Weed in the lawn is a thorn in the side of many amateur gardeners. If mushrooms then appear, attempts are made to master the situation with all possible means.Mushrooms in the lawn are often an eyesore
In the evening, examine the beautiful green lawn and then in the morning: the lawn is full of mushrooms. In itself, this is not a bad thing, but for many garden owners it is an unsightly condition if small mushrooms sprout everywhere in the lawn. Especially when the so-called hat mushrooms appear in a circle. One then speaks of a witch ring. Getting rid of it is not that difficult. You only have to consider a few important points.
Causes of fungi in the lawn
Fungi in the lawn occur when the soil is low in nutrients, the lawns are heavily matted or when the soil is too moist. In most cases, waterlogging has formed either due to the weather or excessive watering, which then provides ideal conditions for the fungi at warm temperatures. You can also get the problem with turf. This problem is mostly due to the high proportion of organic material in the turf substrate.
You should never do this against the mushrooms
A big mistake that many make is to leave the mushrooms on the lawn or mow them with a lawnmower. You should avoid this as far as possible because this will spread the spores over a large area and the fungi will only spread even more. You should therefore remove the fruiting bodies before mowing.
So you get rid of the mushrooms again
Aerate the lawn:
To prevent waterlogging on the lawn, it is advisable to aerate the lawn, i.e. aerate it. It is best to use a special aerating device. It is a device that has spikes on the underside and thus perforates the bottom. Alternatively, you can also use lawn-fan shoes that have soles with spikes. Then you just have to walk across the lawn. You can find out more about all aerating devices here. By the way, the best time for aerification is spring between March and May or autumn between September and October.
Scarify the lawn:
It also does no harm if you scarify the lawn once a year in spring (March to May) or in autumn (September to October). This works best with an electric scarifier, which you can borrow in any construction and garden center. This device has knives that penetrate the soil vertically when scarifying and loosen the soil. You can find out here how to proceed properly with scarifying.
Mushrooms in the lawn can also be a sign of a lack of nutrients. So there can be no harm in treating the lawn with a slow release fertilizer that is nitrogenous. We recommend e.g. Compo lawn fertilizer with long-term effect (e.g. available here). It is suitable for play, sports and decorative lawn areas and, with its long-term effect, ensures a dense, lush green lawn that defies moss and weeds.
Liming the lawn:
The mushrooms thrive particularly well on acidic soil. To prevent this, it is advisable to limescale the soil, because limescale raises the pH of the soil. How much you need to limescale is revealed by a so-called soil test (here is a guide). With light, sandy soils, you only need to limescale a little. With a light soil with a pH of less than 5.5, 150 grams per square meter are sufficient. For loamy soils, it should be 300 grams per square meter. If the soil has a pH above 6.9, you do not need to limescale.
