Define the Status of Your Lawn at the Moment
From the very beginning, you need to identify the current situation with your grass and the condition of your lawn.
Grass density – The problem in your yard will begin from the moment when you spot first patches of dirt located between the grasses. We can talk about insufficiently watered parts without enough nutrients which will be real weed-magnets in your yard. If you miss solving the problem on time, you can expect this place fills with unwanted weeds.
Thatch – A matted layer of grassroots and various dead stuff means that you have some thatch on the surface of the soil. As long as this layer is about a 0.25 to 0.5 inches (0.6 – 1.3 cm) thick, you don’t have any reason to worry about.
The layer of thatch will help with providing organic matter for grass, slowing the evaporation from the soil, protecting grassroots from high heat during summer, and even slowing germination of weeds seed.
However, if this layer is more than 0.5 inches (1.3 cm) thick, it will probably cause problems including choking out your grass. Also, your lawn won’t get enough water during light rain since thatch will absorb all moisture.
Grassroots depth – When your grass is weak with shallow roots, it can’t reach the necessary nutrients from the soil. Keep in mind that health grass needs at least 6 inches (15 cm) long roots. Otherwise, you can expect weeds spread around.
Weed spread – You can be sure that you will lose a fight against weeds if it has spread to over 50% of your lawn. Determine the type of weeds and the surface of the affected yard and decide if you need to kill all of them immediately or to deal with a piece by piece of it over time.
The Types of Weeds
The most common weeds you can find on your lawn are divided into three basic categories:
- Annual weeds – This type produces its seeds during only one season.
- Biennial weeds – This type produces its seeds during two consecutive seasons.
- Perennial weeds – This type produces its seeds during a long time. Its well-established roots allow this grass to overwinter and start growing again in spring without any damage.
The Way to Restore a Lawn Full of Weeds
Once your yard is full of weeds, your grass can’t grow healthy and green. Be prepared that you can’t solve the problem quickly, but it is not impossible if you are persistent and have a strong will to restore your lawn.
Step 1. Cleaning and mowing
Start with cleaning your yard. Get rid of as many unsightly clusters of weeds as possible by using a small hand-shovel. Tearing the weeds off at the surface of the ground is not enough. You need to move the entire plant including roots.
Also, don’t leave pulled weeds to lie on the ground. When you mow your lawn the next time, you will chop weeds up and inadvertently replant them.
While mowing your yard, no matter if you use a reel mower, self-propelled lawn mower, or electric cordless lawn mower, pay attention to blades and set them at a high setting. While your grass is vigorous, tall, and thick, you won’t have any problems with weeds.
Step 2. Weed killer
Use a sprayer and apply the weed killer directly to the weeds. Try to avoid healthy grass since even best herbicides can damage it. Do it at least three weeks before the term for setting up a new lawn.
Step 3. Aeration
To aerate your land correctly, you can use both hand or power tools. Just push a tube into the ground and leave an open hole while moving out the tiny plug of the soil. After forming the loose soil, roots of your grass can grow deeper into the ground, and both fertilizer and water will penetrate quickly and reach deeper layers.
Use the turf aerator and aerate your yard from one end to the other. Start in a horizontal direction and keep going diagonally from one corner to the opposite one.
That is the best way to help air reach even the deepest grassroots. This process is the only solution for a high-traffic lawn, especially if it contains mostly clay.
Step 4. Plant new grass seed
The essential part is planting new, weed-free seeds and establishing a new lawn. Before starting, use a power rake to lift thatch, break up aerator plugs, and loose the soil. Go over your yard from two directions, remove dead debris, and allow seeds to come to direct contact with the ground.
Then spread the precise amount of seeds around by using a broadcast spreader. In general, you will need approximately fifteen seeds per square inch (0.00065 m2).
Step 5. Water the soil
Water the new grass regularly. If it is possible, you should do it at least twice a week. Choose to do that job early in the morning to avoid the heat of the summer days.
Most yards need approximately 1.5 inches (3.8 cm) of water a week. How much water your lawn needs depends on the type of grass and the soil in your yard as well as the climate in the region you live in.
To precisely determine how often you need to water your lawn, you can use a few tests, including screwdriver test (pushing a screwdriver 6 inches (15 cm) into the soil to check if it is moist) or rolled grass (grayish, rolling leaf blades are the sign that your land is dry).
You can use an oscillating lawn sprinkler which can cover a waste area and prevent washing away grass seeds at the same time.
Step 6. Fertilizing the lawn
Let your lawn dry and spread weed-killing fertilizer over the new grass. To help the roots of your grass to develop appropriately, you should add a lawn fertilizer containing nitrogen, potassium, and phosphorus.
Keep in mind that some States don’t allow adding phosphorus due to water pollution concerns. Therefore, you need fertilizers labeled ‘New Lawns’ or ‘Starter.’
Take care to apply it in mid-spring and summer if you have warm-season grasses in your lawn, and during summer or early fall if grow cool-season grasses. That way, your grass will get all the necessary nutrients for healthy growth.
Give your new grass enough time to grow. After it becomes viable, you can start maintaining it.
Maybe you should invest in a seasonal treatment to help your lawn stay weed-free, green, and lush. Apply it once every three months, and you won’t need to spend time by fighting with weeds and re-seeding the new grass every spring.
Overseeding Weedy Lawn: Homeowners Take Back Their Yards
When you look out over your yard, does the sight you see bring you a sense of pleasure and pride, or do you cringe with embarrassment? If you’re in the latter camp due to unsightly weeds and patchy, lifeless grass, don’t despair—and don’t give up! Your yard doesn’t have to be the neighborhood eyesore, and you don’t have to declare your neglected lawn a total loss.
Depending on the severity of your situation, it’s possible that you’ll need to re-sod the entire area, but a far easier fix might work just as well. The simple yet highly effective key lies in overseeding weedy lawns to reclaim the lush, green, beautiful grass that all homeowners desire.
Let’s find out how just a bit of time, care and know-how will help you resuscitate your ailing lawn into a thing of emerald, weed-free beauty.
Overseed: Definition And Benefits
The term “overseed” may sound technical and even intimidating if you aren’t familiar with the process, but it’s really a simple gardening concept: Overseeding is simply the process of planting new grass seed over your existing grass in order to create a revived, newly green and beautiful lawn that is lush and healthy.
When you overseed your lawn, you build on its current strengths while working hand in hand with nature against its weaknesses. With a bit of elbow grease, the result is a lush, weed-free lawn that your neighbors will envy.
But how do you know if your yard is a good candidate for overseeding? Grass that is looking tired, patchy or weedy is prime for this relatively easy option for homeowners who want to help their yards recover. If weedy patches and bare spots make up less than half your lawn, overseeding is an excellent option for you. It is certainly easier and more cost-effective than digging up your entire yard and laying down all new sod, which can be an expensive and painstaking process.
Our Answer To The Common Question: When To Overseed My Lawn?
Many homeowners ask themselves, when is the best time of year to overseed my lawn? No matter which region of the country you call home, there are two times of year that are best for overseeding: early spring and late summer (mid-August to mid-September).
The spring option is best for homeowners who use non-organic fertilizer products containing chemicals that would stop new grass seeds from growing. By overseeding in early spring, you’ll give your existing grass and soil the most time possible to shed all the chemicals that could impede fresh growth.
If non-organic fertilizer use isn’t an issue for your yard, you might opt to overseed in late summer instead. This is generally the time of year when weeds grow the least, making it the best time to address weeds aggressively and effectively. This is also a great time of year to facilitate new grass growth before your turf goes dormant for the winter.
Why Do I Have Weeds In My Lawn In The First Place?
Before we get into the step-by-step process to overseed your lawn, it’s important to discuss how your grass got so weedy and patchy in the first place. After all, you don’t want to put in a lot of work just to have the same issues develop again in the future. So why do you have weeds in your lawn? How do these pesky, fast-growing plants move in and take over?
There are many factors that can contribute to a weedy lawn, including watering too much or too little, setting your mower blade too low, not mowing often enough or having a yard with poor drainage. Essentially, weeds are opportunistic; they grow when and where they can. Grass that is less than thriving provides the necessary space and opportunity for weeds to move in.
When weeds do begin to pop up here and there, chemical weed killers might appeal in the moment, but these products can actually be dangerous for people and animals, not to mention for your grass itself. Plus, if you aren’t careful, you’re likely to find yourself relying more and more often on weed killers to spot-treat your problem instead of resolving it at its source: by growing grass that is dense and vigorous.
The simple truth is that a thick, thriving lawn is the best weed deterrent on the market. Savvy homeowners know that keeping weeds away for good isn’t about finding the right herbicide product—it’s about keeping your grass dense, lush and green, so weeds don’t stand a fighting chance at taking over your lawn.
How To Overseed: The Step-By-Step Process, Explained
The first consideration, before you start overseeding your lawn, is choosing the right variety of grass seed. The best options are perennial varieties that will do well both in your geographical region as well as in your particular yard. If you have a yard with large trees and lots of shade, for example, a shade-tolerant variety like fescue might perform better than a different, sun-loving variety like Bermuda. Another thing to consider is how damp or dry your region is, and what type of drainage your yard has. If you live in a wet area or your yard tends to collect moisture, a grass like St. Augustine might fare better than it would in a hotter, drier or sunnier area.
Once you’ve chosen the right grass seed for your yard, it’s time to prep your existing lawn and soil for overseeding. Here are the easy, step-by-step instructions for overseeding your lawn:
- Before you start your overseeding project, it’s important to water your yard deeply. In the days leading up to when you plan to spread your new grass seed, give your lawn a good soaking, allowing water to penetrate up to six inches below the surface. This will give your turf a couple of days to dry out a bit before you begin overseeding.
- Pull up or otherwise remove any large weeds in your existing grass. Bigger weeds can simply be pulled up by hand, preferably from the roots. You can also use an herbicide if you choose; if so, just be sure to follow up with a second application three weeks later to ensure that any new weed growth is also killed off.
- Mow your existing grass. Using a collection bag attachment if your mower has one, mow your lawn as short as possible, preferably to about one and a half inches. Yes, this will make whatever healthy grass you have look bald and terrible for the moment—but don’t worry! There’s a method to the madness. Your new grass seeds are going to need access to sunlight and water as they take root and grow, so it’s very important to facilitate that by getting the existing grass as short as possible. Once you’ve finished mowing, rake up any leftover grass clippings and dispose of them in lawn bags.
- Remove thatch. Thatch is the criss-crossing layer of dead grass roots and stems that lies on top of the soil, just beneath the greener blades of grass. Thatch must be removed so that new grass seeds can reach the soil along with compost, fertilizer and water. In smaller yards, thatch can be removed effectively with a hand-held rake, but homeowners with larger yards may want to rent a power dethatcher from your local garden center to do the job. Also called power rakes or vertical mowers, these machines will leave clumps and piles of grass and thatch; be sure to rake debris up when you’re finished with this step and dispose of it in yard bags.
- Aerate your grass. You can rent an aerator from your local garden center or, if your yard is small (or you simply don’t like the loud noise and gasoline stench of an aerating machine), use a manual aerating tool. Be sure to rake up and dispose of any soil plugs that are dislodged as part of the aerating process.
- Spread a half-inch thick layer of compost over your lawn. Once you’ve got your compost spread evenly, rake it lightly so it can mix with the soil and blend into the aeration holes.
- Fertilize your grass. Grass fertilizers contain nitrogen, phosphorous and potassium—the three most important ingredients in a healthy lawn. You can use either a hand-held spreader for smaller yards or a drop spreader for larger ones to distribute your fertilizer evenly all over the yard.
- Apply grass seed. Using a hand-held broadcast spreader, apply your chosen grass seed over the entire lawn area. The goal is to have about 15 to 20 seeds per square inch, which typically results in several pounds of seed per 1,000 square feet of lawn. You can move in parallel lines as you spread the seed and then, if needed, go back over the area in perpendicular lines to ensure proper, even spreading.
- Use a rake to work the seed very lightly into the existing grass and soil. Be gentle—you don’t want to damage your seeds or interfere with their even distribution.
- Water generously, but not too much, and voilà—you’ve just overseeded your yard!
Over the next days and weeks as your grass begins coming in, be sure to water lightly once or twice a day, making sure the area doesn’t get sopping wet. This will give your lawn just the right amount of moisture until seedlings sprout. Let your new grass grow at least three to four inches before mowing for the first time. Once you’ve mowed the first time, you can switch to a deep-soaking watering pattern. To keep your grass its healthiest over time, be sure to fertilize twice every year, each spring and fall.

Overseeding Weedy Lawn—Waste of Time or Effective?
Anyone who’s had to care for a lawn of their own knows how easily weeds can spread. Once they get into your yard, it’s almost impossible to get them out, no matter the number of herbicides you use. That’s because weeds are opportunistic and will claim any bare or thin patch they can find in your yard. But is overseeding weedy lawn areas a good option? Or will the weeds just crowd out your new grass. I’ll discuss in today’s article.
The best way to get rid of weeds, oddly enough, is to grow a lawn lush enough to kick them out.
If weeds don’t have a place to grow, they’ll stay out of your yard.
One of the best ways to reclaim your yard is to periodically overseed it. Overseeding (or spreading grass seed on an established lawn to help it thicken up) is an effective way to improve your lawn, but it’s no quick fix.
It’ll take a good amount of work, but the results are worth the effort if done correctly.
Let’s talk about effectively overseeding weedy lawn areas and the best times of year to do so.
How Overseeding Can Help Your Lawn
Overseeding is the method of revitalizing a yard by adding more seed into an existing lawn.
You don’t have to till your lawn, and you don’t have to tear it up for over-seeding a lawn to be effective.
When you overseed new grass grows to fill in the bare spots of your yard, making it grow in greener and thicker.
Overseeding at the right time of year, before weeds are established or after annual weed pressure begins to ease, will ensure success.
How To Succeed When Overseeding Weedy Lawn Areas
The most important things with overseeding are preparation and timing.
You can’t overseed a weedy lawn in the summer when all of your weeds are mature and growing vigorously. You’ll be wasting your time and money if you try that.
The best times to overseed your lawn are early spring (when soil temperatures are consistently above 55 degreees Fahrenheit) and early-mid autumn.
The time of year when you overseed your weedy lawn will depend upon why you’re doing it in the first place.
If your lawn is thin, and you want it to grow in thicker to prevent weeds from growing, early spring is your better bet.
If you want to give your lawn a hard reset, late autumn is the better choice as your new grass will not have any pressure from annual weeds.
The hot summer months are very harsh for new grass seedlings, so springtime isn’t quite as good for most weedy lawns.
Preparing Your Lawn for Success
Aside from choosing the best time, you must prepare your lawn for overseeding to work the best.
- Cut your grass short. When mowing your lawn normally, you should only cut it by 1/3 its length. But for overseeding, you want the grass short enough to make sure grass seed can get close to the surface. Try cutting the grass by 2/3 its lengths or cut it down to about 1 ½-inches tall.
- Clear your lawn of clippings. After mowing your lawn, make sure there are no clippings on your yard. These can interfere with new grass seed. Either use a bag on your mower or rake them up afterwards.
- Let air into your yard. You want to then loosen up the soil to improve soil contact with the new seeds. This is also a good time to remove thatch from your yard. Either aerate your lawn or use an iron rake to loosen the turf.
Seeding your Lawn
Once these steps are done, it’s time to spread seed onto your yard.
First, choose a grass seed that matches your climate and pairs with your grasses. Also, pick a grass that you can depend on. You want it to grow through the year, and be able to adapt to your yard conditions, like if your yard is sunny or shaded.
Before you begin spreading seed, check the label on the grass seed you purchase for the rate of overseeding. Most bags of grass seed will provide this information right on the bag.
You want to get the right amount of seed in your yard—too much will keep grass from growing because the seedlings compete for moisture, too little and your yard will stay thin and ripe for weed growth.
Once you’ve determined your application rate, use a lawn spreader (broadcast spreaders are my preference) to evenly spread it over your yard, and make sure you spread it on a dry day with no wind.
I like to spread some quick-release starter fertilizer on the lawn before spreading my seed. Scott’s makes a really good product (Amazon link), and it’s particularly good for Spring overseeding because it has a crabgrass preventer in the mix.
Spreading a thin (1/4 inch) layer of compost over the new seed will work wonders to improve germination and help your new seedlings thrive.
You’ll probably want to review my guide to watering new grass to improve your results.
Maintaining Your New Grass
Watering your new grass is critical and knowing the stages of watering is very important.
New grass needs a lot of water, and you want your soil to stay constantly moist.
For new grass, water lightly twice per day for the first week, and water more heavily the second week.
After 2 weeks, water heavily and less frequently. You want the soil saturated down to 6-inches each time you water it past the 2 week point. This will encourage your grass seedlings to grow deep roots which will improve your lawn’s resilience to heat and drought.
Wait several weeks before mowing your lawn.
Make sure the grass is over 3 inches (I recommend 4-inches in height for the first mow), otherwise you risk ripping your seedlings out of the turf because their roots won’t be deep enough yet.
When you do mow, bag your grass clippings the first few times, and adjust your mowing deck to cut no more than 1/3 of the grass blade.
Similarly avoid herbicides for several weeks on new grass.
If you used starter fertilizer, I recommend throwing down organic slow-release fertilizer after 4-6 weeks to sustain and feed your new lawn and keep it healthy.
Annually overseeding weedy lawn areas in combination with the use of pre-emergents every spring will gradually transform your weedy yard into the lush green carpet every homeowner wants.
