Lime Lawn: How to do it right

The Content Of The Article:

Many hobby gardeners lime their lawn every winter - supposedly to stem moss growth. However, this is a common misconception. The lawn moss is very tolerant to the location in terms of pH. It grows equally well on both acidic and slightly alkaline soils and the supply of lime can even promote growth.

First measure, then lime

Before limescale your lawn, you should therefore measure the pH of the soil, because only then you can supply the nutrient lime as needed. Corresponding, sufficiently accurate test sets are available in garden shops for little money. To get a reliable value, you should take some soil in several places in the lawn at a depth of about five to ten centimeters and mix the different samples well. Then pour the mixed sample with a little distilled water and measure the pH.

Densified soil acidifies quickly

Creeping acidification and other organic substances in the soil are not completely decomposed in the absence of oxygen, especially on moist and compacted soils. They begin to rot and thereby produce various organic acids that lower the pH in the soil. Since low pH levels limit the vitality of turf grasses, there are certain limits under which you should lime your lawn. On sandy soils, which have a low buffering capacity, the pH should not fall below 5.5, on loamy soil not lower than 6.5. For medium soil, the limit is 6.0.

Dosing lime correctly

The best way to lime your lawn is to use caustic lime - it is less aggressive than fire or slaked lime and is usually sold by gardeners under the name "garden lime". Meanwhile, there are also granular products that do not dust so much when spreading. The best time for application is autumn and early spring, once the snow cover has melted on the lawn.

Lime grass on sandy soil with about 150 to 200 grams of carbonated lime per square meter when the pH has dropped slightly below 5.5 (about to 5.2). For loamy soils with a pH of around 6.2, you need twice the amount, ie 300 to 400 grams per square meter.

Note that licking your lawn will not eliminate the cause of soil acidification. For this reason, you should also cover compacted soils each spring with a layer of coarse building sand about two to three centimeters thick. The sand is applied so high in the spring that the leaves of the grasses still look out about halfway. The back of a lawn rake makes it easy to level. The coarse grains of sand slowly sink into the ground, making it looser over time. It takes about three to four years to get an effect every year. The growth of moss then slowly returns and the grasses appear more vital and vigorous.
