The Snarky Gardener has several hugelkultur beds at Snarky Acres. Here’s his Mother Earth News article on them.
Hugelkultur beds are built using buried wood and other organic material. These ingredients break down over time, providing your plants with nutrients and moisture. Breaking down over the next 5 to 10 years, the wood will eventually transform into rich beautiful soil. I recently wrote about my hugelkultur beds at Snarky Acres for Mother Earth News, including what veggies I planted on them and how they are working out for me so far.
