Lawn ventilation is an important step that contributes to the health of the lawn and lets the roots of the grasses breathe properly. Lawns thicken over time and need to be revitalized to eliminate potential waterlogging and root growth. Aerification not only depends on the right time, but also on the right equipment, tools and work steps.

Who does not know that "> Timing for the lawn ventilation

One of the most important points in the ventilation of the lawn is the right time. Since the lawn only needs to be ventilated twice a year, it is important to keep a close eye on the amount of time it takes for the lawn to be used effectively. The more accurately the time periods for ventilation are met, the faster the lawn can recover.

The best times are:

  • March or April after the first mowing
  • September or October

The reason for this is the previous months. Airing in the spring helps the soil and grass roots to recover from the cold, snow masses and moisture that has prevailed for several months. Especially after a long winter, the soil is highly compressed and should therefore not only be scarred in spring, but also ventilated. The aeration in the fall is also chosen as time, so that lawn and soil can prepare for the coming winter. Over the summer months, the following causes are often the reason for further consolidation:

  • Stress by children playing
  • Demand from pets, especially dogs
  • Meetings like a barbecue
  • Sports like football
  • Setting up various leisure activities, such as a pool
  • frequent sunbathing on small lawns

These are just some of the reasons why it is necessary in most cases to air the lawn again. This stimulates the supply of oxygen, the withdrawal of water and the formation of microorganisms, which ensures a better soil and turf quality before the winter months. Furthermore, the timing of the lawn ventilation on the weather. You should definitely choose a day within the time frame mentioned above, which will not be adversely affected by the following weather conditions:

  • long dry periods
  • frost

Frost and dry, hard soils will not only make work harder, but may also affect the roots of the grasses. For this reason, you should choose a day when there is no risk of frost, it is not too dry and the sun does not seem too strong. Cloudy days are the ideal time for airing in autumn. If your lawn is exposed to heavy use, it may be that the soil has already compacted after just two months. In this case, you will need to aerate more than twice a year to maintain the health of the lawn.

Tip: you can determine the right time even more precisely by using a penetrometer, as this measuring device penetrates the earth up to one meter and measures the compaction. If there is no compaction, you do not need to perform the lawn aeration, which saves you a lot of work and time.

Devices and tools

To make the lawn aeration as efficiently as possible, you need the right tool or tool, depending on whether you are working by machine or by hand. When selecting the device, you must be careful not to accidentally select a scarifier. Although this also helps with lawn care, but it does not penetrate as deep into the earth layers as the lawn fan. For the lawn ventilation in the spring you also need a scarifier, but this does not work for the deeper soil layers. The following aerators and tools can be found:

1. Motorized Aerators: An aerator that operates either electrically from a power outlet or from fossil fuels such as gasoline are devices that deeply perforate the lawn. The device is only guided by you, while the motor drives the spikes or fan claws that are responsible for the perforation. The choice of thorns depends on the soil conditions. Motorized aerators make it easier to ventilate larger lawns, but have long been prohibitive for individuals, which has changed. Acquisition cost for aerators:

  • Models for the hobby garden: 50 - 200 euros, depending on the manufacturer and performance
  • Models for the professional sector or lawns over 500 m²: from 1, 000 to well over 4, 000 euros

As you can see, the expensive devices are not worthwhile. Einhell has proven to be effective in the field of mechanically operated lawn fans. But you do not have to buy a device yourself, especially if you rarely aerate. Maybe even once a year is enough for you. In this case, you should consider borrowing the device. The price for a day is between 60 to 120 euros, whereby the models offered are mostly high-quality aerators, which are similar in effectiveness to professional equipment.

2. Aerifying fork: the corrugator fork is the manual version of the aerator and can be used just as well. These are ideal for your own garden with a small area, as they require sufficient time and physical strength despite their specialization in lawn ventilation. They are equipped either with a handle that resembles a shovel or a frame that allows easy guidance for two hands.

The operation as follows:

  • are provided with hollow spoons
  • these are driven into the earth
  • Erdwülste be recovered by the Spoons and collected in the collection container
  • the holes are evenly distributed
  • depending on the model, different spoons can be used

The cost of a corrugated fork are usually much cheaper and are in the range of 20 to 100 euros, the more expensive variants are usually more robust. When choosing make sure that there are at least 2 spoons on the fork. Here, however, the more, the better!

3. Grave fork: the classic. The digger fork is the original tool for airing, but is physically exhausting and time consuming. In addition, it is inaccurate as the above-mentioned devices, since no earth is removed, but only holes are created, which brings the air to the roots. Nevertheless, a grave fork can offer effective, especially for small lawns. The costs amount to 10 to 40 euros .

A conventional pitchfork does it even with smaller lawns.

4. Lawn-fan shoes: This footwear is provided with five to ten centimeters long bottom nails, which are driven by the running motion into the ground. This tool is recommended only for physically fit people, as this work can be sweaty, especially on large or heavily compacted lawns. The cost of the purchase amounts to about 20 euros per pair.


Now it's time to prepare. This will prepare the lawn for the lawn aeration and ensure a smooth flow. The preparation in detail:

  • If the lawn has mossed over the spring, you first have to scarify it
  • if it does not require scarification, mow the lawn back to three to four centimeters
  • After scarifying or mowing, you must moisten the lawn slightly
  • However, this must not be under water
  • then select the appropriate spoons or thorns
  • These depend on the soil condition

If you are using a machine-operated aerator, you must be aware of the legal rest periods, as the device is quite noisy. Above all, on Sundays you should refrain from using the device so as not to disturb your neighbors. Hearing protection is recommended on some models.

Air Lawn: Instructions

After you have prepared your lawn for lawn aeration, you can start with it. You do not need any other utensils or materials except your implement. Proceed as follows:

1. Connect your aerator or pick up your aerator or digger fork.

2. Start airing by positioning the unit at a lawn edge. They should not start from the middle of the lawn, which would only make the process more difficult.

3. Now start the machine and guide it at a steady speed along the edge to the end of your lawn. Repeat this in the other direction, but place the device at a distance of 15 to 20 cm to the previous lane. Make sure that too fast a speed does not loosen the ground well enough, while if the speed is too slow the perforation will be too strong.

4. Continue until the entire lawn is perforated. Depending on whether you have a container for the earth sausage on your device, you should be careful not to step on it during the work. There should be approximately 200 holes per square meter to provide ideal conditions for the lawn.

5. Finally, dispose of the remaining soil on the compost.

6. If you sand the lawn with fine quartz sand (grain 0 - 2 mm) after airing, you will effectively improve the soil quality. You can also distribute a topdressing that provides a true nutrient boost.
