Hügelkultur (German, meaning “hill culture” or “mound culture”) is the garden concept of building raised beds over decaying wood piles. Decayed timbers become porous and retain moisture while releasing nutrients into the soil that, in turn, promote root growth in plant materials. (no link, image only)
Dig a hole in your garden area about the size and depth of a large coffee can (8 in. x 8 in. x 8 in.) and fill it with water. Time how long it takes for the water level to drop. If in one hour the water level has dropped by 1/2 in., you can figure the soil drains an inch in two hours. At this rate, the garden soil will handle 12 in. of water in a 24-hour period, making the ideal depth of this garden 12 in.
La butte sandwich a pour objectif de reconstituer un sol fertile (vivant) et adapté à une agriculture naturelle et durable. Elle présente l'avantage de fournir dès la première année et sans aucun intrant (seulement de l'eau) une production satisfaisante de légumes.
Keyhole garden. Designed for arid environments with poor soil, it's a raised bed system with a built in compost basket. Self fertilizing, and super efficient at holding in moisture. Can be built in a day. Uses 1 gallon of water a day.:
Hügelkultur Bed. Hügelkultur is a raised plant bed built over decaying wood and compostable materials. A fallen tree becomes a “nurse log”, decomposing, releasing nutrients, and nourishing new growth above for years, even decades. As the wood decays, it becomes more porous, storing water like a giant sponge, and releasing it slowly back into the bed’s soil. This means less plant watering; some gardeners report their beds thrived all season from rainfall alone.
