This principle also applies to the vegetable garden. Here too, the soil must always be provided with "fresh food" – and mulching is a sensible, sustainable measure in this context.

Mulching is a boon for any garden soil and an important cornerstone of organic gardening. For centuries, both vegetable and ornamental gardens have been covered with a protective layer, and for many good reasons.

• Mulching protects the soil from drying out due to sun and wind. The soil stays moist longer, saving water and reducing the workload in the vegetable garden.
• Mulching prevents erosion from wind and heavy rain showers; the rainwater is absorbed by the mulch layer and gradually released to the soil instead of washing away the valuable topsoil.
• Mulching suppresses weeds; less weeding is needed compared to without it.
• The mulch layer promotes a stable soil structure and healthy soil life. Many microorganisms find a habitat under the mulch.

• Large leaves from plants like comfrey or rhubarb are ideal for mulching. Lettuce or other vegetable leaves are also excellent choices.
• Nettle leaves are excellent mulching material because they decompose quickly and, with their high nitrogen content, serve as a good fertilizer.
• Straw is great for strawberries, berries, and tomatoes. It dries quickly and reduces the chances of fungal spores.
• Grass clippings can be used in principle, but only when dry. Wet grass clippings become matted, rot, or form an impenetrable layer.
• Bark mulch is not suitable for the vegetable garden because it contains tannins. It is recommended under trees, ornamental shrubs, and roses, as well as for walkways.
• Mulch compost (about 8 weeks old) from the compost heap is a valuable mulching material.
• Newspaper or cardboard can also be used to cover the soil. For an attractive appearance, add a layer of straw on top.
