When we bought our homestead, the only gardening area was at the bottom of a fairly steep hill. Though fine for growing a winter’s worth of potatoes and squash, it’s less convenient for greens, which we prefer to grow close to the house. Having read about a method called "lasagna gardening" (named for its layers; learn the basics here), we decided to try it. Egged on by its success, we extended the garden the following year only this time incorporating hugelkultur techniques. Here’s how we did it.
Hugelkultur is nothing more than making raised garden beds filled with rotten wood. This makes for raised garden beds loaded with organic material, nutrients, air pockets for the roots of what you plant, etc.
