Should you Mow Your Lawn Before or After a Lawn Treatment?

A lush, green lawn is what you’re after in spring and summer. Who doesn’t want to sink their toes into velvety, thick, carpet-like grass? Can’t you feel your stress melt away just thinking about it?
Getting the healthy, thriving lawn that you want takes some work. To avoid unsightly brown spots and the effects of heavy foot and pet traffic, you need to care for your beloved grass. If you neglect it, there won’t be much to sink your toes into.

Regular, proper fertilization helps maintain the soil’s nutrients at a consistent level to keep your grass happy.

But you might be wondering whether you should mow before or after treating your lawn. After all, you don’t want to waste it.

Don’t worry. We’ve got your back. Here is everything you need to know about mowing timing around lawn treatments.

What You Should Know About Mowing Before or After Treating Your Lawn

During the growing season, you should be mowing your lawn about once each week.

As mowing frequency increases as the weather warms up, timing it around fertilization and weed control treatments can feel tricky.

These mowing tips and tricks should clear up any confusion.

Best Times to Mow Your Lawn

Fertilization, granular specifically, is rarely impacted by mowing. But weed control treatments can be impaired.

You usually don’t want to mow your lawn within 24 hours before any such treatment.

This is because if you mow right before an herbicide treatment, there isn’t much leaf area left to absorb the weed control. If a broadleaf weed control doesn’t come in contact with enough of the plant’s foliage, it won’t be effective.
How long do you wait to cut the grass after a lawn treatment? You should wait to mow for 24 to 48 hours post treatment . This is because it takes at least 24 hours for broadleaf weed control to translocate throughout the vascular system of the plant. If you cut the grass too soon, you’re not letting the herbicide get into the plant.

The Grass Clipping Benefit

When you mow after a lawn treatment, it’s always better to leave the clipped grass blades on the lawn.

These clippings act like barriers to help hold in the newly applied nutrients. Bonus: They also provide your lawn with organic nutrients to complement the fertilizer.

Remember the Mowing Basics

Whether you’re mowing your lawn before or after a lawn treatment, remembering the basics is essential to ensure your lawn thrives and you don’t waste your time.

First, make sure your mower is properly prepped. This means sharpening your mower blades, filling the tires with air, changing the oil, and ensuring it’s working correctly before the growing season is in full swing.

Then, when you mow, remember that your grass blades should be 3 to 4 inches tall after you mow. You never want to remove more than one-third of the lawn at any one time so as not to stress it out.

How to Mow After a Weed & Feed Application

Weed and feed products are often used by homeowners to kill weeds and green up the grass. Before applying these herbicide and fertilizer mixtures to the lawn, double check the label to ensure that you are using the correct product for your grass species. For best results, mow the lawn at the correct height and specified intervals before or after you apply weed and feed products.

Mowing Instructions

While each weed and feed product has specific instructions regarding mowing, generally you can mow the lawn one to two days before applying any weed and feed product or wait and mow at least one day afterward. Leave the grass clippings on the lawn for the next three mowings after application. Always mow the grass at the appropriate height for the species. Most warm-season grasses are maintained between 1 and 2 inches tall, while cool-season grasses are kept between 1 and 2 1/2 inches tall. Avoid removing more than 1/3 of the grass when mowing; if the grass has gotten too tall, mow on the highest setting, then wait a few days before mowing again to reduce the grass height to the correct height.

Weed and Feed Products

There are two basic forms of weed and feed products. One is intended for cool-season grasses and the other for warm-season grasses, often labeled as a “southern” weed and feed product. Check the label carefully for warnings regarding the use of the product on specific grass species.

Cool-Season Formulations

Weed and feed intended for bluegrasses (Poa spp.), fescues (Festuca spp.) and ryegrasses (Lolium spp.), all hardy in U.S. Department of Agriculture plant hardiness zones 2 through 7, should be applied in spring or fall when weeds are actively growing. The forecast should be clear of rain for at least 24 hours after the planned application and temperatures between 60 and 90 degrees Fahrenheit. Sprinkle the grass lightly to dampen it, then use a spreader to apply the weed and feed evenly over the lawn. Some products may also be used on warm-season grasses.

Southern Formulations

Southern weed and feed products are used on warm-season grasses, such as bermudagrass (Cynodon spp.), St. Augustinegrass (Stenotaphrum secundatum) and Zoysia (Zoysia spp.), which are hardy in USDA zones 7 through 10, 8 through 10 and 6 through 9, respectively. Apply the weed and feed with a spreader when no rain is in the forecast for at least 24 hours and temperatures are between 50 and 90 degrees Fahrenheit.

Warnings and Precautions

Do not use weed and feed products on dichondra (Dichondra micrantha, also known as Dichondra repens) and other broad-leaf lawn substitutes. Dichondra is a warm-season perennial groundcover, hardy in USDA zones 9 through 11. The broad-leaf herbicides used in weed and feed products will kill it.

In addition, do not use weed and feed products on new lawns. Wait 16 months after planting grass seed or plugs and three months after planting sod. Do not reseed bare spots for at least three to four weeks after applying weed and feed. Products that contain pre-emergent herbicides will prevent the grass from germinating.

Weed and feed products can affect other plants in the landscape, including shrubs and trees. Do not apply products that contain dicamba or triclopyr near or under the drip lines of trees. In addition, sweep any granules that land on sidewalks or other hardscape back onto the grass. When rinsing spreaders and other lawn equipment, pour the water on the grass, not down the storm drain to prevent herbicides and fertilizers from contaminating waterways.

Personal Safety Concerns

Wear a dust mask, safety goggles, gloves, shoes or boots, long pants and long sleeves when working with weed and feed products and mowing. Wash all exposed skin with soap and water and launder clothing after applying weed and feed. Keep pets and children off the lawn while applying the granules and until the dust has settled. Also, keep all bystanders and pets away from the lawn while mowing to prevent injuries from flying objects.

Do You Cut the Lawn and Weeds First Before Applying Weed & Feed?

Applying an herbicide and fertilizer combination — referred to as “weed and feed” by most retail outlets — can be an effective and simple way to build strong turf and a healthy-looking yard. Each weed and feed product can have different instructions, and it is always important to follow the directions on the label. Off-label uses, such as increasing the concentration or application rate from the instructions on the packaging, can not only harm your yard but may also be illegal.

Mowing

It is recommended that you mow a few days before applying weed and feed and that you wait a few days after applying to mow again. This ensures that the herbicide — the “weed” part of weed and feed — has time to be absorbed through the leaves of the weeds and can begin to work. Mowing height can help to battle weeds, but a careful balance must be maintained between keeping the weeds from going to seed and cutting the grass too short. When you use a mower deck height that is too high, you may allow weeds to mature and make seeds. Conversely, if you set the mowing height too low, you will damage the turf and weaken it, leaving vulnerable areas for more weeds to infiltrate the yard. Use a mowing height recommended by your local extension agent for the kind of turf you have.

Bagging

If you have a severe weed infestation and you are seeing seed heads popping up in your yard, consider bagging your clippings to reduce the spread of seeds around the yard before you treat with a weed and feed. After treatment, leave the clippings on the grass the next time you mow the lawn. They will help to mulch the turf, and the leftover weed and feed granules that have not been broken down and absorbed will be redistributed around the mowing area. The same applies to clippings treated with a liquid; the plant material that still has chemical left on or in it will break down and rerelease those chemicals back into the soil.

When to Weed and Feed

Weed and feed applications to an entire yard are only necessary if there are weeds in your entire yard. If the weeds are only present in specific areas, such as around gutters or under trees, use a fertilizer that does not have a herbicide and treat the problem weed areas separately with an herbicide for that specific weed. For help in identifying types of weeds, contact your county extension agent.

General Turf Help

Other lawn problems, such as insect damage, over- or underwatering, and animal damage can also contribute to weakening your lawn and opening it up to weed infestation. Look for large areas of discoloration, dead or dying grass, or areas that are thin. One of these could possibly be a fungus or insect signal. Use your local extension service website to help identify any lawn problems you have, and then treat those issues specifically. You may find that by simply watering less, you can slow a weed or fungus problem in your lawn.

A healthy lawn is a dense lawn, and it is difficult for weeds to grow in a dense lawn.
