In this short guide, I will be answering to your question of how to flatten a lawn.
When we talk about mowing the lawn, there’s nothing more frustrating than trying to manoeuvre over lumps and bumps. A level and even lawn don’t just look nice. It is, therefore, easier maintenance, and it can have a few other advantages too. There could be many issues that a level lawn can remove. Levelling and grading the lawn can assist in encouraging water flow away from your property. It will allow more water to be absorbed into the soil, adding needed nutrients.
How to Flatten a Lawn
So if your lawn is looking uneven with a few too many dips, you have to follow this procedure. Before starting, the lawn will need to be checked thoroughly. Determine how much of your lawn requires levelling. Also, look for already occurring drainage problems. Drainage problems or even damaged water pipes can lead to uneven lawns.
Check for low spots and drainage issues
If there are low spots in locations around water pipes, seek professional advice before continuing further. If drainage issues are found, it is recommended to re-grade the lawn as well as levelling. It will create a surface that slopes away from the property to aid drainage. It will also avoid flooding.
Alternatively, an underground drainage system can be fitted. The instruments used could be either gravel or flexible drainpipes. Other reasons for bumps and hollows can be wear and tear, mole damage, drought or frost. There are two main methods for levelling a lawn. It depends on the extent of damage to the area. All low spots across the garden should be checked for depth. It will help decide which method will work best. Both ways will require the same mixture used when you are top dressing a lawn.
It will have a composition of two parts sand, two parts topsoil and one part compost. These combined will fill out the desired areas. That will improve drainage. The compost will allow for nutrient-rich soil to be formed.
Pre-water your lawn for levelling
A few days before you decide to level your lawn, you need to water it properly. That will ensure that the soil is not too hard, dry or powdery when making the adjustments. Be careful about not overwatering, as wet soil can be just as hard to work with as overly dry soil.
When to level your lawn
The best time to level your lawn is around spring. That will allow your grass seed time to grow in. Twill also provide sufficient moisture for the soil to settle inefficiently. There are two main methods for levelling. One is for low shallow spots, and one is for low areas deeper than 2-3cms.
Levelling low shallow spots on your lawn
A different method to level your lawn will be required for the areas that have sunk more than 2cm deep. You will need a squared-off shovel for this process. Use the shovel to slice into the centre and beyond the bump or hollow edges in a cross shape. It would be best if you tried to keep the cut as even as possible to make it easier to lift without getting it to break.
Cut to about 4-5cm deep. Then slide the shovel underneath. That is to cut each section of the cross horizontally. Also, keep the shovel as flat as possible for maintaining an even thickness of soil. That is where the soil mustn’t be too dry. It will crumble when moved if it is too dry. Gently peel back the edges of the turf. Keep peeling until you can lay them flat without breaking.
For levelling a bump in the lawn, dig out the excess soil. It will balance with the surrounding area. Tread down and fold the flaps of turf back over. Once you have completed all the areas required, check the grade and level of the lawn. That can be done by using a wooden 2×4 and a spirit level.
What causes a lawn to be uneven?
Several ways can cause your lawn to become bumpy or uneven. Here are some of the main reasons:
From your neighbourhood cats to pesky foxes, there are always some animals looking for food. Animals are one of the leading causes of uneven lawns. They will happily stray into your garden in the months where your lawn is at its most vulnerable. There are steps you can take to prevent them from ruining your lawn.
Kids usually play in the gardens. When the soil is soft, it can put a large amount of pressure on the lawn. That is bad for both the health of the grass and the surface will have to suffer long term issues.
When you are trying to perfect your lawns, more and more reasons to ruin them start appearing. The giant earthworms can be a real nuisance too. These little insects can shift between 20 and 25 tons of soil per acre to the surface every year. Keep the pH level of your soil low and prevent this problem from the beginning.
The weather can play a big part in causing lumps and bumps in your lawn, especially in the winter months. If surface water is allowed to stay on your lawn, it can cause long term damage. That is why getting your drainage right is so important.
Your lawn composition can be affected by things that occur beneath the soil, such as rocks, piping, and other debris. Excavate the affected areas to break up the rubble underneath. That could solve the issue.
Should I roll my bumpy lawn?
Rolling a bumpy lawn may smooth out a few animal tunnels, but it is only effective for the first 1-2 inches of soil. The actual purpose of rolling is to primarily get seeds or sod to settle them in your soil. If you have a hard bump in your lawn, rolling is not the right procedure to get rid of it.
Why is my lawn so bumpy?
Older, established lawns can become rough and uneven because the turfgrass compacts and thins over time. Freezing and thawing of the ground from season to season lift the soil. It also makes the surface bumpy. Animals digging through the lawn can also cause problems to the perfect even lawn.
Can you use sand to level a lawn?
Pure sand should never be used to level a lawn. Grass growing in the sand is also more liable to drought and cold injury. You should avoid putting sand on a lawn by itself. Instead, use a dry topsoil and sand mix for levelling uneven areas. Putting sand on a lawn without mixing is hazardous.
Topdressing with quality topsoil or compost could be your best solution for minor problems you face with the lawn. Before topdressing, you should cut the lawn or affected area very shortly. It’ll be easier to see the area. Next, level the topsoil. Apply no more than ½” at a time. Gently level it. Don’t completely cover the grass.
