Scarifying is the process of removing thatch from your lawn. Basically, thatch is that layer of dead, brown grass on top of your green, living turf. It’s caused by a buildup of organic material like leaves and stems. The problem with thatch is it can rob water and nutrients from your lawn, which causes discoloration or death in patches.
Every time you mow the lawn, it gets worse because you’re breaking up those layers even more. But what next after scarifying your lawn? This article will take you through all the necessary steps describing how to revive a lawn after scarifying while also explaining everything you need to know and do to get the best results.

How to Revive a Lawn after Scarifying
Once you scarify your lawn, the first step is to look back and check if you exposed any underlying problems. This means checking if you neglected any dead patches of turf, especially from damage caused by digging from pet areas or garden beds.
Also, check if there are signs of weed infestation, pests, or fungal diseases. This helps you with your future lawn care schedule by allowing you to engage a remedy quickly.
1. Raking and Removing Debris
Raking and removing debris is a necessary step to revive your lawn after scarifying. If the scarifying machine doesn’t have a collecting bag or box, you’ll first have to rake up the debris.
This involves large chunks of compacted soil, moss, dirt clods, and loose soil. The raking process also helps maintain a level surface.
2. Ensuring a Level Surface
After scarifying, you will notice that your lawn is no longer level. The cut grass on the surface will be at different heights, and you’ll see dips and peaks everywhere. It’s important to make sure the area is level.
This prevents tripping hazards, soil erosion from moisture or runoff, and uneven ground for your lawnmower to travel over. If grading the surface isn’t possible, you’ll have to use soil to level out the ground. This involves leveling out the hollow sections with topsoil
3. Soil Aeration
In the interest of growing a healthy lawn, there is another step you can take before replanting – soil aeration. Lawns need oxygen to grow and thrive. If the soil doesn’t have enough water or air, your lawn will dry out easily and die.
Soil aeration ensures that you have a healthy growing ground. It also helps with grass growth and fertilizer intake. You can use a lawn aerating machine or manually use a metal rake or garden fork.
4. Over Seeding to thicken the lawn
Scarifying your lawn is basically removing a significant portion of its turf, which causes thinning of the lawn. You must understand how to reseed a lawn after scarifying. Essentially, there is a need to replace the turf that you just removed. You can do this by either replanting or over seeding the lawn.
When overseeding, you must choose the right type of grass seed. For example, try to find a seed that is suitable for your local climate and weather conditions. However, make sure your seed is suited to the type of grass you already have.
5. Fertilizer Application
Fertilization is vital for any lawn, but it’s especially critical after scarifying when your grass is still in shock. The best fertilizer after scarifying will depend on the condition of your lawn, the climate and weather, and the type of grass you have.
For example, if your lawn is dry and stressed due to the winter months, a fertilizer with a high nitrogen content is recommended. If your lawn has a healthy green color, but poor root growth, a balanced fertilizer containing phosphate and potassium will work best. If you have warm-season grass, it’s best to wait until the end of spring to fertilize the lawn.
Overall the best fertilizer to use after scarifying should contain all three macronutrients: nitrogen, phosphate, and potassium. This ensures that your lawn gets the nutrients it needs to restore itself. You can apply buy a spreader or rent a fertilizer spreader from your local hardware store for this step.
6. Watering After Scarifying
Water keeps the soil loose and helps seeds germinate and grow. It also helps with the fertilizer intake of your grass plants. You can use a garden watering hose or sprinkler to water the area after scarifying.
It’s best to have a specific schedule to ensure that you water your lawn enough without overdoing it. For example, you can set up a sprinkler for one hour two times per day. This ensures that your grass gets plenty of water to restore itself, but not too much water that it drowns your plants.
How to Treat Lawn after Scarifying
Scarification is a great way to break up thatch in your lawn, making fertilizer intake, water absorption, and growth easier. However, the process of scarifying also thins the lawn, which is why you must take steps to ensure it grows back thicker and lusher than ever.
Treating your lawn the right way involves deep watering, seeding, applying fertilizer, and aerating the soil. Essentially, you must help your lawn restore itself through therapy.
Overall, this process will take some time to complete, especially since it’s best to do everything simultaneously. You can’t deep-water the lawn once without watering it again for a few weeks.
You need to constantly water your lawn while you’re aerating, seeding, and spreading fertilizer. You might need to do all of these things two or three times for a few months until you see results.
How do I Revive My Lawn after Scarifying? (FAQs)
Will grass grow back after scarifying?
Grass will grow back after scarifying as long as you regularly feed the soil with fertilizer and water. You must also aerate the lawn to ensure that oxygen, water, and nutrients reach the grassroots.
Note that it takes about four to six weeks for the new grass to grow back after scarifying. However, this will largely depend on your climate and weather conditions.
How many times should you scarify a year?
You should scarify your lawn once every year. The best time to scarify your lawn is in late spring or early autumn when the grass is not actively growing, and the topsoil is a little dry.
This makes it easier to break up and remove the thatch layer of your lawn without injuring the grass underneath.
How deep should I scarify my lawn?
You should scarify your lawn to a depth of about 3-20 mm. This is deep enough for removing thatch and aerating your soil, but not too deep where you damage or injure the grass underneath.
Remember, though, that scarifying deeper than 50 mm will leave your lawn vulnerable, especially if it’s still actively growing during this time.
Can you over scarify your lawn?
It is possible to over scarify your lawn and damage your grass plants. If you scarify too deeply or into the roots of your grass, then you might find that the grass will die and not grow back.
When scarifying for the first time, it’s best to do a small section at a time and see how far down you can go without damaging your lawn.
Understanding how to revive a lawn after scarifying is vital to restoring your grass to its lush green color. This involves leveling out the soil, aerating the space to allow water and oxygen to reach the roots, over-seeding or replanting if necessary, fertilization, and watering.
This steps are vital if you want to have a thriving lawn season after scarifying your grass.
