can i seed grass after turf builder weed and feed

Answer: If you have more than 75% grass, you may be surprised how your good grass will fill in with four feedings a year at 6 to 8 week intervals. With this option you skip spring seeding (you can always seed in fall if your lawn still needs it). Here is a schedule for the year: Feed your lawn now with Scotts Turf Builder with Halts Crabgrass Preventer. In 6 to 8 weeks after your first feeding, feed again with Scotts Turf Builder Weed and Feed if you have lots of weeds or if you only have a few weeds, your second feeding can be Turf Builder Lawn Food and spot treat your weeds with Ortho Weed B Gon MAX plus Crabgrass Killer OR Roundup For Lawns. Put down Scotts GrubEx sometime in May or June. In 6 to 8 weeks after your second feeding, feed again with Scotts Turf Builder with SummerGuard to control insects. In 6 to 8 weeks after your third feeding, in late summer/early fall, feed with Turf Builder Lawn Food.

Here are your best two options:

Do you have less than 75% good grass with bare spots larger than a few inches in diameter?

Weed, Feed or Seed?

Do you have more than 75% good grass however your lawn is thin and weedy without widespread bare spots?

This is a big question in early spring: “My lawn needs everything what should I do first, put down seed or kill my weeds? The reason why this question is tricky is because many of the weed controls will harm new grass seedlings.

Answer: If lots of larger spots, then seed this spring. Be sure to use a special Starter Lawn Food plus Weed Preventer that is compatible with grass seed (the regular crabgrass preventers will keep grass seed from growing). If you do not prevent weeds when you seed, you are likely to be very disappointed as crabgrass and other weeds will germinate and choke out your good grass before it has a chance to take hold. A machine called a slit-seeder will help make sure the grass seed comes in contact with the soil. You just select the Turf Builder Grass Seed blend that is right for your conditions, such as sun, shade, heat-tolerant, etc. If you only have a few bare spots to take care of, consider Scotts EZ Seed. I think this is the best bare spot repair product we have ever sold! Spread the Starter Lawn Food plus Weed Preventer after you put down the seed. Feed your lawn again in one month after seeding with Turf Builder Lawn Food. Once your new grass has been mowed 4 times, you can kill weeds with Ortho Weed B Gon MAX plus Crabgrass Killer OR Roundup For Lawns.

1). If you only have a few small areas you want to seed, I have seen folks get around the fact that they have a crabgrass germination barrier in those spots by cultivating the soil to a 4 inch depth (to disrupt the crabgrass barrier), then mixing in an inch of compost like Scotts Turf Builder Lawn Soil, and then seeding with Scotts EZ Seed.

Scotts Turf Builder plus Halts Crabgrass Preventer and Scotts Lawn Pro Step 1 contain our best crabgrass preventer to provide prevention for around 4 months. The directions state that you should not plant grass seed for 4 months after application, which means you will need to wait until the end of August to seed. We have a different crabgrass preventer for folks who want to seed in spring and prevent crabgrass. Scotts Starter Lawn Food plus Weed Preventer and Scotts Lawn Pro Step 1 for New Seeding provide crabgrass prevention while allowing you to plant grass seed at the same time. (Note: the crabgrass prevention does not last as long as Turf Builder plus Halts and Step 1, however it is your best choice if you want to seed in spring.)

I hear that question quite a few times this time of year. I have two answers depending on the size of the lawn area that needs new grass seed. However, before I give those two answers here is a quick rundown of crabgrass prevention 101.

2). If you have a large area you want to seed, the first recommendation is not practical, so you really need to wait until early fall to seed.
