The short answer is yes, according to lawn care experts. Leaving grass clippings on the lawn can actually be healthy for the grass, as it helps build a strong and nutrient-rich soil. This practice is known as “grasscycling,” and it has become increasingly popular in recent years.
Yes, leaving grass clippings on your yard after mowing can be beneficial. They act as a natural fertilizer, providing nutrients back to the soil. The clippings break down quickly and release nitrogen, which helps promote healthy growth of your grass.
While grass clippings themselves won't sprout new grass, they can play a significant role in supporting new grass growth and even contribute to natural reseeding under certain conditions.
Yes, using grass clippings as mulch can help with bare spots in your lawn. Grass clippings provide a layer of organic material that helps retain soil moisture, suppress weeds, and improve soil structure. However, it's important to apply a thin layer of grass clippings to avoid smothering the existing grass.
Benefits of Not Collecting Clippings
Clippings return nutrients to the soil as they decompose. Clippings do not cause thatch. The belief that grass clippings cause thatch has been ruled out by recent research, which finds that thatch is composed mainly of grass roots.
As a general rule, grass clippings of an inch or less in length can be left on your lawn where they will filter down to the soil surface and decompose quickly. Remove longer clippings because they can shade or smother grass beneath causing lawn damage. Don't throw out bagged grass clippings as yard waste.
Mowing actually helps make your grass grow thicker because the tip of each blade contains hormones that suppress horizontal growth. When you cut the lawn, you remove these tips allowing the grass to spread and grow thicker near the roots.

Definitely yes! Hand-sowing is the simplest method if you only need to cover a few spots. Take a handful of seeds and spread them over the dead patch, or better yet, involve your kids and introduce them to some basic gardening chores.
It can but it's not in a rush, especially if your spots resulted from dog urine or lawn disease or even an accident with the mower. Weeds, though, will jump in at a frustratingly fast speed. So what's best for you to do is follow some important steps for filling in those bare spots on your own.
Lawn clippings do not significantly contribute to thatch development. Grass clippings may need to be bagged or raked and removed when mowing extremely tall grass. You may also want to bag the grass clippings and use them as a mulch in vegetable and flower gardens.
The theory that cutting short lengthens the time between cuts also doesn't hold up. Grass grows faster after it's been cut short as it tries to rebuild itself to its genetic norm. A good in-season height for most turfgrasses is 2½ to 3 inches — typically the highest setting on mowers.
During the spring and early summer months, grass grows much quicker than in the later summer months. It might be best to bag your clippings in the spring and early summer when your lawn isn't as pressed for moisture. During the summer months when the grass is growing slower, bagging might not be as necessary.
Generally, the depth of grass roots mirrors the height of the grass. Thus, when grass isn't as healthy (for example, in periods of drought), it is better to let grass grow taller and, in doing so, to strengthen the root systems.
If the grass comes out easily with no resistance, it is dead. Dead grass isn't coming back, so you'll need to take steps to regrow your lawn. You can replace the grass by seeding or sodding — or installing a new type of landscaping material such as mulch, rocks or groundcover.
When you cut the grass during the spring and summer, leave the clippings on the lawn. As they decompose, they release up to 30 per cent of the lawn's required nutrients.
Desirable turf grasses prefer moist soils to a certain depth, with a dry surface and leaf area. This provides them with the moisture needed for growth and an ability to withstand drought should it occur. It also keeps mold and fungus from developing on the succulent leaf blades where food is being made.
Leaving Clippings on the Lawn (Grasscycling)
There are many benefits of 'grasscycling' including natural fertilization, decomposing grass releases nutrients like nitrogen and potassium back into the soil, acting as a natural fertilizer for your lawn.
Very Small Patchy Areas: For tiny bare spots (think a few inches in diameter), throwing a small amount of seed and keeping the area moist might suffice. However, even in these cases, lightly raking the soil to create some seed-to-soil contact can significantly improve results.
Overwatering may cause grass to grow at an unusually fast rate. You might also notice a boost in your grass's growth right after it's been fertilized.
Overseeding can help you get back to the thick, lush, green lawn you're looking to achieve. By spreading grass seed over your existing lawn, you can thicken up the thin areas and get your lawn looking terrific again. (This is different from reseeding, which is when you start over and plant a completely new lawn.)
Clippings from weeds that have gone to seed may contain viable seeds that can germinate and proliferate, leading to an increase in weed population over time. By bagging clippings and disposing of them properly, homeowners can mitigate the risk of weed propagation and maintain a weed-free lawn.
Mow Properly
Using best practices for mowing helps your grass grow thick and stay that way.
Although grass needs energy from the sun to grow, it does not stop growing at night. It uses the energy it gathered from the sun during the day to make sugars, and actually grows most just before dawn. This is the secret about grass that only Master Gardeners know.
