The pH in the soil is composed of the acid and base content and can vary extremely. The amount of this value depends on many factors and can also be actively changed by the gardener, if necessary. Naturally, plants are perfectly adapted to the pH levels of their original locations and need them in their new homes.
peatPeat is a traditional method that can lower the pH in the soil. This material has acidic properties and can be worked into the soil for a long time. However, peat is extracted from the bog, a very sensitive ecosystem that is gradually destroyed by mining. The extraction of this sediment negatively affects important habitats, and the flora and fauna there suffer extremely.
- Incorporate peat in the soil for several days to weeks
- However, removal of peatlands destroys the ecosystem Moor
- Better to resort to greener alternatives
Compost of oak leavesTo reduce the pH in the soil is also a compost of oak leaves well suited. This is easy to make, especially when an oak is in the home garden. In addition, oak trees grow in many parks and the German forests.
- Pure oak leaves have an extremely acidic pH
- When decomposing begins to release more acid gradually
- Even small amounts have a strong effect on the previous pH value
- Has no negative impact on the soil
- Pay attention to the purity of the compost, use only oak leaves
When spreading fertilizer and other products to lower the pH value, the soil should not be completely dug up. Mechanical and mechanical processing destroys soil structure and life in the soil. It can take weeks or even months to regain a healthy balance.
- Loosely loosen soil before applying
- Use a hoe, claw or rake to work only on the top soil layer
- Carefully insert the grave fork into the ground and move it back and forth
- Do not mess the earth layers too much
- Then gradually incorporate the product
indicator plantsAn important characteristic of a soil with too high a pH value are the pointer plants. Since most plants have adapted to specific values, these propagate naturally in an ideal location. Especially perennials then form large and healthy clumps without the gardener having to intervene to help. The alkaline soil is characterized mainly by a lot of lime, which does not tolerate all plant species equally well.
- Excessive growth of certain plants is indicative of alkaline pH soil values
- Basic soils are preferred by dandelion, field winch, cowbell, stinging nettle, field larkspur, poppy and coltsfoot
- Sage, chicory, dead nettle, calendula, cranesbill and liverwort feel well there
- Typical plants for calcareous soils are: spurge, toadflax, toadstool, goose thistle, honorary prize and sickle-carrot
- Chamomile is an indicator of neutral pH levels and soil compaction
- Pointer plants for acid soils are: sorrel, pansy, sorrel and horsetail
- Blueberries and holly trees thrive excellently in acid soil
- Bogbed plants such as rhododendrons, broom and lavender heath are dependent on low pH values
