DIY Hydroseeding Your Lawn at Home

Hydroseeding may appear to be high-tech and complicated, yet it is so easy that you may conduct it in your own lawn. It’s a way of seeding a lawn that’s proving to be so effective that it’s beginning to supplant older methods like sodding and broadcasting.

We’ll walk you through the whole hydroseeding process, including how to hydroseed your lawn and how to care for it afterward, in our comprehensive DIY hydroseeding guide.

What Is Hydroseeding?

Spraying grass seed combined with water onto a specified area is known as hydroseeding. Fertilizer, mulch, and other additions may be used in the mix to aid seed germination.

Hydroseeding is a technique for controlling weed growth, beautifying yards, and preventing dust pollution and erosion.

According to Green Tech, labor expenses are cheaper for hydroseeding than for laying sod since the procedure is very easy and straight-forward. Furthermore, hydroseeding takes minimal time, has a high germination rate, and produces high-quality grass.

The Hydroseeding Process

Simply simply, hydroseeding is a technique for growing grass and preventing soil erosion by spreading a specific grass “slurry” uniformly across bare land. Grass seeds, mulch, water, fertilizer, biostimulants, and occasionally green-tinted dye make up this slurry.

The fertilizer promotes development, while the mulch binds the seeds to the soil, shields them from the elements (such as wind or excessive sunlight), and eventually gives extra nutrients as it decomposes on the growing grass.

Hydroseeding is also known as hydraulic mulch seeding or hydromulching. If you’ve never heard of hydroseeding or any of its other names, it could seem a little strange. However, it’s a tried-and-true method that’s been around for more than half a century.

Pros & Cons of Hydroseeding

✔ Seed mixtures that may be customized
✔ More effective method of sowing than traditional seeding
✔ Unlike putting sod or typical seeding, this method creates a more uniform appearance.
✘ Initially needs a lot of watering
✘ Hydroseeding is less effective than sod or regular seeding when done at home.

Doing your own Hydroseeding is far less expensive and time-consuming than using other methods, especially if you have a big area of your yard to seed.

If traveling over the entire yard isn’t necessary, this procedure may be utilized to ‘patch up’ spots where the grass is thinning, and fixing up any areas you may have missed is simple. However, if you only have a little piece of land to work with and want to make your own hydroseeding grass, it might not be worth the hassle to gather everything you’ll need.

Because the seeds are combined with nutrients before being sprayed, they sprout considerably faster, and the grass’s germination rate is aided by the short soaking in the water while it is being sprayed.

However, because this approach includes sprinkling the seeds on the ground’s surface, they will rapidly dry up if they are not watered at least twice a day, every day for a week or more while the grass is establishing.

Depending on how much money you want to save, you may buy individual pieces and put them together yourself, buy a ready-made kit, or rent a set of do-it-yourself hydroseeding equipment in some regions.

Whatever, the products you want may not be available in your region, requiring you to drive vast distances or special order certain seeds or mulches and wait however long it takes for the materials to arrive.

Hydroseeding Vs. Sod

Sod planting is a fantastic approach to achieve immediate results: The patched area seems full straight away, and the sod may be walked on right away after installation. However, that instant gratification installation comes at a great cost. Hydroseeding is the next best thing if hand-seeding isn’t working and you don’t want to spend the money for sod. Although you can’t walk on the patched area for a longer period of time, this procedure is in the center of the price range—and it grows quicker than hand-seeded grass.

Basics Of Hydroseeding

In terms of cost, labor, and growth rate, hydroseeding is the middle-of-the-road option. Once established, though, you could argue that hydroseeded lawns are the most appealing. Seeded lawns have a tendency to develop in patches, while sod lawns may have apparent “seams” or gaps. Meanwhile, hydroseeding uniformly distributes the slurry for a more uniform appearance.

Hydroseeding Supplies

It’s usually a good idea to test your soil before consulting with a professional so that they can assist you choose the right blend for your yard. You may get hydroseeding mulch online or at home stores to build your own combination if you rent equipment for DIY hydroseeding your grass.

Home Hydroseeding

Hydroseeding, also known as hydraulic mulch seeding or hydro mulching, is a technique for sowing grass or other seeds in an area by spraying a seed mixture over it. When done correctly and under the right circumstances, the technique can be more efficient and cost-effective than traditional, time-consuming approaches like tilling the soil to prepare it for planting.

One of the most significant advantages of hydroseeding is the time savings. If you have a pretty wide area to plant or if, for example, you want your seeds to sprout before the winter weather arrives, you might want to consider it for your own landscaping project.

Because the seeds have been enriched with extra nutrients in the unique hydroseed combination, they can sprout in as little as a week. That’s a lot less time than the traditional hand-seeding technique, which can take three to four weeks.

Another benefit of spray-on grass seed is that it is relatively easy to disperse over uneven regions, resulting in healthier, less eroded, and more equal planting than conventional seeding would give in locations such as hills and rocky terrains.

DIY hydroseeding is also a cost-effective option. Doing your own hydroseeding can save you hundreds of dollars because you won’t have to pay for labor or landscapers.

Do It Yourself Hydroseeding Costs

Hydroseeding is a simple way to have a lovely lush lawn of green grass for a fraction of the expense of sod installation. However, this does not imply that you can get everything you need for pennies on the dollar.

You can either buy a kit that includes everything you need, or you can go out and buy each ingredient separately, presumably in the correct proportions so that you don’t have any leftovers.

The equipment you’ll need to spray your mix is likely the most expensive part of your do-it-yourself hydroseeding budget. Renting one for a day may cost about $300, and buying one for less than $1,000.

While making your own container with the correct size hose, special nozzle, pump, and agitator is less expensive, it may still cost over $700, but you may be able to accomplish it for less if you already have some of the materials needed.

Who Should Try Hydroseeding?

Hydroseeding is a solution that is used in locations that are deemed troublesome. This is especially true in locations that are susceptible to erosion. However, you can apply this approach on almost any lawn and get fantastic results. We recommend it for bigger lawns that might otherwise take a long time to seed.

Is Hydroseeding Better Than Laying Sod?

It’s all up to you. Using a hydroseeding approach on bigger lawns tends to produce equal (or better) outcomes at a fraction of the cost. After all, sod isn’t exactly cheap. However, one advantage of sod is that it provides you with a lawn right away. Sod may be a better option if you need results quickly and can’t wait.

What Do You Need In Order To Hydroseed Your Lawn?

Hydroseed Your Lawn

Hydroseeding your lawn is a labor-intensive procedure, at least in terms of equipment. What you’ll need is the following:

Grass Seeds – We highly advise that you select your seeds carefully. You’ll want to choose grass seeds that are suitable for growing in your area and are engineered to sprout during the growth season. It’s a good idea to inquire about which grasses are excellent for hydroseeding at your local lawncare business.

Water – That puts the “hydro” in hydroseeding.

Fiber and paper mulches perform well as a hydroseeding/regular mulch. You can pick a green-dyed mulch if you wish to. This helps you distinguish where you’ve sprayed and reduces the eyesore that is a brown area of crap.

Fertilizer – Milogranite is effective, but you should also seek for fertilizers that can assist grass growth at all phases of development, particularly with a time-release function.

Compost – We’ll presume you have a compost pile already.

Topsoil – For soil preparation, this is a requirement.

How To Hydroseed Your Lawn: The Step-By-Step Guide

The following stages are involved in hydroseeding, whether you do it yourself or employ a professional. Hydroseeding should be done between March and October for the greatest effects.

1. Choose Your Seeds.

Unlike putting sod, hydroseeding allows you to create a bespoke grass blend made up of many species, each with its own set of benefits. The weather where you live should be your starting point. Then you may choose your mix according on the traits you want, like as heat resistance, disease resistance, or drought resistance.

If you’re hydroseeding, ask your local garden shop which grass combination will work best for you. If you employ a professional, they will be able to help you through the process and give the right mix for you.

2. Conduct A Soil Analysis

Whatever form of seeding you pick, soil testing are essential. Make sure your soil has the proper pH—it shouldn’t be too acidic or too alkaline. A soil pH of 6.5 to 7 is ideal for most grasses. Depending on the level of your soil pH, you can alter it using lime supplements, organic material, or sulfur.

If you want to do it yourself, you may buy a commercial test or an at-home kit and then submit a sample to a corporation or institution for analysis. The test can also be done by the professional lawn care business you employ to hydroseed your grass.

3. Clear Off The Ground

Unlike sod, hydroseeding should only be done on bare soil. Remove any weeds and rubbish to give your lawn a fresh start.

4. Grade The Soil

Next, make a grade that is 2.5 to 3 inches lower than the end grade you desire. This will prevent the slurry from getting into your house or any other structures, where it might cause moisture damage.

5. Apply Topsoil And Compost

To get things started, spread a 2-inch layer of dirt and compost on your grass to provide it with the nutrients it needs to grow strong and lush.

6. Re-Grade The Soil

Take the time to re-grade your soil and make sure it’s perfectly smooth. It’s preferable if the surface is as smooth as possible.

7. Prep The Hydroseeder

To get a properly mixed slurry, add your specific blend to your hydroseeder and turn on the agitator. The greatest, commercial-grade hydroseeders are available from professional lawn care firms, but you may rent or buy your own.

8. Spray

Finally, the enjoyable part. With your hydraulic equipment, spray the hydroseed across the earth.

9. Next Steps

After then, it’s all about upkeep. You’ll need to pay extra attention to keeping your grass wet for the first two months after hydroseeding. Watering two to three times a day for the first few weeks is critical, and then watering less (but more than normal) for the next six to seven weeks is optional. It’s critical that no one walks on the lawn during this period, including children and pets.

Depending on the grass variety, you can observe grass emerging in as little as seven to ten days after hydroseeding (for instance, rye grass will germinate faster than Bluegrass). After four weeks, you may begin mowing.

How Hydroseeding Compares To Other Methods

Sod installation, conventional seeding, and hydroseeding each have their own set of advantages and disadvantages. Before we look into hydroseeding, let’s take a look at laying sod and conventional seeding.


Sod is the quickest and most expensive way to get a grass started. S od pallets are 70% more expensive than hydroseeding—a lawn built with sod may cost up to $10,000, whereas hydroseeding the same size lawn would cost between $2,500 and $5,000, including the expense of employing a contractor.

The obvious advantage of sod is that it is fully grown, built-in grass that you can instantly dig your toes into following installation. You may lay sod at any time of year, but the best period is late spring to late summer. Sod doesn’t require a lot of upkeep or irrigation. In most cases, sod takes a few weeks to establish itself in a lawn.

The disadvantages of sod include its expensive cost, restricted grass seed alternatives, and the possibility of being unhealthy. Sod is less hardy than a lawn whose seeds are sown directly in the soil from the start since it is grown, then cut and installed.


Traditional seeding is the most affordable option, generally costing less than $1,000 for a lawn that would cost $2,000 to $5,000 if hydroseeding was used. However, this process takes longer than hydroseeding, and it takes the longest to see results, since a conventionally seeded grass can take up to six to ten weeks to properly establish and be ready to bear foot activity. Whether you reside in a cool grass, warm grass, or transition zone determines when you should seed your lawn.

Seeding’s largest advantage is its low cost, while its biggest disadvantage is the time it takes for seeds to germinate.

While hydroseeding is less expensive than laying sod, it is most cost-effective on bigger lawns because the set-up and equipment costs the same for a smaller lawn—despite the fact that you’ll require less hydroseeding overall.

How Should You Choose Your Hydroseed Blend?

This is a complicated subject, but it all boils down to the demands of your grass. You must decide whether your lawn need a special fertilizer, extra mulch, or any other “goodies” in order for it to thrive. If you’re stumped when it comes to establishing a hydroseeding blend, we recommend speaking with a sales representative at a lawncare business.

How Soon Should You See Results With Hydroseeding?

“Planting on steroids” is a nice way to describe hydroseeding. This method can result in your seeds sprouting in as little as a week, while some seeds may take 10 days or longer to germinate. Within four weeks of a hydroseeding treatment, most customers will be able to mow their grass.

Is It Safe to Use Weed Killer on a Newly Hydroseeded Lawn?

Though hydroseeding is known for producing high-quality, resilient grasses, it isn’t a miracle worker. Weed killers (such as those sold in stores) are extremely strong chemicals. They can and will harm seeds that have only just sprouted, which is why you should never spray them on a newly planted grass.

You should wait until your grass has been mowed at least twice before applying weed killer. This is just a decent rule of thumb to follow in general.

Is It Necessary To Hydroseed Your Lawn?

It’s entirely up to you how much work you want to put in. Hydroseeding is a difficult process, especially when it comes to soil preparation and mix preparation. It is, however, very possible if you have your heart set on it. As far as DIY projects go, this is a simple to moderate effort that might save you a lot of money if you do it yourself.

Although you may do it yourself and get decent results, most people choose to employ a professional team. The explanation for this is self-evident: the workload.

How To Maintain Your Hydroseeding Lawn

Maintain Hydroseeding Lawn

Congratulations if you’ve gone out and hydroseeded your grass. That’s a huge step in the right direction for the health of your grass. The difficult part, on the other hand, had just just begun. Here’s how you’ll have to keep your grass in good shape:

You should water your grass at least twice a day for the first month following seeding. For this, we recommend installing automatic sprinklers. If you reside in a dry climate (such as Nevada), you’ll need to water your grass three times every day.

You can reduce your grass watering to once a day after five weeks. Your sprouting seeds will require less water than the ones that were having trouble germinating. So, when this period of time has passed, you may begin to slow it down.

When your seeds are fully developed, you may begin watering them on a more regular basis. Depending on the grass breed you selected, fully grown grass can survive being watered two to three times each week.

After six weeks, apply another round of fertilizer to your lawn to keep it looking lush for weeks. This helps to increase the nutrients in your lawn. For this round and following rounds, we recommend using a nitrogen-rich fertilizer.

Things To Consider

Although there are several advantages to home hydroseeding, there are some crucial factors to consider before getting started. To guarantee that the mulch and plants stay healthy and flourish after hydroseeding, they must be kept wet at all times. You may need to water it three times a day during the first two weeks of development, then at least once a day for the next two weeks, depending on your environment. If you reside in a dry climate, you might want to try an alternative planting method.

Furthermore, if you reside in a remote region, you may need to drive considerable distances to numerous stores to obtain all of the necessary materials for your customized hydroseed combination. If you have a tiny backyard that doesn’t need a lot of time to seed traditionally, it might not be worth the bother.

Frequently Asked Questions

Is Topsoil Truly Required For Hydroseeding?

If you want to hydroseed your grass, you don’t technically need topsoil. However, the majority of people will be disappointed with their outcomes. In fact, without it, there’s a significant risk your grass won’t be able to properly develop. It’s preferable to operate as though you require the topsoil rather of risking unsatisfactory outcomes.

When is The Ideal Time To Seed Your Lawn Using Hydroseed?

Hydroseeding is best done in the early spring and early autumn, while it may be done during any of the more typical landscaping months. Both seasons provide warm soil and mild to moderate rain, making them perfect for establishing new grass and caring for your lawn.

If you choose to hydroseed your lawn in the summer, keep in mind that the heat of the sun may both assist and injure your grass. High UV radiation may cause your soil to dry up more quickly. If you want to cultivate your seeds in the heat of summer, be sure to water your grass a couple of times more every week.

Is Walking On a Hydroseeded Area Considered Acceptable?

Although it isn’t ideal, you should be able to get by for the most part. Just walk as little as possible and only when absolutely essential.
