The Snarky Gardener built raised beds using hugelkultur
Hugelkultur is the German term for garden beds made with buried wood. The wood breaks down over time, providing garden vegetables with nutrients and moisture (as in you don’t have to fertilize and water as much, if at all!). The wood does not have to be brand new as rotted wood is actually better is some ways.
This fall, I decided to utilize this technique to build four 8 foot long by 4 foot wide by 3 feet high raised beds. In general raised beds are beneficial as they warm up earlier in the spring, keep humans (but not my dog) from compacting soil, and allow plants better drainage. Usually raised beds are built with a frame around the soil, but my beds have no borders. After completing each bed, I planted cover crops (turnips, spinach and clover) to minimize winter soil exposure. My long term plan is to convert more of my garden into hugelkultur beds, but wanted to perform a trial first, as putting these beds in is labor intensive, with all the wood gathering, moving, and burying.
