How to Level a Bumpy Lawn Like a Pro: 7 Simple Steps
Achieving a envy-worthy, golf course-like lawn involves leveling out those bumps. This 7-step guide covers the essentials, from understanding the causes of a bumpy lawn to choosing the right materials and tools.
We cover the importance of core aeration, applying biostimulants, and using fertilizer in the lawn leveling process. After reading this article, you will know precisely what you need to get a great result; just like a pro.
What Causes A Bumpy Lawn?
Understanding why bumpy lawns develop over time helps you identify the best strategies for treating the problem. Common culprits include poor sod installation and heavy traffic. Using the wrong mowing patterns or uneven watering can result in bumpy ground. Lawns can also develop undulations if they lack sufficient aeration. Compacted soil prevents root growth, making surfaces look like corrugated metal.
Animal activity can also play a role. Burrowing pests can lead to holes and raised areas, while pets can dig into the grass, removing material from some locations and depositing it in others.
Even the weather can cause disruption. Repeated freezing and thawing during winter can expand and contract the soil, leading to changes in its distribution throughout the season. Some areas may appear raised while others look lower down.
Droughts and excessive rain can have similar effects. Too much water can make soil clump to form bums when it dries, while too little leads to desiccation, cracking, and rutting.

How to Fix a Bumpy Lawn: Step-by-Step Guide
The following step-by-step guide shows you how to fix a bumpy lawn.
Step 1: Choose Your Leveling Material
You have several options for filling materials for a bumpy lawn, including topsoil, compost, or sand. You can also use a combination of these, depending on what you have to hand.
Combining sand and compost offers the best of both worlds. The compost boots the current soil’s organic material, while the sand adds structure. Topsoil is also an option and gives the grass a substrate it can use readily. An excellent compost choice is CarbonizPN.
CarbonizPN Soil Enhancer benefits all lawn types and can be mixed with sand to create a rich lawn leveling mix. It doesn't require immediate watering and can be used with granular fertilizer and other lawn care products.

Step 2: Acquire The Tools You Need
The next step is to gather the tools you need. For the best result, invest in a lawn leveling rake. This tool makes it more straightforward to smooth your leveling mix and achieve a flat surface.
You can use a standard rake and a shovel if you don’t have a leveling rake. However, it tends to be more work and the results aren’t as good as what a dedicated leveling rake will produce.

Step 3: Core Aerate Your Lawn
The next step is to assess your lawn’s situation and understand what might be causing the bumpiness. As discussed, it could be the weather, pets, pests, poor mowing techniques, and even poor drainage.
Core aeration is an important step in leveling a bumpy lawn by reducing compaction. The core aeration process removes small plugs from your lawn and relieves compaction by opening up the soil profile.
Before core aerating, ensure your grass is actively growing. Spring and fall are ideal times of year to core aerate. Ensure you water the lawn thoroughly a couple days before as this makes it easier to remove soil cores. You should also remove debris like heavy leaves and twigs from the lawn.
Step 4: Apply Essential-G Biostimulant
With the soil profile opened up from core aeration, now is the time to speed up recovery by adding biostimulants and fertilizer.
Essential-G™ is a versatile granular biostimulant designed to enhance your lawn's health through improved soil quality. One bag covers up to 4000 square feet, offering enhanced soil fertility and easy spreadability with a broadcast spreader. It contains compost, biochar, humate, reclaimed coffee grounds, and silicon, making it a comprehensive soil amendment.
Essential-G should be applied after core aeration to fast track nutrient uptake. The product is an eco-friendly choice for a responsible and sustainable lawn care program.
Step 5: Apply Fertilizer to Speed Recovery
Apply your chosen lawn fertilizer. If you’re unsure what the best lawn fertilizer for your lawn is, we recommend doing a soil test to see which nutrients are lacking in your soil.
One of the best top dressing fertilizers is Lebanon Turf’s Humic Max. It’s a high-performance fertilizer that will encourage a quick grass green-up and is excellent for all grass types.
Apply humic max at a rate of 3 lb per 1000 sq. ft. Alternatively, starter fertilizer can be used here too. When combined with Essential-G™ fertilizer will build up and enhance your soil quality.
Step 6: Fill The Low Spots With Leveling Mix
With the lawn biostimulants and fertilizer applied let’s move onto leveling your bumpy lawn. Fill low spots (holes or depressions in your lawn) with the sand, compost, or topsoil mixture. The goal is to make any low areas flush with the surrounding lawn. Your leveling rake will make quick work of this process.
Use your feet during leveling to compact the soil into the low spot. Then, add more leveling mix to top it up until it is level again with then surrounding turf. Keep repeating until you are happy with the results. Adopting this approach prevents you from having to re-apply more leveling mix later.
When leveling your bumpy areas, do your best to leave the grass tips exposed. This allows the grass to catch sunlight which promotes new growth and faster recovery.
If the bumpy area is large – perhaps due to the way the lawn was mown in the past – you can apply a similar process. Ensure the soil gets into all the depressions and low spots, evening them out. Use 1 cubic yard of leveling mix per 1000 square feet for good coverage.
Step 7: Water Lawn After Leveling
Once you’ve completed leveling the bumpy areas, water the lawn to help the material settle. You can use a watering can, garden hose, or automatic irrigation system.
You should notice the grass growing through the leveling mix in roughly one week. Done properly, your grass will regrow evenly, thick, and strong through the new, smooth surface.
Additional Tips For Leveling A Bumpy Lawn
Here are some more lawn leveling tips:
- Ensure you water your newly-leveled lawn regularly to improve grass recovery
- Choose the right time of year to level your lawn (which is late spring for most grasses but also the fall for cool-season species)
- The lawn leveling process is an ideal time to overseed cool season lawns
