weed b gon and seeding

Thanks for the info. So if I do the crabgrass preventer this week when should I try to grow grass in the bare spots and what products should I use? Also any recommendation on products and timing of grub control?Thanks.

Hi Amy
I do not think you applied too late, because I would be surprised if crabgrass has germinated yet in your part of Ohio. For example, in Marysville we usually see crabgrass germinate around May 1. The first to sprout would be near a sidewalk where the soil warms first and the seedlingss would be very small. Ortho Weed B Gon MAX plus Crabgrass Killer would kill these. If you are looking at mature grassy weeds, these are likely perennial grasses with no product recommended that would not kill your good grass.

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

Hi Paul
You need to decide whether you should kill off everything and start over or to improve what you have. Since the kill off everything and start over option is best done in Late Aug/Early Sept, you have two options. The first option is to nothing till late summer when you start the process by killing your lawn with Roundup. The second option, and the approach I have seen others take in your situation is to feed your lawn a few times to see how much good grass you have (you may be surprised). Then make a decision on what to do next in late Summer. If you decide to do this, feed now with Turf Builder with Halts Crabgrass Preventer and then again in about 6 weeks with Turf Builder Weed & Feed. You can then decide if you want to keep improving your existing lawn by feeding two more times in fall or to kill it off and start over with new grass. I will be happy to guide you with the proper steps… check back with me around mid August.

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 Pablo
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.

Ashton, thanks for the link. How would you define good grass? I don’t have many bare spots at all, just some yellowing spots and thin spots. Since I only have the Snap system I am thinking of using Scotts® Snap™ Fertilizer with Crabgrass Preventer this weekend in ZIP 10710. Also how often do you water once you drop the food?

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.

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.

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.

With Crabgrass Preventer

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 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.
