Spray on Grass Seed For Your Lawn

Do you want a lush, green lawn but don’t have the time to water and care for it? Spray on grass seeds may be the solution for you. It is also known as hydroseeding. This allows you to grow a beautiful lawn in just a few short minutes of work. Spray on grass seed is made up of tiny seeds that attach to your existing lawn. Once the seeds take root, they will start to grow and fill in any bald spots or patches in your yard.

While many homeowners have recently turned to using artificial turf on their lawns over natural grass, many are still more at ease with the thought of growing their own grass from seed. It is not surprising why. Plants grown from seeds are happy, mature plants that have been nurtured and raised by hand, ultimately making them deal with less stress once they transition into the natural environment of their surroundings. If you live in a new home or are planning to renovate your lawn and make it appear as if it had just been seeded naturally, finding out how spray-on grass works and deciding whether this method of re-sodding your lawn is right for you can be very rewarding.

What is spray on grass seed?

Spray on grass seed is a lawn seeding product that can be used to repair bald spots or thinning areas in your yard. It comes as a liquid that you spray onto an area that needs coverage.

Spray on grass seed is an innovative lawn care product that has been designed to provide homeowners with a low-cost way to protect their lawns and gardens from the ravages of drought, insects, and weeds.

It is remarkably simple to use and requires no mixing or expensive equipment; just spray it on your lawn and let it dry.

Spray on grass seed’s active ingredient, systemic chitinase enzyme, breaks down weed seeds as well as the root structure when applied directly to the lawn, thus preventing future weeds from sprouting up in the same area. It prevents most broadleaf weeds within its reach from germinating, which essentially makes it a broad-spectrum weed killer.

The best time to use spray on grass seeds is during late summer or early fall when the temperatures are still warm but there is not too much rain in the forecast. This allows the seeds enough time to germinate and take hold before winter sets in.

What to consider when using spray on grass seed

When using spray on grass seed, it is important to keep these things in mind:

  • Make sure you have even coverage. Spray the product onto the area that needs coverage and then use a broom or rake to help spread the seeds around.
  • Keep an eye on your lawn for the first few weeks after seeding. If you see any areas where the grass is not growing, go back and re-seed those spots.
  • Water your lawn regularly, especially during hot weather periods. Newly seeded lawns need at least an inch of water per week to stay healthy.


Why do you need spray on grass seed?

How does spray on grass seed work?

The grass seed in the spray mixture is designed to stick to the soil and start germinating immediately. The seeds are then covered with mulch that helps protect them from birds, rodents, and other animals, as well as wind and rain.

Know your grass seed

Not all grass seed is created equal. You need to make sure you are using the right type of grass seed for your climate and soil conditions. In general, there are three types of grass seed: cool season, warm season, and transitional.

Cool-season grasses include Kentucky bluegrass, fescue, rye, and bentgrass. They do well in cooler climates with moist soils. Warm-season grasses like Bermuda, St. Augustine, zoysia, and buffalo thrive in hot climates with dry soils. Transitional can grow in either cool or warm climates but don’t always have the best drought tolerance or winter hardiness.

If you are not sure what type of grass you have or what kind of seed to use, take a sample of your lawn to a local garden center or home improvement store and they will be able to help you. You can’t spray on grass seeds that you can’t tell apart.

Soil considerations

The type of soil you have is just as important as the grass seed. Spray-on grass seed works best on soils that are not too sandy or clayey, but loamy and well-drained. Spray on lawn aerator if your soil is heavy with clay, this will help loosen it up and make it easier for roots to penetrate deep into the ground where they can access nutrients like nitrogen, phosphorus, and potassium that are essential for healthy growth.

Equipment considerations

You will need to get yourself a sprayer, but the type of sprayer you use depends on how much grass seed needs to be sprayed. If you are doing just one small area then handheld backpack-style sprayers work great for this purpose because they allow for quick application without having to move around too much or carry heavy equipment.

If you are spraying a large area, then it would make more sense to get yourself something like a boom sprayer that can cover much more ground in less time while still providing the same amount of coverage. Spray on grass seed will be easier if you have the right equipment.

If you don’t feel comfortable using any type of machinery with chemicals or sprays, then you can always get a professional to do the job for you. Just be sure to ask them about their experience using spray-on grass seed and what type of equipment they will be using.

Mowing and watering considerations

Once the spray-on grass seed has been applied, you will need to keep the area moist for about two weeks until the seeds have germinated. After that, it is important to continue to water your lawn regularly, but not too much or you will drown the new seedlings. You should also avoid mowing the lawn for at least two months after seeding to give them enough time to grow into strong plants that can withstand regular maintenance. For best results, spray on grass seeds and water them well.

Soil sterilization and weed control

Spraying on grass seed can also help with soil sterilization. Spray-on grass seed is applied to kill off any existing weeds or pests that may be living there before planting new seeds for next year’s crop of flowers or vegetables. It works by killing off these unwanted organisms without harming the beneficial bacteria, fungi, worms, and other organisms that help maintain healthy soil conditions for plant growth. Spray on grass seeds so you can grow plants without worrying about weeds or pests.

  • Prevents seeds from being washed away by rain and wind
  • Makes the process of growing grass much easier for those who don’t have green thumbs.
  • Spray on grass seed is also preferable because it helps prevent soil erosion.
