Improve clay soil - with these 3 tips it works

Certainly, many plants like clay soils. But not all of them. So it's good to know how to improve clay soils.

Clay soils can densify In principle, everyone who has clay soil in their garden can count themselves lucky. Soil-rich soil is an effective nutrient and water storage that reduces your effort when watering and fertilizing. However, clay soils with a high proportion of clay can compact so strongly that ventilation is no longer possible. The lack of oxygen and high humidity often lead to root rot in the plants. In this case, you should improve the floor.

Last but not least, whether and how much you need to improve your clay soil also depends on the plants that are to grow in the garden. For example, most fruit trees thrive excellently in medium-weight clay and clay soils. Many other popular garden plants such as laurel, lilac, sparks and firethorn also feel at home in clay soil. With other ornamental plants such as rhododendrons, thorough soil improvement is essential for the good of the plants.

By the way:
You can recognize a heavily compacted clay soil by the fact that puddles stand up quickly even in light rain.

So you can loosen up loamy soil

Tip 1 - incorporate organic material into the soil:

Compacted clay soil can be optimized by mixing plenty of organic material into the top layer of the earth. Mature compost and shredded material are ideally suited for this. You can also work coarse sand into the clay soil. This creates cavities that improve water drainage.

Tip 2 - put drainage:

If the compaction of the clay soil is very deep, superficial improvements may not be sufficient. In this case, you can lay or have drainage laid. Suitable drainage pipes are available in garden shops and hardware stores. However, the effort for a large-scale drainage system is very high. You should only bother after consulting a specialist.

Tip 3 - vigorously dig up the clay soil in autumn:

Another way to improve your clay soil is by digging vigorously at the end of the growing season. Water can easily penetrate the excavated soil. As soon as it freezes in winter, the water molecules expand and separate coherent chunks of clay. In spring it is then advisable to fill up a layer of humus. On the one hand, this provides important nutrients and, thanks to the dark color, helps to conduct heat into the earth. Loam soil with a largely closed surface remains cold for a long time in spring and delays plant growth.
