Scotts Thick’R Lawn Review

The Scotts Thick’R Lawn offers a 3-in-one solution for thin lawns. First, it has a seed improver that helps fill gaps within your current lawn. Next, it has a fertilizer improver that aids in keeping the lawn green. Third, it uses a soil improver for enhanced root development. With these three features, your lawn can become 50% thicker after application. 

This fertilizer is used for newer lawns that are still in development. One way to measure its effectiveness is to look at the treated and untreated areas of your lawn. The treated areas will appear fuller and darker, with taller grass. For untreated areas, continue to reapply Scotts Thick’R Lawn until the grass shows noticeable results. 

Users like the Scotts Thick’R Lawn because of its 9-1-1 NPK analysis. This means it contains 9% nitrogen, 1% phosphorous, and 1% potassium. With these three ingredients, you’ll have a greener and more energized garden. 

When using the Scotts Thick’R Lawn, water your lawn for an hour a day after it’s been applied. This will aid in helping your plants and grass grow faster while allowing the fertilizer to get ingrained in the soil. If your grass is in the seeding phase, you can use a sprinkler to water it every other day for 7-10 days. This gives your grass enough time to grow properly.

Additionally, the Scotts Thick’R Lawn can be used for medium to large size lawns. It has a coverage area of 4,000 square feet, which is more than enough to get your lawn in good health. Once applied, the fertilizer will start to improve the soil by letting it absorb its nutrients. 

To get the best results, water the grass twice a day for three weeks. This keeps the soil surface moist after the seeding phase. You can set up auto timers to ensure that no essential lawn watering sessions are missed. Once the grass is at 2-3 inches in height, you can mow the grass so that it remains even.

For added lawn maintenance, use a dethatcher to remove thatch hidden underneath the soil. Then you’ll want to spread the seed and use the back of the rake to cover it up. By doing this, you’ll increase the efficiency of the fertilizer and impact your garden’s growth rate.

Overall, the Scotts Thick’R Lawn is the best product for those wanting to revitalize their garden. It is an all-in-one solution for thin lawns and existing lawns because of its enhanced root development. By getting this product, you’ll be able to fix empty patches in your lawn and turn them into healthy green grass.

How To Apply Scotts Thick’R Lawn

First, prepare by mowing the area to a height that’s 2 inches or at the lowest mowing setting. With a dethatcher or a rake, loosen up the soil’s top layer and remove any additional debris. Spring and fall are the best seasons to apply Scotts Thick’R Lawn as these are the periods that experience most lawn growth. When applying, make sure the environment is between 60°F – 80°F to get the best results.

Next, you’ll want to use the Scotts Spreader to aid in spreading it evenly throughout your lawn. Walk slowly when using the spreader to ensure that the fertilizer reaches all areas. By doing this, you’ll increase the chances of thickening your grass and improving your garden. 

Third, you’ll need to water the soil often after the Scotts Thick’R Lawn has been applied. This allows the soil to remain moist and work well with the fertilizer. When using this product, always check your soil often to see if any changes have occurred.

How does Scotts Thick’R Lawn work?

Scotts Thick’R Lawn works in 3 ways:

  • Seed: The seed feature is used to fill in gaps in your lawn. For instance, if you notice any open areas with little grass, the seed will work by helping them grow. 
  • Fertilizer: The fertilizer aids in making the turf and grass green. When applying this fertilizer, make sure that it is evenly spread or else certain areas will show more signs of growth than others. 
  • Soil Improver: Tired of having weak soil? The Scotts Thick’R Lawn reaches deep within the soil to aid it in plant growth. Through these 3 methods, you’ll have a  surefire system that will keep your garden healthy. 

When Should You Apply Scotts Thick’R Lawn?

You should apply the Scotts Thick’R Lawn fertilizer once in the spring and once in the early summer/fall season. This allows the plants to grow naturally and maintain the soil when the season changes. 

Only apply this fertilizer on growing turf. Avoid applying this product on drain ditches; storm drains or near water. If heavy rain is expected, wait until the ground dries up before applying. Apply the fertilizer on your lawn and sweep any excess remains that lands on the street or sidewalk back onto the lawn. 

How Long Does It Take For Scotts Thick’R Lawn to start?

On average, it takes about 30 days for the Scotts Thick’R Lawn to start filling in. After week 6, you’ll notice your grass starting to become thicker in density and volume. 

The quality of the results will depend on how you applied the fertilizer. For example, if you don’t see any growth within 2-4 weeks, that is a sign that you should reapply the Scotts Thick’R Lawn to these areas. 

The first indicator of the fertilizer’s effectiveness is by viewing the untreated area of your lawn. If you notice any ungrown areas, you can lightly apply a small amount of fertilizer in that area. Thus, making it easier for your garden to grow in the long term.
