Lime Soil - Strengthen your plants

The Content Of The Article:

Anyone who plants vegetables and herbs in the garden should lime the floor at least once a year. Lime ensures a fine crumbly and stable soil.

Lime the floor

The liming has another advantage: the plants are strengthened and thus do not break so quickly. The lime also makes them less susceptible to disease. 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 themselves is how much you should actually lime. Who thinks that the more, the better, is wrong. Because who limes too much can do exactly the opposite. Too much lime prevents so many nutrients from dissolving. However, with a simple soil test (for example, available here), you can quickly determine the correct amount of lime (instructions here). Depending on the soil, the pH should be at these values:

  • Loamy soils at a pH of 7
  • sandy loamy soils at a pH of 6.5
  • loamy sandy soils at a pH of 6
  • pure sandy soils at a pH of 5.5

If these pH limits are slightly undercut, it is sufficient if you sprinkle 150 grams of calcium carbonate per square meter every three years. So the pH of the soil remains stable. If the pH is a full pH below the limit, you must apply 250 grams of calcium carbonate per square meter to normalize the pH of the soil.

Pointer plants also provide hints on the lime content

If you take a closer look, you do not even have to do a soil test. There are also so-called pointer plants, which indicate a lack of calcium in the soil. These include e.g. Horsetail, farm mustard, pansy, rabbit clover, moss, dog chamomile and sorrel.

Nettle, deadnettle or shepherd's purse, however, indicate a high pH in the soil.

Which lime fertilizer is the right one?

Algae lime and carbonate lime are particularly suitable for humus rich soils. For heavy loam, on the other hand burnt lime is to be preferred. Garden lime, on the other hand, is best suited for light and medium soils. In general, however, it is sufficient if you deploy rock flour. It contains a lot of carbonate of lime, magnesium, potassium and various trace elements.

When is the right time for liming?

A good time to lime the soil is spring. However, you should only limescale your plants when they are dry or the soil is dry. You have to work the lime deep into the soil. If you did not manage to sink the soil in the spring, you can catch up on it in autumn.
