There are many reasons why is my lawn lumpy, a bumpy yard that has to be repaired.
- Bumps occur in the spring as the frozen, compacted clay soil thaws unevenly. Like a bunched-up carpet, it heaves and buckles.
- Animals, both wild (such as voles) and domestic (such as cats) dig holes in lawns.
- Children digging holes while playing might cause your lawn to become bumpy.
- When people or animals walk on excessively soft lawns, depressions can form (like in the early spring or after long rains).
- When used incorrectly, several home gardening equipment can also leave holes.
Fixing a bumpy lawn can sometimes be as simple as filling in the disturbed soil and topping it over with excellent topsoil (hopefully weed-free). If the holes are small, the current grass will cover them. Larger areas should be planted or even sod-patched.
Why is my lawn lumpy?
The first step is to figure out why a section of your lawn has sunk and created a depression. It is critical to eliminate the source before fixing the consequence. If the depression is an inch or deeper, it should be repaired by removing the sod, fixing the cause of the sinking, and then backfilling with new soil, leaving enough space for settling.
If the removed sod is still in good condition, it can be reinstalled, or it can be replaced with new sod or seed. A tiny dip – less than an inch deep – in a lumpy bumpy grass can be progressively repaired by sprinkling top dressing over it.
This is where compost-based blends come in handy.
People frequently mistakenly believe a lawn is rough when it has nothing to do with soil! The soil, roots, thatch, and blades are only a few of the many layers that make up the grass. The patch immediately above the earth that protects the roots is known as thatch.
Bumps and rises must also be diagnosed before they may be corrected. If an object is to blame, it must be eliminated. If a hump is caused by burrowing creatures, the area must be smoothed before it may be smoothed. Stepping on minor bumps might be able to flatten them.
Matted decomposing grass clippings and typically withering old grass plants that fade away when new plants are created are usually approximately 1/4′′-1′′ in height.
When a thin grass or a disease or insect infestation weakens an area (think Chinch bugs), the blades die first, then the thatch decomposes quickly, leaving bare soil. Rainfall, wind, and human activities reduce this barren land even further.
When compared to the surrounding area of a healthy lawn, this results in depression. This is referred to as the “illusion of a bump.” Multiply that by multiple locations, and you’ve got yourself a winner! You have a lumpy lawn, don’t you?

How to Improve a Lumpy Lawn Quickly
The lumps, bumps, dips, and holes in your grass could be caused by a variety of factors. Every lawn will eventually require some leveling to eliminate anomalies.
Water can pool in depressions in the soil, causing drainage problems that can destroy lawn patches. Lawns that are extremely uneven, especially for youngsters, might be harmful.
Only when you’ve determined the source of the uneven terrain can you decide on the appropriate therapy for a long-term remedy. If you try to remedy the problem before figuring out what’s causing it, you can end up wasting your time when the bump or valley reappears.
Here are a few reasons why your grass might be uneven:
- Spring thawing is uneven, and heavy garden equipment is used.
- Mowing in the same pattern over and over
- Grubs and voles, for example, are pests.
- Natural settling affects children
Lawns naturally settle over time, and with new construction, the first few years will most likely be uneven. Topdressing can be used to repair shallow or tiny regions. If the grass has settled by an inch or more, the sod may need to be removed, back-filled, and then replaced.
Soil made of clay
During the spring thaw, if you have clay-heavy soil and live in a region where the soil freezes in the winter, you may notice new bumps and bulges in your grass. Heaving and buckling are caused by the clay soil, which occurs as a result of uneven thawing.
Aeration will help to break up the surface dirt, which will then be redistributed. It also makes it easier for water and oxygen to reach the roots. To level any residual low-lying areas, topdress with excellent topsoil or fine compost.
Gardening equipment can create ruts and holes. Ruts can form on your lawn if you mow it, in the same way, every time.
It’s the Best and Worst of Times in Spring
Spring brings the ideal weather for grass, with warm days and chilly nights, making it an ideal time to mend lumps and bumps. If the earth is wet, it can also be the worst moment. Walking on the lawn may be causing more harm than good. Wait till the earth has dried up before proceeding.
How to Make Your Lawn Level
For mild issues, topdressing with high-quality topsoil or compost may be the best option. Before topdressing, cut the lawn or affected area very shortly. It will be easy to see and level the area.
Apply no more than 12″ at a time, gently leveling it without covering the grass entirely. The grass will continue to grow after the topdressing has been applied. If a half-inch of soil isn’t enough, topdress the area for several months until it’s level.
If a deeper but small hole is surrounded by a healthy lawn, you may be able to fill it in by leveling the hole with soil and letting the grass fill in. Larger sections will require seeding or sod patching.
Are you thinking of using a roller to level your lawn? Here’s my recommendation: DON’T DO IT! It’s the worst thing you could possibly do. Although it appears reasonable, grass will not grow in the tightly compressed soil generated by leveling with a rake.
Keeping your lawn thick and healthy is the greatest method to avoid lumps and bumps. Aerate the soil on a regular basis to loosen it and allow more water and oxygen to reach the roots. Lawns can be thickened by overseeding. To maintain your lawn lush and green, use a nitrogen-rich fertilizer like Milorganite on a regular basis. Keep an eye on pest issues before they go out of hand.
Lumps and lumps are very normal. Determine the source of the problem before deciding on a long-term treatment rather than a band-aid.
What are lumpy lawns caused by?
Lumpy lawns are common in Colorado and are caused by earthworms and nightcrawlers. Earthworms in a lawn are a sign of healthy soil because they eat thatch, grass clippings, and other organic matter, recycle nutrients and aerate the soil.
This improves the health of the lawn. Since worms are good for a lawn, it is best to mow the lawn as high as the mower can be set and leave the worms alone.
