If you want to permanently own a healthy and dense carpet of lawn, you cannot avoid mowing the lawn regularly and properly. In a nutshell, we give you a few tips on how to mow your lawn correctly.

How often to mow the lawn?
The frequency of lawn mowing depends on the season. After all, weed is a plant like any other that changes its growth cycle with the seasons. In early summer the grass shoots up in a very short time, while growth slows down towards autumn and finally stops altogether in winter. Accordingly, the lawn should be mowed at least once a week during the strong growth phase from May to June. Depending on the growth, mowing twice may not hurt. In the hot summer months, mowing the lawn once a week or two is sufficient.
Frequent lawn mowing strengthens the grass plants. The lawn can then compact better and keep weeds in check.
The correct cutting height
The right height of cut depends on the type of lawn and whether it is in sun or shade. A usable lawn should have a cutting height of 3 to 5 cm. Decorative lawns, on the other hand, are usually kept at 2 to 4 cm. Cutting the lawn too low can damage the lawn. A very short lawn requires a lot of maintenance and needs regular watering. A lawn that is too short can be damaged by heat and suffer burns. On the other hand, if it is too high, there is a risk of moss formation. In addition, wild herbs then have the chance to spread.
Like other plants, lawns need sunlight to photosynthesize and grow. The lawn absorbs the sunlight through its leaves. Lawn that is in the shade should therefore be left at least 5 centimeters in order to be able to catch the necessary sunlight.
What to do with high grass?
Time has flown by again, it's mid-May, the lawn is in full splendor and hasn't it been mowed once? In this case, avoid radical solutions. Do not trim the lawn from 15 centimeters growth height to 2 centimeters ornamental lawn. The shock for the plants would actually be too great. If too much lawn is cut off at once, the grass plants will put all their energy into vertical growth. Few side shoots are formed, the lawn becomes less dense. Stick to the rule of thumb: Always shorten high lawns by a maximum of 1/3 and then bring the lawn to the desired height in a second or third pass, leaving the lawn a little break in between.
When to mow the lawn?
Lawns should not be mowed when wet. When the grass is dry, the cutting blades of the lawnmower can grip the blades of grass better and the plants suffer less damage. As for the time of year, the lawn should be mowed in the spring as soon as it begins to grow again. In autumn, the last mowing process should be carried out in November, so that the lawn is well prepared for the winter.
Lawn mowing times are regulated in Germany. Since 2008, the times have been readjusted and now follow an EU directive. The times for mowing the lawn are now regulated in the 32nd Federal Immission Control Ordinance and depend on the mower used. You are on the safe side if you mow your lawn between 9 a.m. and 1 p.m. and between 3 p.m. and 5 p.m.
For the exact times, it is best to inquire at your municipal office, as these can also vary locally.
Which lawn mower?
Which lawnmower is best for cutting grass? Whether you choose a roller mower, rotary mower or hover mower is of secondary importance. However, it is important that the knife blades are kept sharp (preferably sharpen once a year) so that the blades of grass are cut off accurately. This is how you get a beautiful lawn.
Why mow the lawn at all?
As a final point: does a lawn even have to be mowed? No. However, it then turns into a magnificent summer meadow within a very short time. This is beautiful to look at, but not suitable for lying down or playing. If your heart bleeds mowing the early summer flowers, you can consider leaving part of the lawn unmowed and letting nature play freely. This is certainly beneficial for the biodiversity in your garden.
