Mowing the lawn – the 5 Best Tips and 5 Mistakes

The perfectly mown lawn ennobles every gardener. The velvet green carpet is of course not given to you as a gift. There are a few golden rules to follow when mowing the lawn. We have put together the 5 best tips and 5 mistakes for you.

Tip 1: Mow the lawn regularly

Periodic lawn mowing creates the basis for a dreamy, dense lawn. The more regularly you mow, the better the blades get used to the ideal cutting line. This results in a robust grain density with an advantageous effect on the photosynthetic capacity. Such a lawn easily copes with stressful situations of any kind. The ideal type of mowing is determined by the type of lawn, the seed mix and the location. The following information serves as a guideline:

  • Cut high-quality lawn every 7 days on average
  • Rapidly growing cheap mixes twice a week during the summer
  • Very slow growing shadow lawn every 10-12 days

Tip 2: Set the perfect cutting height

The issue of the optimal cutting height goes hand in hand with the question of ‘how often is mowing’. The ‘one-third rule’ has proven its worth as a reminder. Then a maximum of a third of the grass height should be mowed. The type of lawn and the prevailing weather dictate what height should be regarded as the ideal value. The following table serves as an orientation for the most common lawn types:

last cut in the year35-45 mm30-40 mm90 mm
absolute minimum height20-25 mm30-35 mm60-70 mm

If you mow the lawn according to the ‘one-third rule’, the mowing will be at an ideal height of 40 mm as soon as the stalks have reached 60 mm in growth.


You do not have to measure the individual blades of grass to determine the actual cutting height of your lawnmower. This is much easier: Simply place the mower on a flat surface and use a measuring tape or ruler to determine the distance between the knives and the ground.

Tip 3: Never cut in wet weather

When it rains, the lawnmower should remain in the tool shed. If a lawn is mowed when it is soaked, there will be no clean cut. In addition, the clippings clump and the lawnmower is overused. On top of that, the wheels of a heavy motor lawn mower sink into the wet ground and damage the grassroots.

Tip 4: Always mow with sharp knives and high speed

German hobby gardeners still prefer the motorized rotary mower for lawn mowing. So that the rotating knives conjure up a harmonious cut, they should be as sharp as possible. The cut surfaces present themselves frayed, the knives are in the workshop for regrinding. The winter break should also be used regularly to sharpen the cutting unit.

The speed of the lawnmower motor also has a decisive influence on the cutting pattern. If the cutter bar rotates at a speed of 3,000 revolutions per minute, you get a lawn as if it were peeled from the egg.

Tip 5: Do not leave clippings

If you do not use a grass catcher when mowing the lawn, the clippings are then spread over the entire area. While mulching is one of the fundamental maintenance tasks in the garden and ornamental garden, this fact has a counterproductive effect on the lawn. Fungus spores and other pathogens find ideal living conditions under the grass clippings to spread explosively from here.

It is therefore mandatory to sweep up and dispose of the leftovers with the rake after each cut. However, this premise does not apply if you cut the lawn with a mulching mower. This shreds the clippings into tiny pieces that act as a natural fertilizer.

Mistake 1: Cut lawn too early

When winter comes to an end, the lawn is reminiscent of a grown haircut. Understandably, ambitious hobby gardeners can’t wait to cut the lawn for the first time. If you start too early, you are doing a bad service for your green business card. You can recognize the ideal time for the first lawn cut of the season by these features:

  • The stalks have reached a height of 80 to 100 millimeters
  • Long periods of frost are no longer to be expected
  • The nightly temperatures no longer drop below 5 degrees

If you want to know exactly, from January all temperatures add up above 0 degrees Celsius. If the total is 180, the time is ripe for mowing the lawn and then scarifying.

Mistake 2: Mow the lawn too short

Every year during the holiday season, the image of the yellow discolored lawn is rampant in German hobby gardens. The cause is a cut that is too short after the return from vacation. If the lawn was allowed to grow unhindered for a few weeks, the vegetation point shifts upwards. If you mow to the minimum height in a single pass, the lawn falls into a state of shock. How to handle it correctly:

  • First cut the lawn at the highest cutting level of the mower
  • In a second stage, shorten the blades of grass according to the ‘one-third rule’
  • After a week, the cut is then cut to the ideal cutting height

Mistake 3: Mowing the lawn under the blazing sun

If warm summer temperatures and blazing sunlight come together, the time of day for mowing the lawn should be chosen carefully. If the lawn is cut at lunchtime, the stalks on the cuts will burn within minutes. The result is a brown-yellow lawn that is difficult to recover.

Ideally, cut the lawn in the cooler morning or evening hours. In order not to get into a clinch with the neighbors, the legally prescribed rest periods must be taken into account.

Mistake 4: Enter the uncut area

Actually, you had heeded all of the 5 best tips and still get an uneven cut after mowing the lawn? In this case, a widespread mistake has crept in that goes unnoticed in the zeal of lawn care. If the blades of grass are trodden down shortly before cutting, they will not straighten up in time. The lawnmower blades do not detect these points, which results in a wavy surface.

Mistake 5: Lawn mowing set before time

As the garden year approaches, one of the most common mistakes in lawn mowing comes to light. Aware that the lawn should go into the cold season long enough, mowing is stopped much too early. How to do it right:

  • As long as the weather permits, mowing takes place in the tried and tested cycle
  • The grass continues to grow until the first frost
  • After the first frost night, the lawnmower is used for the last time

Ideally, you have our small table on hand to read the optimal cutting height for the wintertime. Incidentally, there is no reason not to use the lawnmower to remove the remaining leaves later in the year. As long as the blades of grass are not mown again at the same time, use excellent work aid as a replacement for the leaf blower.

Tips & Tricks

Do you know the difference between a rotary mower and a cylinder mower? The rotary mower most commonly used in Germany cuts off the grass tips with rotating knives. The cylinder mower, on the other hand, gently cuts the stalks with a rotating cylinder, like with scissors. Incidentally, the cylinder mower is home to England, the motherland of the perfect lawn.
