new seed after scotts turf builder weed and feed

Scotts Super Turf Builder with Plus 2 Weed Control, now called simply Super Turf Builder with Weed and Feed, contains more nitrogen and phosphorus than plain Turf Builder Weed and Feed, to provide faster green-up. Super Turf Builder contains 29 percent nitrogen, 2 percent phosphorus and 3 percent potassium, while plain Turf Builder contains 28 percent nitrogen, no phosphorus and 3 percent potassium. The active weed-killing ingredients are 2,4-D and mecoprop. Environmental health agencies in some areas list 2,4-D as a chemical known to cause cancer or birth defects, so use with caution.

The Scotts website question-and-answer section states that grass seeds should be allowed to germinate and grow tall and strong enough to be mowed four times before you apply weed and feed. No entirely specific time period is provided, because different grass species grow at different rates, and growth is affected by many variables, including soil quality, temperature and rainfall or manual irrigation.

This turf builder weed and feed should be applied with a mechanical spreader for even distribution. When using a spreader, Scotts Turf Builder Plus 2 spreader settings vary depending on the device. Set broadcast and rotary spreaders at 3.5, hand-held spreaders on 3 and drop spreaders on 5. Even if you’ve used the turf builder products for years, always check the package directions to ensure that the instructions haven’t changed.

Wait for a calm day when temperatures are not expected to rise above 90 degrees Fahrenheit and no rainfall is expected for at least 24 hours. Water the lawn first to moisten the grass, or start the application when the grass is moist from dew. The product should be applied while weeds are actively growing in the lawn. A second application may be made, but wait at least 30 days — and do not use the product more than twice each year.

If you are unable to find Super Turf Builder Weed and Feed, Scotts Turf Builder Triple Action provides similar results. It kills weeds, prevents the new weeds from sprouting and feeds the grass.

Now here are my two answers:

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.

According to the Scotts Turf Builder Weed and Feed 3 product label you would want to delay application on newly seeded, sodded or sprigged areas until new grass has been mowed 4 times.

Scotts Turf Builder Weed and Feed 3 should be applied only to residential lawns, so we recommend avoiding applications to cacti/succulents.

You should wait until the new seed has grown enough to be mowed 4 times before applying Scotts Turf Builder Weed and Feed 3 per the product label.

Scotts Turf Builder Weed and Feed 3 is a post emergent with fertilizers. It could have impacted the grass seed growth as you sould wait at least 3 weeks after application of a post emergent to seed.

It is recommended not to mow within 2 days before or after application of Scotts Turf Builder Weed and Feed 3.
