Liming the soil - Strengthen your plants


If you plant vegetables and herbs in the garden, you should limescale the soil at least once a year. Lime provides a fine, crumbly and stable soil.

You should limescale your floor at least once a year

Liming has another advantage: the plants are strengthened and do not break so quickly. The lime also makes them less susceptible to diseases. In addition, the lime regulates the acidity of the soil and promotes the spread of soil organisms that are important for the earth.

How much lime do you need?

The question that many hobby gardeners always ask is how much you should actually limescale. If you think that the more the better, you are wrong. Because if you limescale too much, you can do the opposite. Too much lime prevents some nutrients from dissolving. With a simple soil test (e.g. available here) you can quickly determine the correct amount of lime (instructions here). Depending on the soil, the pH should be at these values:

  • Loam soils at pH 7
  • sandy loam soils with a pH of 6.5
  • loamy sandy soils at pH 6
  • pure sandy soils with a pH of 5.5

If these pH limits are slightly fallen below, it is sufficient to sprinkle 150 grams of carbonated lime per square meter every three years. So the pH of the soil remains stable. If the pH is an entire pH level below the limit, you need to apply 250 grams of carbonated lime per square meter to normalize the pH of the soil again.

Pointer plants also provide information on the lime content

If you take a closer look, you don't have to do a soil test at all. There are also so-called pointer plants that indicate a lack of lime in the soil. These include e.g. Horsetail, mustard, pansy, hare clover, moss, dog chamomile and sorrel.

Nettle, dead nettle or shepherd's purse, on the other hand, indicate a high pH in the soil.

Which lime fertilizer is the right one?

Algae lime and carbonated lime are particularly suitable for humus-rich soils. On the other hand, quicklime is preferred for heavy clay soils. Garden lime, however, is best suited for light and medium soils. As a rule, however, it is already sufficient if you apply stone powder. It contains a lot of carbonated lime, magnesium, potassium and various trace elements.

When is the right time for liming?

A good time to limescale is spring. You should only limescale your plants if they or the soil are dry. You have to work the lime deep into the earth. If you have not been able to limescale the ground in spring, you can do it in autumn.
