ortho weed b gon and seeding

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.

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.

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.

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.

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’m not concerned about getting it perfect. If 10% of the seed I put down comes up and starts to spread over the years, I’d consider that a win. Every amount above that certainly welcome, but.

I just sprayed today, and it’s supposed to rain in 2 days (and a few days in a row). I was hoping I could toss down the grass seed tomorrow before rain, but I wasn’t sure if that’s too soon, or if it matters with this particular chemical.

Can I over-plant grass seed a day after spraying Ortho Weed B Gon? If not, how long do I need to wait (and why)?

I would remove the large wood chips with a rake, add a few bags of topsoil to level the ground if needed, and then throw some milorganite on the rest of the wood chips. It will speed the breakdown of the chips and improve the soil so it’s ready for seed.

I’m pretty sure that forsythia would be harmed if you get triclopyr (the active ingredient in Weed B Gon CCO) on the leaves of the forsythia plant. (The roundup would harm the forsythia, too.) Neither would hurt the forsythia after passing through the soil at normal application rates. If you spill the whole bottle at the base of the forsythia plant, that’s a different story.

Will this hurt forsythia if it gets on the branches or soaks into the surrounding soil?

Re: Weed B Gon CCO Questions

I’d like to apply weed b gon CCO but I have a few questions:

How long after application can I seed?

After a few rains the soil may settle, and you may need to add some more topsoil just before seeding. If necessary, Roundup can be used up until the same day you throw down seed.

Roundup or CCO are foliar applications, they only work when absorbed through the leaf. No concerns about spraying near the base of the forsythia. Be careful of drift though. if the spray drifts onto the leafs, you will have some burn. Not hardly enough to kill the plant, but the leaves that are sprayed will die.
