When Can I Seed After Preventing Crabgrass?

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.

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.)

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.

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.

Can I Put Down Scotts Super Turf Builder Plus 2 If I Overseeded Four Weeks Ago?

A well-kept, healthy lawn should be plush, free of weeds and diseases, and as green as the neighbors’ envious hearts. Weed and feed products are designed to provide needed nutrients to the grass while poisoning weeds that want to steal the lawn’s food. Scotts Super Turf Builder with Plus 2 Weed Control works on several species of lawn grasses. While the company’s website recommends waiting four weeks to put down grass seed after applying the weed and feed, seeding first means waiting a different length of time before you use the product.

Healthy Lawn Chemistry

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.

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.

Timing Is Everything

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.

The Nitty Gritty

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.

Before applying any fertilizer or herbicide product, put on a mask, safety goggles, gloves, long sleeves, long pants and closed toe shoes. After applying the weed and feed and cleaning the spreader, wash your clothing in hot water and detergent to remove any dust or residue.

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.

Scotts Turf Builder Plus 2 Liquid

If you have a very small lawn, an alternative to the granular Scotts weed and feed products is the Scotts Liquid Turf Builder with Plus 2 Weed Control. This liquid fertilizer provides a quick boost of nitrogen as well as killing clover, dandelions and other weeds. Simply attach the garden hose and spray the lawn when the weeds are actively growing.

Use It Carefully

Make sure the product does not spill or drift on the wind to desirable plants, and don’t use it within several feet of fruit or vegetable plants. Sweep up any fertilizer that drifts onto sidewalks or driveways and toss it back onto the lawn.

Do not apply on St. Augustine grass, including the Floratam variety. St. Augustine grasses (Stenotaphrum secundatum) grow best in U.S. Department of Agriculture plant hardiness zones 8 through 10. The product is not appropriate for carpet grass (Axonopus affinis), which thrives in USDA zones 9 through 10, or dichondra (Dichondra spp.), a creeping ground cover often used in place of standard lawn grass in USDA zones 7 through 11.

How Many Days Do You Have to Wait Before Seeding After Weed & Feed?

You want a beautiful lawn for your family to enjoy, but it’s no longer enough to just mow it. You have to fertilize, water, kill weeds and then reseed any bare spots. Using a weed and feed product saved you some time, so now you’re ready to plant some grass seed. You may have to wait a bit longer, though, depending on the type of weed and feed product you used.

Weed and Feed

Weed and feed products consist of fertilizers such as nitrogen or potassium, and a pre-emergent or post-emergent herbicide. If the weed and feed is designed for spring application, it contains a pre-emergent. If it is designed for later in the growing season, it incorporates a post-emergent herbicide. Knowing which one you are using is important because the herbicides affect plants in significantly different ways.

  • You want a beautiful lawn for your family to enjoy, but it’s no longer enough to just mow it.
  • Using a weed and feed product saved you some time, so now you’re ready to plant some grass seed.

How They Work

Pre-emergent weed and feed is applied in early spring so the herbicide is in place before the undesirable weeds germinate. Pre-emergent herbicide works by inhibiting germination. It must be watered with at least one-half inch of water to move the chemical from the surface into the soil. Post-emergent herbicides, however, must be applied while the weeds are actively growing because for the chemical to work, the herbicide must be absorbed into the plant.

Why You Wait

Since weed and feed products are designed to prevent germination — or to eradicate a living plant — they can, for the most part, have a similar effect on young turf grass. The only exception is the pre-emergent herbicide siduron, which is actually used to assist in seed germination. When using a pre-emergent that does not contain siduron, wait a minimum of two months before seeding. If using a product designed for broadleaf weeds, read the label carefully, because the active ingredient in these post-emergent herbicides have a wider range for the waiting period. Grass can be planted in as little as one month after application for products using 2,4-D to as much as six months for atrazine-based products.

  • Pre-emergent weed and feed is applied in early spring so the herbicide is in place before the undesirable weeds germinate.
  • Post-emergent herbicides, however, must be applied while the weeds are actively growing because for the chemical to work, the herbicide must be absorbed into the plant.

Proper Seeding Methods

When you are ready to seed your lawn, use a garden rake to remove debris and to break up the surface to ensure the seed comes into contact with the soil. Broadcast the seeds in two directions to ensure complete coverage, and water the ground lightly and often for up to two weeks — keeping the soil moist. Once seedlings have established, gradually reduce the frequency of the watering, but lengthen the amount of time per watering. This will encourage a deep root system for your grass.
