I have over-fertilized and "burnt" my lawn - what can I do?

If too much fertilizer has been applied to an area, e.g. because the bucket or bag has tipped over on the lawn, and you notice this in time, then you have a relatively good chance;

Here applies:Collect the fertilizer grains as best you can. You can use a broom or a rake for this, but you can also do it by hand, but please wear gloves. A vacuum cleaner should be used for the finer details. The area should then be sufficiently watered with approx. 15-20 l/m² of water. Repeat this process several times! This should prevent the lawn from drying out or "burning".

If the color of the lawn has already changed, there are usually two appearances:

1. It is yellowish, but there are still green stalks present
   When it first appears, the lawn should immediately be watered extensively with 15-20 l/m² of water and this process repeated several times so that the excess nutrients are flushed out. Do not fertilize again for the time being. After a few days, the lawn should have recovered and new blades of grass should form. If the affected area does not turn green despite repeated watering, then the lawn grasses are already too damaged. In this case, remove the brown grass, rake the soil a little and then topdress withLawn seedreseed. 
   

2. The lawn is completely brown.
   Extensive watering usually doesn't help with the second appearance, but you can do it anyway. Because then the soil in the affected area does not need to be replaced. For all those who want to have it green again quickly, we recommend digging out the brown spot to a depth of approx. 5-10 centimetres, filling the hole with turf soil and reseeding.

Why does the lawn turn brown ("burns") due to over-fertilization?
It is also popularly said that the lawn is burnt, but in reality it dries out. This is due to the high concentration of fertilizer salts in the soil, which damage the roots of the lawn.

Put simply, there are then more nutrients (minerals) in the soil than in the plant, which is not normal. This causes the water in the plant to return to the soil (exosmosis), causing the lawn to dry out.
