Peat replacement is an important issue in climate protection. We explain which properties have made peat so successful in substrates and show good alternatives. If you are still wondering "What is peat“You can find out about this in our special article on the subject.

Why is peat in the garden soil?

Peat is a good base for garden potting soil. This is because it stores water well without the roots suffering from a lack of air and thus starting to rot. In addition, its pH value and nutrient content can be flexibly adjusted, depending on which plant is to be cultivated. Last but not least, it is nice and light when dry, so easy to transport.


Unfortunately, however, peat also has disadvantages: peat is a finite resource and its extraction and use emit CO2 free, which should actually be better stored in the ground. The further breakdown of peat prevents former bogs from being rewetted and prevents their work as a CO2-Memory can resume.
Because of its advantages and disadvantages, both professionals and hobby gardeners should rely on peat substitutes as much as possible.

Tip: You can also use our Plantura organic soil CO2 save. In our shop we offer peat-free and peat-reduced garden soils in organic quality, which protect the natural peat stocks.

Alternatives to peat

Environmental protection is important to every garden fanatic. But of course our green thumbs shouldn't have to suffer as a result. Alternatives to peat soils are mixtures of different materials that make gardening possible without peat. We would like to introduce you to common peat substitutes.

Wood fiber, wood chippings

Both are made from untreated wood scraps. They provide a loose, airy substrate, but hardly store any water. Wood fiber is not structurally stable. Chopped wood is coarser and therefore has hardly any water storage capacity, but has good drainage properties. Wood materials cannot store nutrients. With the exception of our Plantura organic turf soil, all Plantura organic soils contain wood fiber.

compost

Compost has the advantage that it has a high pH value and hardly sags. Compost can effectively store and release nutrients and water, which is why it is in all of ours Plantura organic soil is included. Quality assured substrate compost is free from plant pathogens and weeds.

sand

Sand can act as a source of iron in substrates, but otherwise hardly stores any nutrients. It is heavy, which is why mixtures with sand are particularly suitable for buckets that cannot be blown away so quickly. Mixed in in sufficient quantities, it ensures good water drainage and adequate root aeration, for example in our Plantura organic turf soil.

Bentonite

Bentonite is a natural clay mixture made from various clay minerals. These can swell when they absorb water. When used in substrates, they therefore increase water storage enormously. The clay minerals can absorb nutrients, store them and release them again when required. Because, together with compost, they greatly increase the fertility of the substrate, they are contained in our Plantura organic flowering plant soil and organic universal soil.

Expanded clay

Expanded clay is produced by the strong heating of clays. Compared to the starting material, expanded clay allows very little water and nutrient storage. When mixed in large enough quantities, expanded clay improves water permeability and thus root aeration, which benefits our Plantura organic flowering plant soil.

Coconut materials: coconut pulp, coconut fiber, coconut chips

Coconut pulp is the abrasion of coconut shells. Coconut fibers are completely loosened from the coconut and cut into small pieces. Coconut chips are the same fibers, but in a cube shape. All three are structurally stable and hardly store any nutrients. Coconut fibers and chips hold less water, but aerate the substrate well. Coconut pulp is in all of ours Plantura organic soil because it has properties similar to white peat.

Rice husks / rice husks

Rice husks are produced when rice is threshed. Rice husks are very light and provide a loose, air-permeable substrate. They cannot store large amounts of water or nutrients.

Perlite

Perlite is a volcanic glass that expands and becomes porous under great heat. It is pH neutral and does not hold any nutrients. It stores small amounts of water, but loosens substrates with sufficient admixture so that the roots are well ventilated. This is particularly important for young plants, which is why perlite is ours Plantura organic herb & seed compost loosen up.

Pine bark

Pine bark is obtained from the Mediterranean pine. It is structurally stable and ensures good ventilation in the substrate. It contains hardly any nutrients and can easily be adapted to the needs of each plant with fertilizers and lime. Our Plantura organic pine bark For example, it is natural and is produced sustainably from natural raw materials in the EU.

Xylitol

Xylitol is a preliminary stage of lignite, i.e. incomplete carbonized plant parts. It is a by-product of lignite mining. It is very structurally stable and provides an airy substrate with good water storage at the same time.

In addition to the alternatives mentioned, bark humus, broken bricks and vermiculite are also used in peat-free and peat-reduced potting soil. Are particularly popular Compost earth. Also the Plantura organic soil contain valuable compost. We explain how compost arises and how you Compost as a fertilizer can use. Or do you prefer to plant your plants directly in the ground? Then we'll show you how to make your Improve garden soil can.
