One of the most well-known fertilizer brands is Scotts Turf Builder, which is one of their most effective fertilizers.

This lawn fertilizer helps your grass grow larger roots, lowering the quantity of watering needed to keep it alive.

Because it includes a lot of nitrogen, this fertilizer immediately produces a lot of higher growth. It can be used on both warm and cool-season types of grass. The latter, on the other hand, should be handled with greater caution.

Because it contains no phosphorus and a lot of nitrogen, it’s the best fertilizer for older lawns. It has a 32-0-4 NPK ratio, which encourages quick, dense greening and strong root multiplication while preparing for a hot summer and a hard winter.

Pros

  • It is cost-effective and fits within your budget.
  • It contains no phosphorus.
  • Grass will need to be fed less frequently.

Cons

  • To use this fertilizer, you’ll need a spreader.
  • It will burn your lawn if not applied properly.

4-GreenView Lawn Food

  • Restores nutrients to the soil
  • Speeds root growth to improve nutrient absorption and helps lawns retain water to protect against drought
  • Features both immediate release and time-released nitrogen provides continuous feeding for up to 8 weeks
  • Can be applied anytime the turf is actively growing
  • Covers 15,000 sq ft
  • GreenView Yard Wide Guarantee - Your Satisfaction Guaranteed Or Your Money Back

GreenView Lawn Food is another excellent alternative for older lawns. It has an NPK of 22-0-4. It contains a lot of nitrogen, therefore it will aid in the growth of current grass.

If you want to bulk up your grass, this is an excellent way to do so. However, because it lacks phosphorus, it isn’t suitable for new growth.

It can, however, accelerate root growth. If you live in a region where the winters are extremely harsh, this can be a terrific way to extend the life of your plants.

It provides plants with a high level of endurance, allowing them to tolerate frigid temperatures. It also helps plants retain water, so if you live in a dry environment, it could be a good choice.

The fact that GreenView is time-released is also noteworthy. That means your grass will benefit not just at the time of application, but throughout the next few weeks as well.

If you’re seeking a low-maintenance, long-lasting fertilizer, this could be the answer.

Pros

  • To strengthen, use a super-speed-root recipe.
  • Great for building strong, cold-resistant grass at the end of the season.
  • Excellent for usage in locations where there is a lot of droughts.

Cons

  • Burning may occur if not applied with plenty of water.
  • It’s possible that not all weeds will be killed.
  • Spray food isn’t as effective.

8 steps to get a thicker lawn

1. OVERSEED

Overseeding is the process of putting grass seed into existing grass in order to thicken thin lawns or prevent them from becoming thin. New grass fills in the gaps between the existing grass, giving it a thicker, lusher feel and appearance.

Overseeding on a regular basis is the key to a beautiful lawn. Cool-season northern lawns should be overseeded in the fall and spring, while thin warm-season southern lawns should be seeded in the late spring.

Overseeding is a great way to increase the condition of your grass and make it thicker. You’ll get exceptional performance from grass kinds produced via industry-leading grass seed research when you use premium grass seed like Pennington Smart Seed.

Always choose a grass that is suitable for your grass-growing region, climate, and lawn conditions. If you’re growing grass in the shade, for example, shade-tolerant grasses can help you achieve the dense grass you want.

2. FERTILIZE

Lawn grasses, like other plants, require nutrition, yet minerals in the soil are frequently washed away by rainfall and irrigation. Fertilizing your grass on a regular basis throughout the growing season helps to offer the nutrients it requires for thicker, healthier growth.

When overseeding your lawn, a starter fertilizer like Pennington UltraGreen Starter Fertilizer 22-23-4 aids in the rapid establishment of new grasses by promoting powerful root growth. 

Pennington Ultragreen Lawn Fertilizer 30-0-4 offers the nitrogen your lawn requires for the thick, green grass in established lawns.

For up to three months, half of the nitrogen in these particular formulas slowly releases to keep nourishing your thickening lawn.

To prevent leaching, the other half is stabilized. This means less fertilizer is wasted on the environment, and the nutrients in the fertilizer you apply reach your thick lawn more effectively.

3. SOIL IMPROVEMENT

Take a suggestion from the pros and test your soil to get the most out of every step toward a thicker grass. Soil testing is a simple procedure that pays off handsomely in the form of thick, healthy grass growth.

A soil test provides you with a precise starting point for your lawn’s specific requirements, as well as recommendations for addressing any underlying issues. Contact your local extension office if you’re new to testing. They can help you get started with simple kits and information.

The pH of your soil and other soil characteristics that can stifle thick, robust growth is revealed through testing. You may improve your soil without guesswork by following test Recommendations.

Your grass, for example, will not be able to absorb nutrients if the pH of the soil is too low. Testing determines whether your lawn requires lime or other soil additions to restore pH balance and nutrient availability, allowing grass to thrive.

4. IRRIGATE

Once your thicker grass has established itself, maintain good lawn watering methods to ensure that it receives enough water and remains thick and robust. Grass seedlings need continual moisture to germinate and fill in gaps between existing grass.

Once established, lawns require around 1 inch of water per week, whether from the rain or through your irrigation system. Irrigation that is deep and thorough stimulates the deep root growth that bigger lawns require.

Pennington Smart Seed grasses conserve water, allowing your lawn to endure heat, drought, and other stressors that cause typical grasses to struggle and thin. Smart Seed uses up to 30% less water than regular grass seed, year after year, for the life of your lawn.

These exceptional, drought-tolerant grasses will stay green for up to three weeks without water, requiring less maintenance and maintaining the appearance of your lawn.

5. MPROVE YOUR LAWN

Take the all-in-one approach to get a thicker grass faster by combining the previous three stages into one simple, do-it-yourself lawn boost. Pennington Lawn Booster is a one-stop-shop for seed, fertilizer, and soil enhancers.

To promote seed germination and the overall texture and color of your grass, use Lawn Booster, which includes lime-enhanced, drought-tolerant Smart Seed and a professional-grade fertilizer. The nitrogen-stabilized fertilizer feeds your grass soon after planting and for up to eight weeks. Furthermore, the soil-enhancing gypsum in this product increases the health and condition of your soil without influencing the pH, allowing your grass to take root and flourish.

Boosting your lawn with Lawn Booster is as easy as three steps: Prepare the area, apply the all-in-one product, and water as directed on the packaging. In only one application, your lawn will grow faster, thicker, and greener than regular grass seed—guaranteed.

6. WEED CONTROL

Weeds compete for sunlight, water, and nutrients with grass. When you have a lot of weeds, your lawn gets less fertilizer and other nutrients. Weed control eliminates competition, allowing grass to remain thick and well-nourished. Killing common lawn weeds in the early fall is a great idea.

A pre-emergent herbicide used before the emergence of weeds in the spring can help your lawn grow thicker and lusher. Pennington UltraGreen Crabgrass Preventer Plus Lawn Fertilizer 30-0-4 feeds your lawn while also controlling crabgrass and broadleaf weeds.

Before they wreak havoc on your lawn’s thick, healthy growth. When overseeding your lawn, never use pre-emergent weed killers. Pre-emergents prevent all seeds from germinating and emerging correctly, including grass.

You can achieve a thick, lush lawn and keep it that way by incorporating these procedures and best practices into weekly lawn maintenance or short weekend lawn revamps. In addition, there are sporadic chores.

7. MOW IN THE RIGHT MANNER

Using proper mowing techniques allows your grass to grow thick and stay that way. Rather than mowing according to your weekly calendar, mow based on the demands of the grass. Mow your grass frequently enough to keep it at the optimum mowing height without eliminating more than one-third of it in a single mowing. Many of the stressors that generate thin, unsightly lawns can be avoided by doing so.

Make sure your mower is well-maintained so that the blades cut cleanly rather than tearing at the grass. Ragged, ripped grass is more prone to common lawn illnesses and insect pests, preventing lush, thick growth in your lawn. Changing your mowing pattern on a regular basis also aids in keeping the grass straight and thick.

8. Properly Water Grass

Your grass, like other plants, requires water. Grass requires the appropriate amount of water at the appropriate times.

Excess humidity can be created by watering at night, which is a recipe for turf disease development. When watering in the middle of the day, the water may evaporate too quickly before reaching the roots. As a result, the optimal time is early in the morning, right before or during sunrise. This allows the grassroots to absorb the water, and as the sun rises, it will burn off any excess water remaining on the grass blades, preventing illness from developing overnight.

The idea is to water less frequently and for a longer period of time so that your lawn gets a good soak rather than repeated shallow waterings. It’s a good idea to water once or twice a week, especially if Mother Nature isn’t already supplying regular rains. 

Conclusion

Your lawn will benefit the most from fertilizer if you follow best practices for growing particular types of lawn grass and maintaining quality.

Miracle-Gro Water Soluble Lawn Food Only uses starter fertilizers on new seedlings, plugs, or sod. Early in the spring, before the crabgrass seed regrows, crabgrass-preventing fertilizers are administered.

Weed and feed fertilizers are used once weeds have erupted from the ground and are actively growing.
