Regular lawn mowing is the be-all and end-all of lawn care. This will ensure uniform green and at the same time prevent many lawn problems. With these tips, you’ll not only find the right mower, but also avoid the most common lawn mowing mistakes.
Lawns need to be cared for in spring and summer – preferably even weekly. Because only if it is properly worked, it looks really beautiful and remains weed-free. In addition to regular fertilizing of the plants, you ensure a dense, even green carpet with the right lawn cut. We give the best tips and explain what matters when it comes to lawn height.
How often should you mow the lawn?
As soon as soil temperatures rise above 7 to 8 degrees Celsius, the lawn begins to grow. Therefore, from April to October you should mow the lawn regularly – about once a week during the growing season is enough. This is because cutting not only makes the lawn walkable, but also ensures that the grasses grow nice and close together. For a beautifully dense lawn, it is better to mow off a small growth more frequently than to mow the lawn down less frequently but heavily. If you mow with mulch mowers, you don’t have to deal with grass cuttings, but you should do it once or twice a week, otherwise too many grass cuttings will fall onto the turf at once and become matted – the decomposing microorganisms literally choke on them.
When should you mow for the last time in autumn?
In the fall, growth subsides, so there is also less need to mow. The last cut in October or November depends mainly on the weather. Cut the stalks then to a length of about 3 to 5 centimeters.
When to mow for the first time in the spring?
Depending on the weather, do not mow before early or mid-April. In March, the soil is still too cold and the lawn grows reluctantly. If you scarify the lawn, you can mow it deep and fertilize it right away. Ten days later, the lawn is then strengthened and begins to grow properly. If the lawn has already grown by the time you scarify it, it is best to mow it deeply again. If you do not want to scarify, leave the grass blades a little longer when mowing for the first time in April so that the short-cut lawn does not catch weeds right away. In conjunction with dethatching, however, the lawn must be cut short.
The cutting height depends on the usage
The proper cutting height is 2 to 3 centimeters for pure show ornamental turf from appropriate seed mixes, and between 4 and 5 centimeters for utility turf. In dry conditions, the blades of grass should be left 1 to 2 centimeters longer; this also applies to shade lawns so that the blades catch the little light better. Tip: So do not shave the lawn down to the minimum before the vacation, but rather mow twice later.
Before the vacation, the lawn should not be cut particularly short. This increases the susceptibility to drought. If the lawn has grown particularly tall during the vacation period, bring it down to the usual cutting height in small stages.
The rule of thirds of lawn mowing
The rule of thirds states that you should only ever cut the lawn by one-third of the current lawn height.
Practical care tips for mowing the lawn
With some lawn mowers, the cutting height is not set in centimeters, but in several steps, from one to six, for example. Which level corresponds to how many centimeters can be found in the operating instructions. If in doubt, measure once.
If there is a lot of grass clippings, it is best to mix them with paper shreds or plant residues.
When mowing the lawn, do not step on uncut grass. This is because stalks that have been stepped on flat are very slow to straighten and will then not be cut at a uniform height.
After the vacation, mow in several stages to the original cutting height – also only one-third of the blade length at a time over several days. Then the vegetation points of the newly regrowing grasses will slowly shift back down.
Use the entire cutting width of the mower, this gives a uniform cutting pattern and is of course faster. The individual paths should always overlap by one wheel width.
Be careful when cutting lawn edges with a trimmed edge, the so-called English lawn edges. The lawn mower slides off easily and then literally scalps the turf.
In a sloping garden, mow across the slope. If you are always at the same height as the mower, it is safer and the cut will be more even.
Avoid these mistakes when mowing the lawn
1 mowing the lawn too rarely
If a lawn is cut infrequently, you can’t use it. But if it is cut too much, the grasses will not branch out either, the lawn will not be dense and will hardly be able to bear weight.
2 mowing too deep on a regular basis
Probably the most serious mistake. Letting the lawn grow high so that plenty of time can pass before the next mowing? Not a good idea. If you mow too deep, you cut off the regeneration point from which the blades sprout. This is about halfway up the blade. Grass that is cut too deep takes a long time to regenerate, and weeds shamelessly take advantage of this time and immediately spread. Short cut grasses react insulted especially in dry conditions, they become patchy and burnt brown by the sun. A very low set lawn mower can also directly damage the grasses.
A golf lawn with its extreme stubble is the result of many, many mowing steps. And this is really only possible with a reel mower. It would be fatal to mow a seldom mowed, long-grown lawn very deeply in one go. Once the grasses have been weakened by too deep a cut, mosses and weeds have an easy time of it and the lawn looks like a mossy patchwork after the season, or at the latest after the next winter. Even a shade lawn should not be cut too short. Leave it about an inch longer than lawns that grow in the sun. This is the only way the shade lawn can still make use of the low light.
3 lawn mower with blunt blade.
When mowing, always make sure the blades are sharp. Dull blades injure the grasses and make them susceptible to drought and disease. You can see the effect a few days later when the frayed tips of the blades dry up brown and the whole lawn is as if under a light brown haze.
4 mowing in wet conditions
Not only is this uncomfortable, but it also leaves a mark on the lawn. When the grass is wet, the mowers quickly get clogged in the discharge chute and the engine is put under a lot of stress. The clippings clump together, remain on the lawn or are not completely blown into the catcher bag. Gasoline lawn mowers can also sink into soggy ground or make deep tracks in the turf and soil with their rear-wheel drive, damaging grass roots.
5 mow immediately after fertilizing.
If you have a mower with a catcher bag, you should wait a few days after fertilizing the lawn to allow the granules to completely dissolve. Otherwise, you may end up removing some of the fertilizer with the grass clippings.
Where to put the grass clippings?
Mowing the lawn produces large amounts of clippings. Instead of simply disposing of it in the organic waste garbage can, you can recycle it as compost or mulch.
