You receive organic perennials in cardboard pots, made from unbleached, naturally degradable paper pulp. The pots can remain around the root ball and go into the ground.
You probably remember them, the 'Albert Heijn vegetable gardens'. The mini growing pots are made of the same biodegradable material as our pots and can even be placed in the organic waste bin - in small quantities. Because this is also a clean, natural product, made from wood fibers, water and natural additives.
Improve soil
Our organic plants can be planted in the ground, pot and all. Cardboard has been used by many vegetable gardeners for decades to clear soil. The soil is covered ( sheet mulching ) to keep out weeds, improve the soil structure and stimulate and nourish soil life. To speed up the process and improve the soil structure even more, compost, animal manure or other organic material is often placed on top of the 'sheets'. In agriculture and horticulture, (bio)plastic is mainly used to cover soil, but cardboard is also being used on an increasingly large scale.
From compost to humus
Cardboard can therefore become part of compost with this method. Organic material, such as leaves, prunings and other green waste, are transformed with the help of micro-organisms into a natural, dark brown to black, crumbly, nutrient-rich product. In nature, compost becomes humus, which releases nutrients to the soil - and the organisms living in it, including plants. The speed of the transformation process from compost to humus depends on factors such as humidity, heat and oxygen. Under optimal conditions, the paper pot will decompose in the soil within one to two weeks. Our pot can therefore contribute positively to soil life. An additional advantage is that we do not create any residual waste, which happens with plastic growing pots.
Industrial composting
Industrial composting, where bioplastics can also play a role, is done with large machines that speed up the composting process. Read about industrial composting here .
