Jonathan Green‘s Green-Up Weed & Feed Lawn Food should not be applied immediately before or after seeding. Young seeds can be killed by the chemicals in the soil. The best time to apply fertilizer is during the growing season, when seedlings are still in the ground. Fertilizer is applied at the rate of 1 to 2 pounds per 1,000 square feet of soil, depending on the type of fertilizer being used.

For example, a 1-pound bag of nitrogen fertilizer can be used to fertilize a 10-foot-square plot of land. If the plot is 10 feet wide, the fertilizer will cover the entire plot, and if it is 1 foot wide it will only cover 1/4 of the area. Apply fertilizer in a well-ventilated area, away from wind and rain.

How long after overseeding can I apply weed and feed?

Pre-emergent herbicides kill grass seeds as they grow. Don’t feed or apply weed to a lawn that has been overseeded in the last 8 weeks. If you apply weed and feed before, don’t watch.

If your lawn has more than 1/2 inch of soil, it is likely that there is a large amount of grass seed on the surface of the lawn. If you are unsure, contact your local county Extension office for more information.

Can you fertilize after seeding?

After about 4 to 6 weeks after the seed starts to grow, you canfertilize the lawn with a high quality turf fertilization that is mostly nitrogen. The turf should be well on its way to forming a dense, healthy lawn about 8 weeks after seeding. Throughout the growing season, continue to mow, water and fertilize.

Can I apply weed killer after overseeding?

A general rule of thumb is to wait at least until you have mowed the new grass four times before using a standard broadleaf herbicide. At least three weeks after the last mowing of the old grass is when a standard pre-emergent should not be applied.

If you do not have access to a lawn mower, you can use a hand-held sprayer, such as a garden hose, to apply herbicides to your lawn. If you choose to use this method, be sure to follow the manufacturer’s instructions for proper application.

Can you spray weed killer after overseeding?

For a long time, professionals used to live by a simple rule when setting up a new lawn: never apply weed control as it will limit the ability to raise a healthy stand of turf. The weeds had free reign to grow and compete with other plants for food and water.

However, a recent study published in the Journal of Agricultural and Food Chemistry suggests that this rule may no longer be valid. In the study, researchers from the University of Illinois at Urbana-Champaign and the USDA’s Agricultural Research Service (ARS) found that applying herbicides to lawns can actually increase the number of weeds on the lawn, which in turn increases the amount of water needed to keep the turf healthy.

The study was conducted by researchers at the ARS, the U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) and Illinois State University’s College of Natural Resources and Environmental Sciences (CNRES). The research was funded by the National Science Foundation (NSF), the Natural Sciences and Engineering Research Council of Canada, and a grant from Illinois Natural Heritage Foundation.

Can you fertilize your lawn after overseeding?

You should wait until the grass is dry before you mow. The lawn needs to be fertilized six weeks after you sow it. For every 1,000 square feet of lawn, apply a pound of quick-release nitrogen fertilization. If you don’t have a lawn-mowing machine, you can use a garden hose to apply the fertilizer.

Mowing Before mowing, make sure your lawn is well-drained and that there are no weeds growing on it. Mowing is best done in the fall, when the soil is warm and moist, and when there is plenty of sunlight.

Should I put weed killer before grass seed?

You can spray it whenever you want, but you should not spray it again until your seeds are ready to be planted.

What is the next step after weed and feed?

You can leave the clipping on the grass for a few times after the weed and feed treatment is done. The clippings will help to mulch the turf.

Should you weed and feed before or after aeration?

Control of weeds. While research has shown that aerating your lawn after the application of a pre-emergent herbicide will not hamper herbicide effectiveness, aerate your lawn before applying these products so that you do not inadvertently apply too much of the product. Prevent weeds from growing in the first place. If you have weeds growing on your property, it is important to prevent them from spreading to other parts of your yard.

This is especially important if you live in an area where there is a lot of grass, such as in a city or suburban area. The best way to do this is to use a weed control product that is designed to kill the weeds before they can spread.

For example, you can purchase a product like Roundup Ready, which is formulated to be applied to lawns and other areas where weeds are likely to grow. You can also purchase products that are specifically designed for use on grass. These products can be purchased online or at your local garden center. Be sure to read the label to make sure you are using the right product for your situation.
