Why Gardeners Bury Rotten Logs Under Vegetables

After drought and wildfire in southwest Oregon, researchers found rotting logs about 25 times wetter than the soil around them. Gardeners turned that into hügelkultur, a mound bed built over buried logs that is often called centuries old and said to water itself for twenty years. In this video: what the forest really does with fallen wood, from Douglas-fir logs that kept getting wetter for their first 80 years on the ground to logs in the open that lost about half or more of their rain back to the air. Then the garden copy. The earliest known instructions come from a 1962 booklet by Herrman Andrä, who got the idea from a woodpile in his grandmother's garden, and his own mound lasted five to six years and came with watering instructions. We also look at Sepp Holzer, the Austrian farmer who developed the beds further. Then where the copy goes wrong, and how to build one that works: why rotten logs beat fresh ones, the nitrogen buried wood can lock up, settling and fruit trees, tall raised beds half filled with logs, wet ground versus sandy ground, which side of the mound dries out first, rodents, and a plain soil mound for when you have no logs. Old, nearly forgotten know-how, checked against the research. That is the whole channel.
