How To Fill Low Spots In Lawn?

How To Fill Low Spots In Lawn

In this short guide, I will explain how to fill low spots in lawn.

With time, areas of a lawn can become uneven. That could be due to many reasons, settling, drainage issues, and various natural and unnatural causes. If you face extreme cases, you can solve the problem by topdressing with a thin layer of levelling mix (soil, compost, and sand). That is a good solution for widespread unevenness and roughness that does not run too deep. More extensive variation in level may demand multiple applications of topdressing.

In more extreme cases, fill in deep depressions with soil and reseed over the filled areas. 

If unevenness appears near water pipes, including drainage issues, consult a professional. You might have a damaged pipe that’s causing the problems. One trick for levelling small depressions or holes covered with healthy grass is to cut out a patch of the turf. Add the soil mix underneath it.

Lay the patch back down. That is a handy technique for levelling localized depressions without having exposed soil’s unsightliness on the grass. Spring is the best time to level your lawn as the conditions are mild. It gives the lawn a chance to recuperate before summer’s heat arrives.

Topdressing includes spreading a levelling mix of topsoil, compost, and fine sand. The soil should not contain plant debris or dirt. It can smother the grass. Play sand is the best sand that can be used in this regard. You can buy that at any home centre. A typical mixture should be 40 per cent sand which provides good drainage, 40 per cent topsoil, and 20 per cent compost which adds nutrients to the soil to promote grass growth. 

  • Use a shovel to mix a batch of levelling mix in a wheelbarrow or tub. Mix in a way that the sand and compost are thoroughly blended with the soil.
  • On top of the low areas, apply up to 1/2 inch of levelling mix. Please do not add more than 1/2 inch because it can smother the grass. 
  • Rake the topdressing to spread it out evenly and nicely.
  • Make sure you brush the grass back and forth with a push broom. It will work the levelling mix down while lifting the grass blades. The grass cannot flourish if it’s covered with soil. 
  • Water the area lightly, only as much as needed. Prevent from over-watering, which can wash away the levelling mix.
  • Observe the progress in the area. Finally, you should see just grass and no dirt. That could only be possible if there were no bare spots before you began the process of topdressing. If the lawn is still uneven and rough, repeat the topdressing process. Apply no more than 1/2 inch at a time until it is level and even. 

Sweeping the dirt under the carpet

This procedure is so named because you are essentially picking up turf (the carpet) and, after that, putting dirt under it. It has one limitation, though. It is suitable only for small sunken areas that are covered with healthy and lush grass. 

Cut through the turf along with the corners of the sunken area. For this, you will have to use a flat spade or manual lawn edger. Make clean, vertical cuts and stripes. That will minimize root damage and form a neat patch of turf. 

Remove the turf patch carefully. Please do not damage the roots and set them aside. Don’t rush.

Spread a layer of debris-free topsoil. It should be enough to bring the turf patch level with the surrounding lawn. As you work, water the soil lightly and gently to remove air pockets. That helps to avoid future settling.

Replace the turf patch as nicely as you can. Press the grass back into place with the help of your hand or foot.

It’s time for you to water the grass.

Monitor the patch carefully, and water as needed, not much, not less. That will keep the grass healthy and lush. It requires extra care and gentleness to recover from the stress of being removed. 

Levelling Deeply Sunken Lawn Areas

Depressions, troughs, or holes that are deeper than 1 or 2 inches need to be filmed with good soil. Start over with new grass seed. Bringing up deeply sunken areas with topdressing takes too many applications. You’ll spend more time trying to keep the grass alive than you will be getting new grass to grow and flourish. You have to use a trick to make things work. The trick to fill deep holes is to compact the soil gently first. Please give it some water to settle it as you fill up the hole. If you pile on some loose dirt and plant your seed, the soil will settle evenly. 

You’ll get a sunken area covered with nice, new grass that you wanted. To compact the soil, you have to walk on it. Take care of one thing, though. You should not compact the top-most soil where you will sow the grass seed. You must prepare the soil and seed the area by following the seed product instructions and recommendations. 

As you know how to level a lawn, you do not need to go out and hire an expensive professional. With a bit of time and dedication, you can fill uneven lawn ruts and depressions in no time.

What kind of dirt fills low spots in the yard?

Make a top dressing mix. Remember it is to fill in the area beneath the grass in sunken areas of your lawn. It must be from two parts sand, two parts topsoil, and one part compost. The sand helps maintain a level yard because it doesn’t compact easily. On the other hand, the soil and compost contain nutrients that your grass needs to thrive and grow. 

Can you put soil over grass?

An effective form of repairing a lawn could be adding soil over your grass. It is possible to dump new soil over the top of what you have. Afterwards, prepare it for sod or seed. If you are not putting down a thick enough soil layer to kill everything underneath it, you may have to make some other plans.

Will a roller flatten my lawn?

Make sure you use your roller in moderation. However, if your soil does become compacted, you might be able to get it healthy like before and lose again by aerating it. The safe and adequate use of the roller is important. You can flatten your yard and make it easy to walk across.

When Should I aerate my lawn?

The appropriate time to aerate the lawn is very important. The best time for aeration is during the growing season. The growing season helps the grass heal and fill in any open areas after removing soil plugs.  Aerate the lawn with cool-season grass in the early spring or autumn. The ones with warm-season grass should be aerated in the late spring. 


You can easily make your lawn patching soil. For this, you will have to mix sand and dry topsoil in equal parts of half-and-half. After that, spread the levelling mix into low-lying areas of the lawn. Some people also make use of compost. The best thing about it is that it is excellent for enriching the soil.
