There are no flat surfaces by nature, because irregularities are caused by vegetation and the burrowing activities of animals. Such structures are not desirable in the garden, so that a lawn straightening is necessary, especially on newly acquired plots of land.
Rolling after leveling is not advisable
fill in imperfections
With this method, you can even out irregularities without having to dig up the ground. The existing lawn is retained and can continue to develop. A disadvantage is that you have to repeat the measures until the lawn has reached a level.
How to proceed:
- Cut lawn in depressions as short as possible
- Fill in a layer of soil one to two centimeters thick
- spread some lawn fertilizer
- Press the soil gently with your foot
- Repeat the process when grass has grown through
Refrain from rolling the areas. The more compacted the substrate, the poorer the lawn will develop. By completely filling the holes in the lawn in one go, you reduce the amount of work. Enrich the soil mixture directly with lawn seeds, as the existing grass grows very slowly through the substrate in the case of deeper unevenness.
Break up or dig up the surface
A more radical measure is recommended for very deep and extensive differences in height. This is the case when the garden is characterized by molehills and sags through underground passages. Break up the lawn with a plow or loosen it with a shovel. The soil can then be spread evenly to create a flat surface.
flatten the plane
Stick wooden sticks into the ground at even intervals and stretch strings between the pillars. This construction serves as a rough guide to form a smooth surface. Then use a straightedge with a length of two to three meters and use it to pull off the substrate. A long spirit level offers an alternative.
So that the hard work is not ruined by the next rain, you need to compact the surface with a light roller. Too much soil compaction means that the grasses will not grow properly and unevenly later on.
tips
Some hand rollers can be filled with water, allowing you to apply moderate pressure to the ground.
