gon too soon can kill young grass. Instead, wait until you’ve mowed the new grass at least three times before using herbicides on your lawn.
I live in 05452. We have very sandy soil which was taken over by crabgrass last summer. Not even sure where to start? What are your thoughts, when do I do what? Also what are your thoughts on aerating? Thanks. Laura
Hi Ashton, I live in area code 14047. My lawn a former field and or pasture has many weeds and bare spots. I have no idea what type of grass it is and don’t know where to start. Please HELP! Paul
I live in area code 45044. I just applied Turf Builder with Halts Crabgrass Preventer. I already have a lot of crabgrass in my front yard. I was wondering if I applied this too late to see results with the crabgrass? Should I try Ortho Weed-B-Gon, and if so when should I apply this after I’ve applied the Turf Builder?
Time for me to cure my lawn. I have about an acre and a half, my back yard is a sandy soil some shade, in the shaded area grass does not grow lots of weeds. As we come forward soil get darker grass grows better, but still have dandelions, crab grass and this continues out to the front yard.
I do seem to have a lot of bugs too. Where do I start ?
I live in 20601. On 4-8-13 I applied Step 2 Weed N Feed to the backyard. 4-15-13 to the side and partial front yard (it rained later – not poured). I have moss on some of the front also. I need to apply the moss plus the crabgrass preventer plus some seed for some areas. What do you suggest? How to tackle moss, put seed down in various areas and then tackle crabgrass?
Bermuda likes sunny areas, so if you have shade the grass will be thinner. St. Augustinegrass can tolerate more shade. This is a good time to seed Bermuda. Put down some Bermuda seed and some Starter Lawn Food and don’t let the area dry out for long periods of time. If you have only a few bare spots to take care of, the Scotts EZ Seed with Bermudagrass is a good way to go, as the mulch helps to keep the seed moist. Stay away from the weed controls in the areas you are seeding. Feed again with Turf Builder for Southern Lawns a couple of times this summer. Once your new grass has been mowed 4 times, you can spray your weeds with Ortho Weed B Gon MAX plus Crabgrass Killer, however pick a day when the mid day temps are not in the 90’s or above.
Good grasses in your area are: Ky. Bluegrass, Perennial Ryegrass, Fescues. Put your Snap Fertilizer with Crabgrass Preventer as soon as you can as you are in prime crabgrass germinating time in your area right now. Water after putting down for at least 30 min. Your grass will do great with about an inch of water a week from rainfall or irrigation. Get a rain gauge to monitor your rainfall and you can place it in your lawn when you turn on your sprinklers to measure how much you have watered to get an inch a week. If you are not getting rainfall, irrigating a half inch twice a week is better than watering every day.
