Does Cutting New Grass Help It Grow | Results?

Does cutting new grass help it grow? Cutting fresh grass can benefit in its growth, but only if done properly and at the proper time. 

Before mowing your grass, wait for it to take root and only trim 1/3 of the leaf height. Then you’ll be helping with the thickening and healthiness of your new grass. To grow, grass requires photosynthesis, which is dependent on the leaf area catching the sunlight.

When you trim the grass, you lower the amount of leaf area available, thus the plant will try to compensate by producing as much volume as possible in the shortest amount of time.

As a result, the grass makes a determined attempt to produce runners and new growth.

This may not always imply an increase in height. If the grass is mowed on a regular basis, outward growth is more likely, resulting in a thicker lawn.

Stimulation of the Turf

When you mow the lawn, the grass responds by producing more growth to maximize photosynthetic processes due to the reduced surface area on its blades.

As a result, depending on the species, the grass focuses its energy on the blade and runner growth. Runners, for example, occupy the free soil area around the mother grass plant, allowing the lawn to benefit from increased photosynthesis.

Your grass develops into an interconnected layer with enough vitality to survive continuous mowing as well as other challenges such as heat and drought.

Excessive Mowing

Throughout the year, your lawn should not be mowed shorter than 2 inches.

Rather than sharing energy between the roots and the foliage, the grass focuses only on blade development. As a result, the roots become shallow and incapable of absorbing nutrients and moisture.

Even if the grass blade height recovers from the frequent mowing, it may have a brown, uneven appearance as a result of the inadequate root system’s inability to sustain development.

Lawn Mowing at its Best

A healthy technique for maintaining a vigorously growing lawn is to cut up to one-third of the grass length at a time. Sharpen your mower blades before cutting the grass; dull blades tear at the turf, leaving it vulnerable to disease and pests. 

Cut the grass in the morning or evening to avoid putting additional stress on the lawn during the hottest portion of the day. Vary your mowing direction over the turf as well to keep the blades erect and ready to cut properly.

The Advantages of Tall Grass

Allowing grass to grow slightly longer than 2 inches allows it to survive stressful situations such as protracted dry spells or heat waves. 

Apart from its ugly look, grass thatch thickens, obstructing water absorption into the soil.

Maintaining a regular mowing plan allows you to encourage healthy development and a vibrant soil environment.

When Should You Cut New Grass That Has Grown From Seed?

When a seedling starts to expand, it has not yet finished the development of its root system in the soil and lacks a robust leaf blade that can withstand lawnmower cutting and compaction.

As a result, after sowing your lawn, you should wait for it to grow for a while and gain vigor before mowing it.

Your lawnmower’s wheels and blades will lift your grass sprouts from the earth rather than cutting them if you cut the grass too short.

Furthermore, when a lawnmower runs on the ground surface, it compacts the soil, making it difficult for poor roots to spread underground.

If you’re installing plugs, sods, or sprigs in the spring, give them six to eight weeks before trimming them. Otherwise, merely tugging the grass’s corner edge will reveal whether it has begun to root securely.

In general, you should wait until the grass height reaches 3 to 4 inches and the ground is densely covered before pushing your lawnmower on your new turf.

It usually takes one to two months for your seeds to sprout in most circumstances. This time period is long enough for the turf to firmly attach to the soil and endure the impact of a trimmer.

Finally, before you mow your grass for the first time, lock your sprinkler system or hose reel to allow your lawn to dry out for two days. For reference, you can use the table below to determine the best time to mow your particular type of grass.

GETTING A THICKER LAWN IN FOUR STEPS | Does Cutting New Grass Help It Grow


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 will reveal whether your lawn requires lime or other soil additions to restore pH balance and nutrient availability, allowing grass to grow thick and lush again.


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.


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.
