Fighting moss in the lawn with lime - this is how it works

PH value test provides clarity about the lime requirement

Although moss is a pointer plant for acidic soil, you should use a straightforward do-it-yourself test to get final certainty. Liming only helps against moss when the pH value is actually too low for the noble lawn grass. Otherwise, buying sod lime is a waste of money. Test sets are available at every hardware store and garden center for around 5 euros. It is so easy to use:

  • Take soil samples from 10 places in the lawn from a depth of 8 to 10 cm
  • Mix these samples well in a container
  • Take 100 g of this and stir into 100 ml of distilled water

After 10 minutes, insert the test strip into the sample. With the help of a coloring reaction and the attached table, you can read off the pH value in the mossy lawn. If the result is well below 6.5, the moss is almost certainly due to a soil that is too acidic. Lawn grasses achieve their optimum at a pH value between 6.5 and 7.0.

Soil quality defines the correct dose

In order to rid the lawn of moss in the long term, it is important to use the right amount of lime. A pH value that is too low affects the growth of the grass, as does a too high, alkaline value. It is obvious that a light, sandy subsoil processes the lime much more effectively than a heavy clay soil. The following table gives tried and tested guide values:

How to properly lime your lawn

It is not enough to sprinkle lime on the moss-covered lawn. The material can hardly penetrate the dense felt to the roots. How to do it right:

  • Scarify the lawn lengthways and crossways in March / April
  • Sweep the combed out moss
  • Fill the lawn lime in a spreader and distribute it

Please pace the lawn with the lime spreader so that the strips do not overlap and there is an overdose. In the last step, you water the green area extensively.

Tips

If the noble grasses turn yellow in the mossy lawn at the same time, the problem is magnesium deficiency in addition to the low pH value. In this case, use dolomite lime. This is obtained from natural sedimentary rock and enriched with magnesium.
