Ancient germanic planting technique: Hügelkultur and Hügelbedshttp://www.urbaniahoeve.nl/2012/06/hugelbedden-hugelkultur/?lang=enhttp://www.permaculture.co.uk/articles/many-benefits-hugelkulturHügelkultur is a composting process employing raised planting beds constructed on top of decaying wood debris and other compostable biomass plant materials. The process helps to improve soil fertility, water retention, and soil warming, thus benefiting plants grown on or near such mounds.[1][2]
Hügelkultur replicates the natural process of decomposition that occurs on forest floors. Trees that fall in a forest often become nurse logs[3] decaying and providing ecological facilitation to seedlings. As the wood decays, its porosity increases allowing it to store water "like a sponge". The water is slowly released back into the environment, benefiting nearby plants.[1]
Mounded hügelkultur beds are ideal for areas where the underlying soil is of poor quality or compacted. They tend to be easier to maintain due to their relative height above the ground.[3] The beds are usually about 3 feet (0.91 m) by 6 feet (1.8 m) in area and about 3 feet (0.91 m) high.[1]
